Rx anti aging 101

Retinoids work by prompting surface skin cells to turn over and die rapidly, making way for new cell growth underneath.For brown spots that give the skin an uneven tone, retinoids slough them off and curb the production of melanin, a darker pigment. Retinoids minimize the appearance of wrinkles, bolster skin's thickness and elasticity, slow the breakdown of collagen (which helps keep skin firm), and lighten brown spots caused by sun exposure.For aging skin, dermatologists like to prescribe tretinoin and retinoic acid (Retin-A, Renova, Refissa) that is "100 times" as potent as the retinol-containing products sold without prescription, Jacob says.They hamper the breakdown of collagen and thicken the deeper layer of skin where wrinkles get their start, Jacob says.an exclusive blend of proven age-fighting antioxidants (Vitamins A, C and E) has been added to combat the damaging effects caused by environmental insults.All products are paraben free, natural and ideal for treating all skin types and ethnicities.It's not true, Farris says, that retinoids thin the skin.We believe in quality products that are gentle, yet effective."Tretinoin works better because it has a stronger capability of preventing the breakdown of collagen," she says.
