A chemical solution applied to your skin before light therapies such as BLU-U® and FotoFacial | Intense Pulsed Light | IPL® makes targeted tissue more light sensitive, so each treatment is more effective and fewer treatments are required. We typically use aminolevulinic acid (ALA) as the photosensitizing agent.
Photodynamic Therapy has been effective in the treatment of actinic keratosis (pre-cancerous spots), some types of skin cancer, sun damaged skin, acne, and oily skin with sebaceous gland enlargement.
The number of treatments necessary and treatment intervals will vary depending on the condition being treated.
Retin-A and similar topical creams (Renova, Retinol, Differin, Avita, Tazorac) should be discontinued several days prior to PDT. Avoid sun exposure for two days following PDT, because your skin will still be very sensitive to light. If the Intense Pulsed Light machine is used to provide the light source, you must avoid the sun for at least one week prior to treatment as well.
