Besides, more recently, PDT has been used, widely and with great success, for many off-label diseases and in cosmetic dermatology, especially on photorejuvenation, therefore further and larger prospective studies with long-term follow-up are required to verify its efficacy and safety in treating these condition. The treatment of ageing skin remains a very hot topic, and many systems have been reported as having varying degrees of success. Nowadays our experience and literature data show how topical PDT can be considered a new non-invasive device for the treatment o photoaging skin with no/minimal side effects and able to bridge the world of medical and cosmetic dermatologic surgery.展开更多
