PDT is a new and exciting treatment which involves the application of a photosensitizing medication to the skin followed by exposure to a specialized light source, either a laser, intense pulse light machine, or a special blue light lamp. The light source activates the medication for the desired effect. This technique has recently gained FDA approval for the treatment of actinic keratoses (“pre-cancers”) and, in some instances, skin cancers. Treatment of skin cancers with PDT of course also means an improved cosmetic outcome that leaves virtually no scars since no surgery is involved.
PDT not only clears pre-cancerous lesions, but may serve to prevent the occurrence of new pre-cancers and skin cancers. PDT treatments are quite versatile and applications are being expanded to include treatment of acne, rosacea, brown spots, broken capillaries, and even enlarged oil glands. The combination of skin cancer prevention and cosmetic enhancement makes PDT an ideal treatment for the right candidate.
