Moderate evidenceHyaluronic Acid for Sun Damage (Photoaging)
A pure hydrator that holds water in your skin. Makes skin look plumper and smoother almost immediately.
Why it works for Sun Damage (Photoaging)
A water-binding molecule that the skin makes naturally, but UV exposure breaks it down and depletes it. Applied on top, it hydrates the surface and gives a short-term improvement in roughness and fine lines. It does not repair sun damage, but it plumps and smooths skin right away and supports the barrier, which is often weakened in sun-damaged skin.
How Hyaluronic Acid works
Polysaccharide humectant that binds up to 1000x its weight in water within the stratum corneum.
