In a recent article in Dermatology Times the following statement attracted our attention:
“Among U.S. medical applications, photodynamic therapy (PDT) ranks as probably the most important underused laser technology, says Jill Waibel, M.D., a dermatologist in private practice at Palm Beach Esthetic Dermatology & Laser Center, West Palm Beach, Fla., and a volunteer faculty member with the University of Miami Department of Dermatology.”

Our quick study of the issue revealed similar results. PDT has been widely adopted in Europe, where phyicians use PDT for skin cancer, ovarian cancer and other cancers. PDT has been known to prevent skin cancer and to successfully treat pre-cancers of the skin. The U.S. healthcare system spends billions of dollars annually to freeze actinic keratoses (AKs) or to excise skin cancers only after they’ve developed.

Additional applications for PDT include treating actinic chelitis, basal cell carcinoma, nevus syndrome, disseminated porokeratosis, acne keloidalis nuchae, pseudofolliculitis barbae and hidradenitis suppurativa.

Blue light low power light is typically used in PDT. This type of lasers is not the main focus of our coverage, but we thought it is worth mentioning since this procedure is borderline with aesthetic lasers.
