Sun Habits Beat Serums

No serum protects you the way your daily sun habits do. Sunscreen is only step one. Reapply every couple of hours outdoors, because protection wears off as you sweat and rub your face. Seek shade at midday and wear a hat and sunglasses; the skin around your eyes is thin and ages first. These small habits, repeated for years, outdo any product promising to reverse sun damage after the fact.
