When shopping for anti-aging products, it is best to look for ingredients and formulations that are backed by evidence-based science and clinical studies to support their claims, meaning the claims are made on the final formula and the studies are performed on human subjects vs. in-vitro (cell cultures or reconstructed skin). This helps sift through the hype and ensure that anti-aging benefits have been proven. Many ingredients may have powerful claims or supporters behind them, but it does not mean these ingredients have been proven effective when used on live skin, or even in your formula. With that said, some ingredients have been researched more than others and are backed by years of real life research. Vitamin C is one of the most effective and extensively studied antioxidants available in skin care today, it is favored by skin care professionals for its preventative and anti-aging benefits on skin. However, there are many different forms of vitamin C. For optimal free-radical protection, look for pure ascorbic acid (l-ascorbic acid) on the ingredient label. In addition to neutralising free radicals and preventing premature aging, l-ascorbic acid has anti-aging benefits that include improving the appearance of wrinkles and loss of firmness. Additional antioxidants that also provide prevention against premature aging and anti-aging benefits are
ferulic acid, vitamin E (in its alpha-tocopherol form),
is the essential anti-aging ingredient. It is a form of vitamin A, a retinoic acid, and has decades of research and proof behind its efficacy on sign of aging, such as fine lines and discolouration. Similar to vitamin C, there are many forms of retinol. For maximum anti-aging results, always look for”retinol” on a product’s list of ingredients. Other derivatives such as retinyl palmitate, retinyl acetate, and retinaldehyde are not as effective.
