  Anti-Aging Products: An Industry Built on False Promises? The anti-aging product industry has been on a steep rise in the past decade. With more and more consumers looking for ways to slow down or even reverse the physical signs of aging, companies have rushed to provide a wide array of purported "anti-aging" creams, serums, supplements and procedures. However, many experts argue that most anti-aging claims are simply not supported by scientific evidence. Let's take a deeper look at the science behind popular  anti-aging products  and procedures. Retinol and Other Topical Creams One of the most common active ingredients found in anti-aging creams is retinol. Retinol, a form of vitamin A, has been shown to increase collagen production and cell turnover which can reduce the appearance of fine lines and wrinkles over time with consistent use. However, most studies have only found these benefits for topical retinol concentrations of 0.5% or higher. Many popular anti-aging c...
