By now you've probably surmised that collagen supplements aren't a necessary — or even recommended — part of your skin care regimen. Fortunately, you've got a number of alternatives.

"To increase the skin's collagen, it seems that it is most beneficial to aim to stop collagen degradation and work to increase the body's own production of collagen rather than attempting to consume animal-based collagen," says Black. "The best way to stop collagen degradation is to wear a daily sunblock with an SPF of 30 or higher to protect it from the sun's harmful radiation."

She adds that a healthy diet also plays a pivotal role in our overall health and, therefore, the appearance of our skin. Specifically, a diet rich in antioxidants and low in processed foods may help the skin to repair the oxidative damage from the environment such as the sun's radiation.

For a more aggressive approach, Goldburt also recommends laser treatments, which actually have been scientifically proven to stimulate collagen production in the skin. Microneedle and PRP treatments, when performed correctly, have been proven effective, as well.

In addition to the above, consistent application of topical vitamin A (retinoids) can repair and prevent signs of aging. Not only is there a mountain of research backing up topical usage of vitamin A, you'll be hard-pressed to find a dermatologist who doesn't regularly apply it themselves.
