A Reliable Vitamin A Cream Might Be The Most Effective Staple In Your Skin Care Regiment

Dr. J. Matthew Knight, dermatologist of the Knight Dermatology Institute, says “There’s nothing more effective than Vitamin-A based creams when it comes to the treatment/prevention of wrinkles, fine-lines, age spots, and photo aging… Recent studies show that  OTC retinol at higher strengths may be almost as effective as prescription Retin-A, but with lower cost and less irritation.” About Face Organic Vitamin A Night Cream contains two percent retinol, and it’s gentle, non-greasy, and extremely nourishing. “The key, though,” says Dr. Knight, “is consistency — it should be used every night for a lifetime.”
