PDT and ALA Therapy is a treatment that combines Omnilux Red light with a photosensitizing solution ALA to improve sun damage, pre-cancerous cells (actinic keratosis), severe acne, numerous viral warts and sebaceous hyperplasia in a non-invasive, cosmetically enhancing way.
The photosensitizing solution is 20% aminolevulinic acid ALA. This is applied to the surface of the skin to be treated, where it is absorbed preferentially by abnormal or pre-cancerous skin cells as well as oil glands and pores, making these more sensitive to laser or light.
After the incubation period (the time the solution sits on the surface of the skin), Omnilux Red light source will be used to activate the solution. This combination therapy leads to a destruction or reduction of abnormal cells and excessive oil gland cells and results in healthier, smoother, and clearer skin. By applying ALA before the treatment, we can selectively target the cells we want to damage or destroy, leaving the others surrounding it intact and without harm. This will actually kill off pre-cancerous or sun damaged cells as well as reduces oil gland cell number, reducing the side of the glands.
After the treatment one must avoid sunlight and other intense light sources completely for 48 hours. The majority of people will have mild redness and minimal discomfort but about 5% will experience "sunburn" like reaction in which they are uncomfortable for 24 hours and the skin looks red and peeled for 2-3 days.
Less than 1% experiences a very severe reaction resulting in redness and peeling for 1 week and very rarely longer. This usually happens when there is severe sun damage with multiple Actinic Keratosis present.
Complete healing does take place even in these cases and no scarring has been reported. Avoidance of this reaction can be greatly enhanced by COMPLETELY AVOIDING ANY SUNLIGHT FOR 48 HOURS. If any exposure is necessary, covering up with scarves, hats, and thickly applying zinc oxide to the treated area is advised.
Pure zinc oxide should be applied to the treated area or it should be covered with clothes, hats, or scarves for 48 hours. Do not expose the area to sunlight even briefly during this time. You may experience slight redness and/or peeling. You may resume your normal skin care after the peeling stops or immediately if there is no peeling. Make up may be applied immediately after your treatment. Normal skincare can be resumed after 24 hours unless otherwise directed by your provider.
