There is no one such serum that does everything. What they show on TV or while promoting brands is all a marketing gimmick. Skin care is a process whether your skin is sensitive or acne prone or dry or wrinkled. Plus, life style needs to be very healthy to keep your skin wrinkle free and acne free. Visit a dermatologist. The doctor will examine your skin and not only suggest you the right creams but guide you on what's good for you and what's not.
