What are the best anti-aging products to use on my face?

Vitamin A. Vitamin a (retinoids) are the mainstay for stimulating new collagen growth. Vitamin c is necessary for collagen production. Vitamin e is a powerful antioxidant to repair and prevent damage from sun and pollution. Other products are available, but these are the ones proven to work. Look for high quality a, c and e.
Retinoids. Retinoids, vitamin c, vitamin e, and sunscreen-- which is the most important one of all. See your doctor, as these may not be appropriate for everyone.
