FAQ

Q1: Is this serum suitable for sensitive skin?
A1: The formula includes Allantoin and Centella Asiatica extract to keep skin feeling comfortable. If your skin is sensitive, patch test on a small area first and start with once a day.

Q2: The product contains oil. Will it feel heavy on oily skin in hot weather?
A2: The micro-oil droplets are very fine and absorb quickly, so the finish stays light and fresh rather than oily.

Q3: Why does my skin look glowy after use?
A3: The multi-layer HA hydrates and the micro-oil droplets reflect light, giving skin a soft, healthy-looking glow.
