I've heard that hyaluronic acid applied topically causes bad "softening" of the skin, which is not recommended. Other sites state that it improves the look of wrinkles. Is it safe or not? And if it is, does it work?
Is Hyaluronic Acid Safe for Topical Use, and is It Effective?

Topical hyaluronic acid is safe and common in skin products
Hyaluronic acid is a moisturizer used in many cosmetic preparations. In available forms, the HA molecule is too large to penetrate the skin, so the effects can only be temporary.
HA helps hold moisture (water) so that the epidermal cells fell and look softer. This is not a bad thing and you should not worry that the presence of it in your cosmetic creams would be problematic.
As physicians use hyaluronic acid for cosmetic injections, orthopedic surgery and eye surgery, but this is a different formulation and far too expensive to spread on the skin topically.
Our body contains its own hyaluronic acid and this helps keep our skin soft and our joints moving smoothly.
