Many people know that overexposure to sunshine can result in sun damage to the skin. In most cases, this damage can simply appear as harmless spots. In other cases, however, the spots can become pre-cancerous health risks. A treatment for Sun Damage Pittsburgh is available at Prizant Dermatology in Pittsburgh, PA, it is what we call the Photodynamic Therapy (PDT) for at-risk skin and Actinic Keratoses––precancerous lesions that may become serious if not treated.
Actinic Keratoses are precancerous skin growths. They appear when cells in the outer layer of the skin become damaged by the sun’s rays. When these growths show up, they often appear on the face, forehead, or neck and are usually not painful, it is serious that sun damages skin. Although there is a low likelihood that any one particular spot will become cancerous, a patient with several growths may run a higher risk for skin cancer. As a result, it is wise to have these growths removed if possible. At Prizant Dermatology, we offer Photodynamic Therapy as a comfortable and effective way to treat this condition.
In the past, Actinic Keratoses were often removed by using a surgical knife or liquid nitrogen. This could be very painful and sometimes even lead to scarring. Fortunately, we now have PDT, which is a much more modern approach to correcting Actinic Keratoses. This PDT procedure is often called a “field treatment,” as it can cover an entire area (or field) at once rather than dealing with each growth individually.
Photodynamic Therapy is FDA-approved for the treatment of Actinic Keratoses. It is a multi-step approach that uses light treatment for sun damaged skin to neutralize the growths and provide comprehensive, effective results, although individual results and treatment plans can vary.
During light treatment for sun damaged skin, a liquid substance is applied that will become absorbed by the skin. When the substance combines with sun-damaged cells, it causes them to become extremely sensitive to light. After the damaged cells have been primed for treatment, a special device exposes the damaged cells to a special wavelength of light. In the process, the damaged cells are killed by the light treatment, but healthy cells remain unharmed. After the damaged cells have undergone light therapy, the body should naturally begin to remove them from your system before they can become a cancer threat.
For patients who have extensive sun damage, multiple sessions may be recommended. In other cases, our professional may recommend a periodic maintenance treatment, especially if your skin is frequently exposed to the sun.
Unlike surgical removal or freezing with liquid nitrogen, PDT does not cut or damage surrounding tissue. This makes it a gentler, less painful option.
Photodynamic therapy is FDA-approved for Actinic Keratoses, offering a safe and proven way to treat precancerous lesions before they develop into something more serious.
PDT works as a “field treatment,” targeting not only visible growths but also underlying sun-damaged skin in the surrounding area. This helps prevent new lesions from forming.
Recovery is typically quick, with only temporary redness, flaking, or sensitivity. Most patients can resume their normal activities immediately.
In addition to treating precancerous cells, PDT often improves the overall look of the skin, creating a smoother, more even texture.
Because the treatment is non-invasive, there is far less risk of scarring compared to traditional surgical methods.
By destroying precancerous cells, PDT reduces the risk of developing squamous cell carcinoma and other forms of skin cancer.
Sessions can be tailored to the size of the treatment area and the severity of the sun damage, making it flexible for each patient’s needs.
If new growths appear over time, PDT can be safely repeated, providing patients with a long-term option for managing ongoing sun damage.
Photodynamic Therapy (PDT) is a modern, non-invasive treatment that targets both visible and hidden sun damage while reducing the risk of precancerous lesions developing into skin cancer. Unlike traditional approaches that focus only on individual spots, PDT works across a broader area and often improves skin tone and texture as an added benefit. Here’s how it compares to other common treatments for sun damage and Actinic Keratoses:
Because Photodynamic Therapy is a non-invasive, FDA-approved treatment, the risks are generally low, and the side effects are mild compared to surgical or freezing methods. Unlike cryotherapy, which may leave scars, or surgical excision, which can be painful, PDT works locally on damaged skin cells with minimal trauma to surrounding tissue.
Possible side effects include:
These effects usually resolve within one to two weeks and rarely interfere with daily activities. With no cutting or invasive techniques involved, the chance of complications is very low. At Prizant Dermatology, Dr. Tracy Prizant’s expertise ensures that your treatment is delivered safely, comfortably, and with careful attention to minimizing risks.
Your Photodynamic Therapy treatment will be personalized to your skin’s needs, but here’s a general overview of what the process involves:
Every PDT treatment at Prizant Dermatology begins with a thorough consultation. Dr. Tracy Prizant or a member of our team will examine your skin, review your medical history, and discuss any areas of concern. Together, we’ll determine if Photodynamic Therapy is the best option for treating your sun damage and Actinic Keratoses, and create a treatment plan tailored to your skin health.
On the day of your appointment, the treatment area will be cleansed and prepared. A light-sensitizing solution is then applied and allowed to absorb into the skin. Once the solution has properly absorbed, a specialized light is directed onto the area, activating the solution and destroying precancerous cells while leaving healthy tissue unharmed.
The length of your session depends on the size of the treatment area, but most patients can expect the appointment to last one to two hours, including the absorption period. The light exposure itself typically lasts only a few minutes.
After your session, your skin may appear red or tender, similar to a mild sunburn. Some peeling, crusting, or flaking is also normal as damaged skin cells shed. These effects usually fade within a week or two.
Most patients can resume normal daily activities quickly, with only a brief period of sensitivity. With proper aftercare, your skin will gradually reveal the benefits of treatment — healthier, clearer skin and a reduced risk of precancerous lesions developing into skin cancer.
One of the biggest benefits of Photodynamic Therapy is that it involves minimal downtime. After your session, the treated skin may feel tender, appear red, or begin to flake, similar to a mild sunburn. These effects are temporary and usually resolve within one to two weeks as the body naturally sheds damaged cells.
You’ll be advised to avoid direct sunlight for at least 48 hours, use a broad-spectrum sunscreen daily, and apply gentle moisturizers to support the healing process. Most patients can return to work and normal activities immediately, making PDT a convenient option for treating precancerous lesions without disrupting their daily lives.
To help your treatment go as smoothly as possible, a few simple steps can prepare your skin and maximize results:
You don’t need to bring anything special with you, but it’s important to follow your provider’s guidance and ask any questions before your session begins. At Prizant Dermatology, our team will walk you through every step, ensuring you feel informed, comfortable, and confident in your care.
Not everyone with sun damage or Actinic Keratoses will need Photodynamic Therapy, but for many patients, it offers a safe and effective solution. You may be a good candidate if you:
During your consultation, we’ll also review your medical history and evaluate your skin in detail to ensure PDT is the safest and most effective option for you.
The cost of Photodynamic Therapy can vary based on the size of the treatment area, the number of sessions required, and whether the procedure is performed for medical or cosmetic reasons. When used to treat Actinic Keratoses, PDT is often covered by insurance since it is an FDA-approved medical treatment for precancerous lesions.
For patients seeking PDT for cosmetic skin improvements, coverage may not apply, and out-of-pocket costs will depend on the treatment plan recommended by Dr. Prizant. During your consultation, our team will provide a clear estimate and review your insurance benefits so you know exactly what to expect before starting treatment.
Discomfort during PDT is usually minimal. Some patients feel a warming or tingling sensation as the light activates the medication, but this is generally short-lived. Cooling fans or other comfort measures can be used during treatment to alleviate any discomfort or sensitivity.
The number of sessions depends on the extent of sun damage or the number of lesions you have. Some patients respond well to a single session, while others may require a series for full clearance. Your dermatologist will monitor your skin over time and recommend a schedule that ensures the best long-term protection.
Many patients enjoy clear, healthy-looking skin for months after treatment. However, since sun exposure can cause new damage over time, follow-up treatments may be needed. Consistent sun protection plays a major role in prolonging your results.
It’s usually best to avoid makeup for the first day or two after your session, when the skin is most sensitive. Once redness and tenderness begin to subside, light mineral-based makeup is generally safe. Our team will provide guidance on when it’s safe to return to your usual skincare and cosmetic routines.
Within days to weeks, treated lesions often crust, flake, or fade as the body sheds damaged cells. Your dermatologist will check your progress at follow-up visits and may recommend additional sessions if needed. Improvement is usually noticeable both medically and cosmetically once the healing process is complete.
