A variety of medical concerns are now being treated with lasers and light sources. The advent of ALA-PDT has heralded a potentially new era for dermatologists and laser surgeons far beyond the treatment of AKs, BCCs, and SCCs. Now "photodynamic photorejuvenation" is a common term and photorejuvenation treatments are being enhanced with the use of ALA-PDT. Other entities, including acne vulgaris, hidradenitis suppurativa, and sebaceous gland hyperplasia are being treated with lasers, light sources, and ALA-PDT. Lasers and light sources are also being used to treat psoriasis vulgaris, vitiligo, and other hypopigmented disorders, including hypopigmented stretch marks. Lasers and light sources can now be used to treat both medical and cosmetic dermatologic conditions.
