FAQ
Q1: Does hyaluronic acid need moisturizer on top?
A: In dry or air-conditioned air, yes — HA draws moisture from the skin when humidity is low, and an occlusive layer stops the loss.
Q2: What if I skip it?
A: In dry air, skipping the sealer can leave skin tighter than before — the classic HA rebound.
Q3: What should I use on top?
A: Any moisturizer with an occlusive ingredient, or a drop of facial oil, seals the HA layer.
