If you’ve noticed rough patches, age spots, or precancerous lesions on your skin from years of sun exposure, you’re not alone. Millions of Americans develop sun-damaged skin each year, and many are turning to photodynamic therapy (PDT) as an effective, minimally invasive solution.

Unlike surgery or aggressive laser treatments, PDT uses a photosensitizing medication combined with light activation to target and destroy damaged skin cells while leaving healthy tissue untouched. It’s FDA-approved, recommended by dermatologists nationwide, and offers excellent cosmetic outcomes with minimal downtime.

At Campbell Dermatology, we’ve helped countless patients restore their skin health and prevent serious skin conditions using advanced PDT technology. Whether you’re dealing with actinic keratosis, extensive sun damage, or stubborn acne, this guide will help you understand how PDT works and whether it’s the right treatment for you.

What Is Photodynamic Therapy?

Definition

Photodynamic therapy (PDT) is a non-surgical, in-office procedure that uses a combination of light-sensitive medication and specific wavelengths of light to destroy precancerous and cancerous skin cells. The treatment is minimally invasive, requires no anesthesia, and can address multiple skin lesions in a single session.

The FDA approved PDT for actinic keratosis treatment in 1999, and it has since become one of the most effective tools in dermatology for treating sun-damaged skin and certain precancerous conditions.

How PDT Works

The PDT process involves five key steps:

  1. Photosensitizing Medication A light-sensitive compound—typically aminolevulinic acid (ALA), marketed as Levulan Kerastick or Ameluz—is applied topically to the affected skin area. This medication is preferentially absorbed by abnormal cells, including actinic keratoses, precancerous lesions, and certain acne-causing bacteria.
  2. Incubation Period After application, the medication sits on your skin for 14–45 minutes (depending on the specific formulation). During this time, ALA is converted into protoporphyrin IX, a fluorescent compound that accumulates in the targeted cells.
  3. Light Activation Your dermatologist then uses a specialized light source—typically blue light (415 nm wavelength) or red light (630 nm wavelength)—to activate the photosensitizer. The light energy causes a photochemical reaction that generates reactive oxygen species (ROS).
  4. Destruction of Abnormal Cells These reactive oxygen molecules destroy the targeted abnormal skin cells through a process called apoptosis (programmed cell death) and vascular damage. The treatment selectively eliminates damaged cells while preserving healthy tissue.
  5. Healing Response Your body’s natural healing response removes the destroyed cells over the following days and weeks, revealing clearer, healthier-looking skin.

Why Healthy Skin Is Protected

One of PDT’s greatest advantages is its selective targeting. Because ALA is preferentially absorbed by abnormal and precancerous cells—and not by healthy skin—the surrounding normal tissue remains virtually unaffected. This is why PDT can treat multiple lesions in one area without damaging healthy skin or causing significant scarring.

Conditions Treated with Photodynamic Therapy

PDT is FDA-approved and clinically proven to treat a wide range of skin conditions:

Actinic Keratosis (Primary Use)

Actinic keratosis (AK) is the most common precancerous skin condition in the United States. These rough, scaly patches develop from chronic sun exposure and can progress to squamous cell carcinoma if left untreated.

PDT is considered the gold standard for treating multiple actinic keratoses across a large treatment area (often called “field therapy”). A single PDT session can treat dozens of lesions simultaneously, reducing recurrence rates significantly compared to topical creams or cryotherapy used on individual lesions.

Sun-Damaged Skin

Years of UV exposure can leave your skin with:

  • Irregular pigmentation
  • Rough texture
  • Fine lines and wrinkles
  • Broken capillaries
  • Overall loss of elasticity

PDT doesn’t just treat precancerous lesions—it also improves overall skin quality and appearance. Many patients report smoother, more even-toned skin weeks after treatment.

Acne

PDT can be highly effective for moderate to severe acne treatment, especially when topical treatments or antibiotics have failed. The blue light used during PDT kills Cutibacterium acnes (formerly Propionibacterium acnes), the bacteria responsible for acne formation. Additionally, PDT can reduce sebaceous gland activity, decreasing oil production and future breakouts.

Rosacea

This chronic facial flushing and redness condition can be difficult to treat. PDT reduces the inflammation and blood vessel dilation associated with rosacea, providing significant symptom improvement in many patients.

Sebaceous Hyperplasia

These benign growths of oil glands become increasingly common with age. PDT effectively reduces or eliminates these lesions with minimal scarring.

Superficial Skin Cancers (Selected Cases)

In carefully selected cases, PDT can treat early-stage basal cell carcinoma and other superficial skin cancers. Your dermatologist will determine if PDT is appropriate for your specific situation.

Other Dermatologic Uses

PDT has been investigated for treating conditions including warts, lichen planus, certain fungal infections, and other inflammatory skin disorders.

Benefits of Photodynamic Therapy

Why Patients Choose PDT

Minimally Invasive No surgery, no scalpels, no stitches. PDT is performed entirely in-office with no downtime for most patients.

Little to No Scarring Because PDT destroys cells below the skin’s surface without creating an open wound, scarring is extremely rare—especially compared to surgical excision or aggressive laser treatments.

Excellent Cosmetic Outcomes Unlike cryotherapy (which can leave white spots) or topical treatments (which often take weeks to work), PDT produces natural-looking results with improved skin texture and tone.

Treats Multiple Lesions at Once A single PDT session can treat dozens or even hundreds of actinic keratoses across a large area—something that would require many individual cryotherapy treatments or weeks of topical cream application.

Targets Damaged Cells Only The selective absorption of ALA by abnormal cells means healthy tissue is protected, reducing the risk of adverse effects.

Lower Recurrence Rates PDT has lower recurrence rates than topical treatments like 5-fluorouracil (5-FU) or imiquimod, especially when performed as field therapy.

Quick Office Procedure A typical PDT session lasts 30–45 minutes from preparation to completion. You can return to your normal activities immediately (with sun protection).

Improves Overall Skin Texture Beyond treating precancerous lesions, PDT promotes collagen remodeling and can improve fine lines, roughness, and skin tone.

Who Is a Good Candidate?

Ideal Candidates for PDT

You may be an excellent candidate for PDT if you have:

  • Multiple actinic keratoses across a large area
  • Extensive sun damage and want comprehensive treatment
  • Fair skin with a history of chronic UV exposure
  • Precancerous lesions that keep recurring
  • Moderate to severe acne unresponsive to other treatments
  • Concern about scarring (prefer non-surgical options)
  • Time constraints (want results faster than topical treatments offer)
  • Cosmetic goals beyond just treating precancerous lesions

During a consultation at Campbell Dermatology, our board-certified dermatologists will evaluate your skin condition, discuss your goals, and determine if PDT is right for you. We can also perform a comprehensive skin cancer screening during your visit.

Who Should Avoid PDT?

Certain patients should not undergo photodynamic therapy:

Pregnancy PDT has not been studied extensively in pregnant women. We recommend delaying treatment until after pregnancy and breastfeeding.

Photosensitivity Disorders Patients with conditions like porphyria cutanea tarda or xeroderma pigmentosum should not undergo PDT.

Certain Medications Some medications increase photosensitivity, including:

  • Tetracyclines (doxycycline, minocycline)
  • NSAIDs (ibuprofen, naproxen)
  • Diuretics
  • Sulfonamides
  • Antimalarials (hydroxychloroquine)

If you take these medications, discuss with your dermatologist—you may need to adjust your regimen or timing.

Active Skin Infections Treatment should be postponed if you have active herpes simplex, bacterial infections, or other skin infections in the treatment area.

Allergy to Aminolevulinic Acid (ALA) Though rare, some patients are allergic to the photosensitizing medication. A patch test can help identify this before treatment.

How the PDT Procedure Works

Step 1 – Skin Preparation

Your dermatologist begins by gently cleansing the treatment area to remove any oils, debris, or makeup. Some providers may perform light microdermabrasion or use a gentle scrub to enhance ALA penetration.

The skin is then dried completely, as moisture can interfere with medication absorption.

Step 2 – Applying the Photosensitizer

Your dermatologist applies the photosensitizing medication evenly across the treatment area. The two most common options are:

Levulan Kerastick (ALA) A topical liquid applied with a roller or brush applicator. Effective and reliable, with a well-established safety profile. Requires 14–15 minutes of incubation.

Ameluz (MAL – Methyl Aminolevulinate) An alternative photosensitizer that’s sometimes preferred because it penetrates skin differently, making it particularly useful for thicker or difficult-to-treat lesions. Typically requires 30–45 minutes of incubation.

Your dermatologist will choose the most appropriate option based on your specific condition and skin type.

Step 3 – Incubation Period

After application, the medication sits on your skin for 14–45 minutes while it’s absorbed and converted into the active form (protoporphyrin IX). You’ll relax in our treatment room during this time.

Some patients experience mild tingling or itching during incubation—this is normal and typically very mild.

Step 4 – Light Activation

Once incubation is complete, your dermatologist uses a specialized light source to activate the photosensitizer:

Blue Light (415 nm)

  • More superficial penetration
  • Ideal for actinic keratosis, acne, and other superficial lesions
  • Shorter wavelength
  • Slightly higher pain during treatment

Red Light (630 nm)

  • Deeper penetration into the dermis
  • Better for larger, deeper lesions
  • Longer wavelength
  • May be combined with blue light for comprehensive treatment

Daylight PDT In appropriate settings (clear weather, sufficient ambient light), daylight can be used as the light source. This significantly reduces pain during treatment and is increasingly popular in Europe. At Campbell Dermatology, we can discuss whether daylight PDT is suitable for your situation.

The light is applied for 15–20 minutes, depending on the specific protocol and device used.

Step 5 – Post-Treatment Care

After light activation, your dermatologist applies:

  • Sunscreen (SPF 30 or higher)
  • Soothing moisturizer
  • Optional anti-inflammatory cream if significant redness is present

You receive detailed post-treatment instructions to maximize results and minimize side effects.

What to Expect During Treatment

During the Procedure

Pain Level PDT is generally well-tolerated, though not entirely pain-free. Most patients describe a warming or stinging sensation during light activation, similar to a sunburn developing in real-time.

  • With blue light, discomfort is typically moderate and increases slightly toward the end of treatment.
  • With red light, discomfort is generally milder.
  • With daylight PDT, discomfort is minimal to absent.

Burning Sensation You may feel a prickling or burning sensation during light exposure. This is completely normal and indicates that the treatment is working. We can adjust the light intensity or take brief breaks if needed.

Treatment Duration The entire appointment—from preparation through post-treatment care—typically takes 45–60 minutes.

What You’ll See Immediately after treatment, the area will be red and slightly swollen, similar to a mild sunburn. Some providers apply ice or cooling devices to reduce discomfort.

Recovery After Photodynamic Therapy

First 24 Hours

Expect:

  • Significant redness (like a sunburn)
  • Mild to moderate swelling
  • Possible crusting or scabbing beginning to form
  • Mild tenderness

Do:

  • Apply sunscreen (SPF 50+) every 2 hours if you go outside
  • Use a gentle, fragrance-free moisturizer
  • Avoid hot water, saunas, and intense exercise
  • Stay out of direct sunlight
  • Sleep with your head elevated

Don’t:

  • Apply makeup (wait at least 24 hours, ideally longer)
  • Pick or scratch at any crusting
  • Use harsh cleansers or exfoliants
  • Engage in activities that cause excessive sweating

Days 2–7

Expect:

  • Continued redness (peaks around day 2–3, then gradually improves)
  • Peeling and crusting as damaged cells shed
  • Possible temporary darkening of treated lesions (they appear darker before shedding)
  • Mild itching as skin heals

Do:

  • Continue strict sun protection (SPF 50+, reapply frequently)
  • Gently cleanse with lukewarm water and a soft cloth
  • Apply moisturizer multiple times daily
  • Use gentle, fragrance-free skincare products only
  • If itching occurs, apply hydrocortisone cream (1%) or ask your dermatologist for recommendations

Don’t:

  • Wear makeup (especially during days 2–5 when peeling is heaviest)
  • Swim or submerge the area in water
  • Use hot water or exfoliating products
  • Pick at peeling skin
  • Exercise intensely or sweat heavily

Weeks 2–4

Expect:

  • Significant improvement in redness
  • Most crusting resolved
  • Skin texture becoming smoother
  • Continued sun sensitivity
  • Treated lesions may disappear completely, or slight discoloration may remain temporarily

Do:

  • Continue sunscreen use (SPF 50+) for at least 4 weeks
  • Maintain gentle skincare
  • Consider makeup after day 7–10 if skin is healed
  • Resume normal activities gradually
  • Stay hydrated and eat antioxidant-rich foods to support healing

When Results Become Visible

Weeks 2–4: Initial improvement in redness and crusting; lesions begin to resolve Weeks 4–8: Maximum improvement becomes apparent; skin texture significantly improved Months 2–3: Final results stabilize; full benefit of treatment visible

Some patients benefit from a second PDT session 4–12 weeks after the first treatment for optimal results, especially for extensive actinic keratosis.

Photodynamic Therapy Results

What PDT Achieves

Reduction of Actinic Keratoses Clinical studies show clearance rates of 60–90% of treated actinic keratosis lesions after a single PDT session. Many patients see 75%+ improvement or complete clearance.

Improvement in Skin Tone Beyond targeting precancerous lesions, PDT promotes collagen remodeling and reduces inflammation, resulting in:

  • More even pigmentation
  • Reduced redness and blotchiness
  • Improved skin radiance

Reduction of Sun Damage Fine lines, roughness, and textural irregularities improve as the skin’s protective barrier strengthens and collagen production increases.

Acne Improvement Patients with acne often see 50–80% reduction in active breakouts, with additional improvements in post-inflammatory hyperpigmentation and overall skin clarity.

Long-Term Prevention Benefits Perhaps most importantly, PDT isn’t just about treating existing lesions—it reduces the risk of new actinic keratoses and skin cancer by addressing subclinical damage you can’t see yet. This preventive benefit often continues for months or years after treatment.

Longevity of Results Results typically last 12–24 months, though this varies based on individual sun exposure, skin type, and overall sun protection habits. Many dermatologists recommend annual or semi-annual maintenance PDT sessions for patients with extensive sun damage to prevent lesion recurrence.

Side Effects

Common Side Effects

Most side effects resolve within 2–4 weeks and are considered normal, expected reactions to treatment:

Redness Nearly all patients experience redness, ranging from mild to pronounced. This typically peaks 24–48 hours after treatment and gradually improves. It may persist for 1–2 weeks.

Swelling (Edema) Mild to moderate swelling is common, especially on the face. This peaks around 24–48 hours and usually resolves by day 7.

Peeling As damaged skin cells shed, you’ll experience peeling and flaking. This is a sign that PDT is working. Use gentle moisturizers and avoid picking at skin.

Crusting Treated lesions often develop a thin crust as they heal. Don’t pick—allow crusts to fall off naturally.

Tenderness The treated area may feel tender or sensitive for several days, similar to a sunburn.

Less Common Risks

While rare, these side effects can occur:

Infection With proper wound care and sun protection, infection is very rare. Signs include increasing warmth, pus, or spreading redness. Contact your dermatologist immediately if these occur.

Hyperpigmentation Some patients, especially those with darker skin types, may develop temporary darkening of the treated area. This usually resolves within weeks to months.

Hypopigmentation Conversely, some areas may become temporarily lighter. Again, this is typically temporary.

Temporary Photosensitivity For 24–48 hours after treatment, your skin is more sensitive to light. Strict sun avoidance and SPF 50+ sunscreen are essential.

Persistent Redness (Rare) In uncommon cases, redness may persist longer than typical. Your dermatologist can recommend additional treatments if this occurs.

Medicare & National Treatment Statistics

PDT has experienced tremendous growth across the United States, reflecting increasing recognition of its efficacy and safety. Understanding these trends underscores why dermatologists increasingly recommend PDT as a first-line treatment for actinic keratosis and sun damage.

Growing Use Across the U.S.

According to Medicare data, PDT utilization has grown substantially:

  • 152,310 Medicare PDT procedures were performed in 2019
  • This represented a 5.9% increase compared to 2018
  • Over the past decade, PDT has become increasingly common across all geographic regions

Increasing Demand

The dramatic rise in PDT use reflects both awareness and proven outcomes:

  • PDT procedures increased from 182 to 205 per 100,000 Medicare Part B beneficiaries between 2012 and 2016
  • ALA administration increased from 209 to 234 per 100,000 beneficiaries over the same period
  • This trend has continued upward, indicating growing trust in the treatment

Medicare Investment

Medicare’s investment in PDT demonstrates the procedure’s value in skin cancer prevention:

  • Combined Medicare spending for PDT and ALA increased 45% (inflation-adjusted) from 2012 to 2016
  • Spending grew from approximately $45,512 to $76,028 per 100,000 Medicare enrollees
  • This investment reflects the volume of procedures and their recognized value in preventing skin cancer

Geographic Trends

PDT utilization is not uniform across the country:

  • Highest utilization: Pacific states, Mountain states, and South Atlantic regions
  • Nearly 91% of PDT procedures occur in metropolitan areas
  • This geographic variation likely reflects both dermatologist availability and awareness of PDT among healthcare providers

Medicare Coverage

Good news for Medicare beneficiaries:

  • Medicare covers PDT for actinic keratosis treatment
  • No restriction based on the number of lesions treated
  • National Coverage Determination has supported PDT coverage since 2001
  • This consistent coverage demonstrates Medicare’s confidence in PDT as an evidence-based treatment

Why Early Treatment Matters

The Cost of Waiting

If you have actinic keratosis, early intervention isn’t just cosmetically important—it’s medically critical. Here’s what the HHS-supported data shows:

Frequency of Treatment Needs Patients with actinic keratosis average approximately 3.7 dermatology encounters over 4.4 years. This means if you have AK, you’re likely to need ongoing care without early, comprehensive treatment.

Progression to Skin Cancer The progression risk of untreated actinic keratosis is significant:

  • 6.3% risk of progression to invasive squamous cell carcinoma within one year
  • 28.5% risk of progression within five years

These statistics underscore that actinic keratosis is not just a cosmetic concern—it’s a precancerous condition requiring intervention.

Why Dermatologists Recommend Early, Comprehensive Treatment

Rather than waiting for lesions to develop and then treating them individually with topical creams (which takes weeks and only targets the lesion you can see), dermatologists recommend proactive field therapy with PDT because:

  1. Addresses visible and subclinical damage – PDT treats lesions you can see plus field damage you can’t, reducing future lesion development
  2. Faster results – One PDT session treats multiple lesions simultaneously, whereas topical treatments take 4–12 weeks
  3. Lower recurrence – Early PDT has lower recurrence rates than waiting to treat with topical options
  4. Cancer prevention – Comprehensive field therapy addresses the root cause of actinic keratosis (sun damage), not just individual lesions
  5. Fewer office visits – One PDT session may prevent the need for multiple future visits for new lesions

The bottom line: If you have actinic keratosis or extensive sun damage, delaying treatment increases your risk of skin cancer development and skin cancer burden over time. Early intervention with PDT is the most effective strategy for long-term skin health.

PDT vs. Other Treatments

Not all actinic keratosis treatments are created equal. Here’s how PDT compares to other common options:

TreatmentBest ForDowntimeCosmetic ResultScarringTimeline
Photodynamic TherapyMultiple AKs, field therapy, cosmetic improvementLow (1–2 weeks)ExcellentRareResults visible in weeks
CryotherapySingle or few lesionsLow (days)GoodPossible (white spots)Immediate, but limited cosmetic benefit

Chemical PeelCosmetic resurfacing, superficial damageModerate (1–2 weeks)GoodRareImmediate improvement
Laser TherapySun damage, deeper lesionsModerate (1–2 weeks)ExcellentRareResults develop over weeks

Why PDT Often Wins for Comprehensive Treatment

For treating multiple actinic keratoses: PDT surpasses individual cryotherapy because one session treats dozens or hundreds of lesions.

For combining treatment with cosmetic improvement: PDT outperforms topical creams because it improves skin tone, texture, and appearance—not just lesion clearance.

For preventing future lesions: PDT’s field therapy approach addresses subclinical damage, reducing the development of new lesions better than treatments targeting only visible lesions.

For faster results: PDT produces visible improvement in weeks, whereas topical treatments take 4–12 weeks.

Frequently Asked Questions

Does Photodynamic Therapy Hurt?

PDT is generally well-tolerated, though not pain-free. Most patients describe a stinging or burning sensation during light activation, similar to a sunburn developing. Pain is usually mild to moderate and manageable.

  • With daylight PDT, discomfort is minimal.
  • With blue light, discomfort is moderate but brief.
  • With red light, discomfort is typically mild.

You can discuss pain management options with your dermatologist before treatment. Some patients benefit from topical anesthetics or the option to take breaks during the light application.

How Long Does PDT Take?

The complete appointment, including preparation, medication application, incubation, light activation, and post-treatment care, typically takes 45–60 minutes. The light activation itself (the most time-intensive step) lasts about 15–20 minutes.

How Many Treatments Are Needed?

For actinic keratosis: Most patients see significant improvement after a single PDT session. Some may benefit from a second session 4–12 weeks later for optimal clearance.

For acne: Typically 1–3 sessions spaced 2–4 weeks apart yield the best results.

For maintenance/prevention: Many dermatologists recommend annual or semi-annual PDT sessions to prevent new lesion development, especially for patients with extensive sun damage.

Your dermatologist will recommend a treatment schedule based on your specific condition.

Is PDT Covered by Medicare?

Yes. Medicare covers PDT for actinic keratosis treatment with no restriction based on the number of lesions. Coverage has been in place since 2001. Most private insurance also covers PDT, though specific coverage varies by plan. We recommend checking with your insurance provider before scheduling your consultation at Campbell Dermatology.

How Long Is Recovery?

Most patients return to normal activities immediately with proper sun protection. However:

  • Visible redness lasts 1–2 weeks
  • Crusting and peeling peak around days 2–7
  • Complete healing occurs within 4 weeks
  • Makeup can usually be worn after 7–10 days if skin has healed
  • Exercise and sweating should be avoided for the first 24–48 hours

Can PDT Prevent Skin Cancer?

While PDT doesn’t eliminate all future skin cancer risk, it significantly reduces the risk of developing new actinic keratosis and squamous cell carcinoma by treating both visible and subclinical sun damage. Combined with ongoing sun protection, PDT is one of the most effective preventive strategies available.

Is PDT Better Than Cryotherapy?

It depends on your specific situation:

  • For single lesions: Cryotherapy is quick and effective
  • For multiple lesions: PDT is superior because it treats dozens at once
  • For cosmetic improvement: PDT produces better overall skin quality improvements
  • For recurrence prevention: PDT has lower recurrence rates

Most dermatologists consider PDT the gold standard for treating extensive actinic keratosis and sun damage.

Can PDT Treat Acne?

Yes. PDT is effective for moderate to severe acne because:

  • Blue light kills acne-causing bacteria
  • PDT reduces sebaceous gland activity and oil production
  • Reduces inflammation and redness
  • Improves post-inflammatory hyperpigmentation

Results typically improve after 1–3 sessions. It’s particularly effective for patients who don’t tolerate or haven’t responded to topical acne treatments or antibiotics.

Can I Wear Makeup After PDT?

Not immediately. Most dermatologists recommend waiting at least 7–10 days before wearing makeup, once the skin has largely healed and crusting has resolved. Using makeup too early can irritate healing skin or trap bacteria, increasing infection risk.

When you do resume makeup, use only clean brushes and fragrance-free, non-comedogenic products.

When Can I Return to Work?

Immediately, with proper sun protection. PDT doesn’t require downtime in the sense of needing bed rest. You can return to office work or non-physical activities right away.

However, if your job involves outdoor work, heavy sweating, or close-up customer interaction where your redness might be noticeable, you may want to schedule PDT accordingly (perhaps before a weekend or during a period of less demanding work).

Is PDT Safe?

Yes. PDT has been used for over 20 years with an excellent safety profile. FDA-approved photosensitizing medications and light devices are manufactured to rigorous standards. Serious complications are extremely rare.

Minor side effects (redness, swelling, peeling) are expected and temporary. Proper sun protection and post-treatment care minimize even these minor effects.

How Long Do Results Last?

Results vary but typically last 12–24 months. Longevity depends on:

  • Individual sun exposure after treatment
  • Skin type and sun sensitivity
  • Overall sun protection habits
  • Presence of extensive subclinical damage

Maintenance PDT: Many dermatologists recommend annual or semi-annual maintenance sessions for patients with extensive sun damage to prevent new lesion development and maintain cosmetic improvements.
