If you’ve ever read anything about how the skin ages, you’re probably familiar with collagen. It’s the protein that’s responsible for keeping our skin youthful looking — and as we age, our natural supply of it declines. (Hence why so many people seek out collagen injections as line fillers.)

The best way to boost collagen, in my opinion, is from the inside. Collagen creams are available, but the collagen molecules are too big to actually penetrate the skin, so they’re essentially just really good moisturizers. While injections may be preferred by some people, you should also know that they’re definitely not the only way to internally boost the collagen in your skin. Thankfully, there are several foods that help your body maintain or create more collagen naturally!

Here are five of my favorites. Incorporate them into your diet for some skin-focused TLC – not to mention an overall health boost.
