Vitamin A promotes epidermal cell turnover and stimulates collagen synthesis, helping to reduce fine lines and improve skin texture. It works by binding to retinoid receptors in skin cells, triggering regeneration and renewal. Different forms (retinol, retinyl esters, retinaldehyde) vary in potency and conversion efficiency to retinoic acid.
