Photodynamic therapy is an advanced 2-step treatment for pre-cancer skin conditions - specifically rough, scaly patches on the skin caused by excessive sun exposure known as actinic keratoses (AKs). The system is unique because it's the only one that uses light to destroy these precancerous lesions.
In the first step of photodynamic therapy, Dr. Jao will apply an acid that occurs naturally in the body to individual AKs on your skin. This makes the AKs more sensitive to light.
After waiting an hour, Dr. Jao will expose the AKs to a special blue light which destroys the lesions. Because the first step makes the treated areas more sensitive to light, it is important to avoid bright light during the time between the first and second steps.
During the blue light therapy, you may feel a stinging or burning sensation in the treated areas. This generally improves immediately after treatment and ends within 24 hours.
