For Wrinkles: Retinol (Vitamin A), Vitamin C
If you have fine lines, retinoids (which come from vitamin A) like retinol may make your skin smoother because they help your skin make more collagen. It’s easier on your skin than the prescription-strength version, tretinoin (Retin-A), which can dry your skin. Products with vitamin C may help take away fine lines, as well as help lessen the damage the sun does to your skin. That could help keep wrinkles away.
