A PhotoDynamic Therapy (PDT) method is presented for cosmetic rejuvenation, which is exemplified by a two phase approach for treating facial and neck skin aging while minimizing damage to the underlying region of skin being treated. To obtain best results a combination of treatments are used. This includes applying photosensitizer and light energy for stimulating the collagen within the skin, thereby restoring the elasticity of skin. The treatment procedures take about six weeks consisting of impair (damage) and repair (recovery) sessions involving skin preparation by peeling, skin detoxification, application and distribution of photosensitizer to the skin, irradiation of pre-sensitized skin followed by removal of mask. Results of long lasting improvement, especially in comparison with most cosmetic treatments, are obtained upon completion of the series, with marked changes being observed after individual sessions, which provide added incentive to complete a treatment program. These results eliminate the need for repetitive treatments after the six week series, unlike most current approaches which require repeat sessions semi-annually or annually.
