Photodynamic therapy is a skin treatment that uses a light-activated solution and a special light to destroy damaged or abnormal cells. It is commonly used to treat sun damage, precancerous lesions like actinic keratosis, and certain skin conditions.

Photodynamic therapy most commonly treats actinic keratosis, sun-damaged skin, acne, and some superficial skin cancers, while also improving overall skin texture and tone.

Photodynamic therapy works by applying a light-sensitive solution to the skin and activating it with a medical light source. This reaction destroys damaged cells while leaving surrounding healthy tissue largely unaffected.

Good candidates are patients with sun damage, actinic keratosis, acne, or uneven skin tone who want a minimally invasive treatment to improve skin health and appearance.

Photodynamic therapy may not be recommended for people with photosensitivity disorders, certain medication sensitivities, or allergies to the treatment solution, and pregnant patients should discuss risks with their provider.

Preparation is simple and usually involves avoiding sun exposure, stopping certain skincare products, and arriving with clean skin on the day of treatment.

Photodynamic therapy usually takes about 75 minutes total, including about 60 minutes for the solution to absorb and around 15 minutes for the light treatment.

Most patients feel mild tingling, warmth, or a stinging sensation during the light activation phase, but the discomfort is temporary and generally well tolerated.

Yes, mild downtime is common. Patients may experience redness, swelling, and skin flaking for several days, with most healing occurring within one week.

Common side effects include temporary redness, swelling, peeling, sensitivity to light, and mild discomfort, which usually resolve as the skin heals.

Most patients recover within 7 to 10 days, although redness and mild peeling can occur for the first few days after treatment.

After treatment, patients should avoid direct sunlight for 48 hours, wear sunscreen, and follow post-treatment skincare instructions to support healing.

Many patients see improvement after one treatment, but some conditions may require a series of sessions spaced several weeks apart for optimal results.

Photodynamic therapy is highly effective for treating actinic keratosis and sun damage, while also improving overall skin clarity and reducing acne in many patients.

Photodynamic therapy typically costs $300 to $800 per session, depending on the treatment area, condition being treated, and the number of sessions required.

The cost depends on the size of the treatment area, severity of the condition, number of sessions needed, and whether additional treatments are combined.

Yes, follow-up visits help monitor healing and determine if additional treatments are needed to maintain results or fully treat the condition.

Yes, photodynamic therapy can often be combined with laser treatments, chemical peels, or other skin rejuvenation procedures to enhance results.

The main benefits include targeted treatment of damaged skin cells, minimal invasiveness, improved skin appearance, and relatively quick recovery compared to more aggressive procedures.
