See the scientific wording

Oral supplementation with 200 mg of hyaluronic acid daily improves skin hydration and reduces wrinkle depth in humans.

Why this might work

When hyaluronic acid is swallowed, it passes through the gut, where bacteria break it into smaller pieces that enter the bloodstream. These pieces travel to the skin and are taken up by cells that make the skin's structural framework. These cells then produce more of their own hyaluronic acid and other proteins that hold water and keep skin firm. The increased water content plumps the skin, and the strengthened structure prevents wrinkles from forming.

What the research says

2 studies

  1. Study: Oral Hyaluronic Acid Supplement: Efficacy in Skin Hydration, Elasticity, and Wrinkle Depth Reduction.

    Taking 200 mg of hyaluronic acid every day helped people's skin hold more water and reduced wrinkles, according to a review of seven good-quality studies. So yes, it seems to work as claimed.

  2. Study: Ingestion of an Oral Hyaluronan Solution Improves Skin Hydration, Wrinkle Reduction, Elasticity, and Skin Roughness: Results of a Clinical Study

    People who took a daily drink containing hyaluronic acid (along with a few other vitamins) saw their skin get more hydrated and wrinkles become less deep after 40 days. This suggests that taking hyaluronic acid by mouth may help skin, even if the exact product wasn’t pure hyaluronic acid.
