Neutrogena Retinol Boost anti-aging cream delivers pure retinol to the skin's surface. It will fight all visible signs of aging . Its results are clinically proven. It is suitable for all skin types. It improves skin texture and evens out skin tone after just one week, reduces the appearance of fine lines and wrinkles in one month, and fades age spots in two months. 

Pure retinol is a form of vitamin A. It has many properties. It activates fibroblasts , skin cells responsible for producing collagen and elastin. Collagen is responsible for skin firmness and elastin for its elasticity. With age, the production of collagen and elastin declines, leading to a loss of density and suppleness and the appearance of wrinkles. Retinol also fights hyperpigmentation and prevents the appearance of new brown spots. Thus, wrinkles and fine lines as well as spots are reduced. Neutrogena 
has combined retinol with myrtle plant extract to enhance its effectiveness.

This cream contains glycerin and hyaluronic acid . Glycerin will form a film covering the skin, allowing it to preserve its hydration. This is what allows it to smooth and soften the skin. Hyaluronic acid is a powerfully hydrating molecule, capable of retaining a large quantity of water.
