DDF

Doctor's Dermatologic Formula (DDF) has developed skincare based on in-office procedures that work with your skin's physiology—and without a prescription. The brainchild of world-renowned dermatologist, Dr. Howard Sobel and his sister Elaine Linker, DDF developed its legendary mantra — Cleanse. Protect. Treat. — focusing on anti-aging (preventative and restorative), acne, hyper pigmentation, rosacea, sun protection, and sensitive-allergic conditions.
