Wrinkles are caused primarily from a breakdown of collagen. Therefore, preventing collagen breakdown is the most effective treatment for wrinkles. Prevention is best obtained by reducing sun exposure, reducing stress, eating a well-balanced diet, and doing low-impact exercise. Dietary supplements and foods high in Vitamin A will help stimulate new collagen. Also, an effective skin care regimen combined with professional treatments can help initiate collagen synthesis and keep the skin looking and feeling smooth.
