Taking hyaluronic acid pills might trick your skin cells into making more of their own hyaluronic acid and collagen by sending signals from your gut, which could help your skin look healthier.

If you take hyaluronic acid pills, it might help your skin stay healthier and less red by feeding good gut bacteria that send calming signals to your skin.

Taking hyaluronan by mouth might help your skin make more of its own hyaluronan and boost skin cell growth, according to lab and animal studies.

When mice eat hyaluronan, it’s probably not the whole molecule that helps their skin and joints—it’s the smaller pieces it breaks down into that do the work.
