The Claim
There is a belief that hyaluronic acid can substitute collagen in the skin, thus maintaining its youthful structure and firmness.
Origin
This myth is propagated through skincare product marketing that equates the moisturizing benefits of hyaluronic acid with the structural benefits of collagen.
What Science Says
Scientific evidence shows that hyaluronic acid and collagen serve different functions in the skin. Hyaluronic acid primarily hydrates and binds moisture, while collagen provides structural support. Studies confirm that hyaluronic acid does not replicate the structural properties of collagen.
Verdict
False
