Retinol or Vitamin A is an essential nutrient for cell growth and differentiation.
Retinol reduces transepidermal water loss (TEWL), thus increasing the hydration and elasticity of the skin and preventing rough skin resulting from exposure to UV radiation. It also:
Increases the thickness of the epidermis and reduces the number and depth of wrinkles and expression lines.
Inhibits collagenase, increasing the production of collagen fibronectin and hyaluronic acid.
Its use results in smoother, softer, firmer skin.
Thanks to its firming and antioxidant capacity, Retinol is contained in products such as Krono-Age Serum and Expression Gel.
