Which vitamin is good for antiaging?

Several vitamins are excellent for antiaging. Vitamin C is one of the most effective, as it boosts collagen production, brightens skin, and protects against free radical damage. Vitamin E works as an antioxidant and helps repair skin. Vitamin A (retinoids/retinol) is the gold standard for reducing wrinkles and improving cell turnover. Vitamin D supports skin cell growth and repair. B vitamins, especially niacinamide (B3), improve skin barrier function and reduce inflammation. Vitamin K helps with dark circles and bruising. For best results, get these vitamins through a balanced diet and use topical formulations in your skincare routine.
