1 interaction related to hyaluronic acid
Hyaluronic acid and collagen are the two dominant structural components of the skin's extracellular matrix — collagen provides tensile strength while hyaluronic acid binds water and provides cushioning. Each, taken orally, has human trial support for modest improvements in skin hydration and elasticity, and they act on the same tissue from complementary angles. A true additive benefit over either ingredient alone has not been proven in humans, so the pairing is best treated as plausible and low-risk rather than a confirmed synergy.
