Precancerous Lesions / Actinic Keratosis treatment with Photodynamic Therapy

The blue light is used successfully in combination with a light-activated medicine for the treatment of precancerous growths called actinic keratosis (AK), a common precancerous skin lesion caused by excessive sun exposure – especially in people with fair skin. Available in only a few South Bay practices, this treatment uses a light-activated medication combined with LED light to treat more widespread precancers and sun damage.

The area is treated with a topical clear gel, which is activated by the blue light. This is an alternative to liquid nitrogen freezing, which may cause white spots, or topical chemotherapy, which results in more than 4 weeks of redness. Photodynamic Therapy (PDT) provides the same benefit – smoother, healthier skin – with, at worst, a sunburn-like reaction and some redness and peeling for 2-3 days. After a few days of healing time, the treated area is smooth, and the precancers are resolved by 90% or more.



PDT can also be done primarily for cosmetic benefits. If you have facial redness, sun-induced broken blood vessels, or rough, sun-damaged skin, your complexion should improve from the light-activated medicine used in combination with the pulsed dye laser. The result will be softer, smoother, more even-toned skin – younger looking and radiant.
