Photodynamic therapy is a highly successful method of treating localized rough pigmented skin patches, pre-cancerous actinic keratoses (AKs), wrinkling, enlarged pores. It is also a well-known solution for resistant acne.
The treatment consists of two stages, the first is a cream application. The ingredients of this cream are readily absorbed by rapidly growing, photodamaged skin cells, actinic keratoses, sebaceous glands and even hair follicles. It is this selective absorption that makes PDT such an effective treatment for overall skin improvement. The second stage of the treatment 10 to 30 minutes later, involves shining a pure light on the treatment area to activate the cream. It is only when both this specific cream and the pure light are combined that they have a profound effect on the skin. The cream undergoes a chemical change due to the light exposure that causes it to release a powerful oxygen molecule which destroys the damaged skin cells on the surface of the skin and in the hair follicle and pores.
The preparation of the skin, exposure time, wavelength and light source used to activate the medicated cream are dependent upon the area of the body or face being treated, as well as the condition.
After treatment has happened skin will be red, areas of pigmentation will darken and peel and some individuals may experience swelling especially around the lip and/or eye areas. These symptoms subside after around 2-7 days exposing fresh healthy underlying skin. Skin continues to improve in both texture and tone, pore size reduces and the oil flow of sebaceous glands is reduced resulting in less pore blockage.
To achieve maximum improvement, a series of approximately three treatments at 2-4 week intervals are most effective. Some patients with actinic keratoses will achieve results in just one treatment.
