Hyaluronic Acid
Hyaluronic acid is a humectant — it doesn't add oil or lipids, it draws water into the skin's surface. That only works if there's water nearby to draw from, which is why it's meant to go on damp skin and get sealed in with a moisturizer, not applied to bone-dry skin in a dry room.
How it works
A high-molecular-weight glycosaminoglycan that functions as a structural humectant, cross-linking water molecules to retain up to one thousand times its weight in water. It establishes a non-occlusive, viscoelastic film over the stratum corneum to dramatically increase hydration metrics.
In practice, applying it to dry skin in a dry room can backfire, pulling moisture from the skin itself rather than the air — damp skin first is what makes it work.
How to introduce it
Wait about 2 minutes before the next step. Judging Hyaluronic Acid before week 4 means judging it before it's had time to actually work — most of what reads as "this isn't doing anything" in the first couple of weeks is just too early to tell.
- Apply to damp skin, then seal with moisturizer — on dry skin in low humidity it can pull water from the skin instead of the air.
Who should be careful
Hyaluronic Acid's safety rating is the lowest tier tracked here — well tolerated by most skin types, including sensitive skin, without a slow introduction.

Common in these product forms
Among the products Skinzy tracks in India that contain Hyaluronic Acid, it most often shows up as a moisturizer or a serum.
Questions people ask
Pulls water into the skin's surface for an instant plumping effect — apply to damp skin, then seal with moisturizer.
Most people see a fair result around 4 weeks of consistent use — judging earlier usually means judging too soon.
Either — Hyaluronic Acid works in both a morning and an evening routine.
