Hyaluronic acid is a glycosaminoglycan naturally present in skin. Applied topically it forms a breathable hydration film that draws water into the upper layers — instantly plumping the look of fine dehydration lines.
Coyglow pairs high- and low-molecular-weight HA chains: the larger ones surface-hydrate, the smaller ones penetrate deeper for a cushioned, layered effect.
How to use: Apply to damp skin, then seal with a moisturizer — HA needs water to hold and a barrier to keep it.
Cautions: In very dry climates, always layer over a mist; undiluted HA can pull moisture outward.
