For the last decade or so, retinoids have been considered one of the most effective topical treatments for improving skin turnover. But between retinoids, retinol, and Retin-A, how do you know what to look for? The term “retinoid” describes a family of ingredients that includes both Retin-A and retinol. Retinoids are a class of ingredients chemically related to vitamin A. These diverse compounds naturally occur everywhere in our bodies and are vital to internal processes like immune function and tissue repair. When looking at skincare products, it’s important to remember that “retinoid” is an umbrella term and doesn’t specify the type of retinoid compound in the formula. The only type of retinoid that your skin is able to process immediately is retinoic acid. All other forms of retinoids have to be converted by skin enzymes into retinoic acid before the skin is able to use it. A few years ago, a friend told me both she and her mother had discovered the secret to anti-aging — Retin-A. Now that I'm in the business of beauty and skin care, I've done a ton of research on anti-aging products and what I've found is that dermatologists agree on one thing: The only anti-ager on the market that has proven again and again to reduce fine lines and wrinkles is tretinoin, a derivative of Vitamin A. "Honey," she said, while taking a drag on her cigarette, "This is WHY I have flawless skin."My friend was about a few years older than me — in her mid-30s — and she wasn't the first flawless-skinned woman I would come to know whose dermatologist prescribed a Retin-A (or tretoinin) as a way to combat fine lines and wrinkles. I had always thought of Retin-A as something found only in the medicine cabinets of pimply teens. Although Retin-A was the first and most famous Vitamin A derivative used for anti-aging, other Vitamin A products have since popped up including Tazorac, Renova, and Differin. A host of over-the-counter medications containing lower doses of Vitamin A have also hit the market. While Retin-A remains a medication to treat acne, all of these new products were created specifically to fight wrinkles. Collagen is the key to healthy skin that tends to age well.
