For the first time, science proves that daily sunscreen use significantly slows skin aging, even in middle-aged men and women. Sunscreen and antioxidants have long been advocated to prevent skin aging, but to date, there has been no scientific evidence of their effectiveness.
Researchers measured photo-aging of 903 participants younger than 55 to determine whether regular use of sunscreen would slow skin aging compared with discretionary application. At the same time, researchers tested the anti-aging effects of beta-carotene supplements compared to placebo.
