Why Do All Dermatologists Use Tretinoin For Anti-Aging? by Why Do All Dermatologists Use Tretinoin For Anti-Aging?Ask any dermatologist what their number one skincare recommendation is to prevent and reduce signs of aging and (right after saying "wear SPF!") they'll all tell you to use tretinoin. In fact, 10/10 of dermatologists use tretinoin themselves for overall healthier skin. Tretinoin is not only the single most studied medication for skincare out there—it's also the only drug approved by the FDA for anti-aging. Unlike other skincare products that make bold claims, there are thousands of studies done by dermatologists that prove tretinoin increases collagen in the skin to reduce fine lines and wrinkles, speed cell turnover to even out and brighten the skin tone, and smooth out texture by unclogging pores.Tretinoin is stronger, works faster, and is more powerful than any over-the-counter retinoid. In fact, the lowest Rx concentration can be 20 times stronger than the highest amount allowed by the FDA in drugstore products. Tretinoin works by speeding up the rate at which your body replaces skin cells, stimulating collagen production, and exfoliating the top layers of skin to reveal, fresher younger-looking skin underneath.Source: A comparative study of the effects of retinol and retinoic acid on histological, molecular, and clinical properties of human skin (Journal of Cosmetic Dermatology - 18 Nov 2015) All dermatologists recommend tretinoin for anyone over thirty to start preventing the visible signs of aging. When you stick with tretinoin, you may notice results in as little as four weeks. It's extremely important to always wear SPF all the time, but even more so if you are using tretinoin to get the full benefit and to protect your skin while it's extra sensitive.
