Good to know.
How is a hydrogel mask different from a sheet mask?
Hydrogel holds far more moisture and vacuum-fits to the skin, so active ingredients are delivered deeper. KOID soaks the sheet with essence — your skin takes what it can, and nothing is left behind.
How long should I leave it on?
Whatever your day allows: 3 minutes to prep, 30 to soothe, 60 to nourish. It won't dry out, so longer wear means deeper care.
Is it suitable for sensitive skin?
The formula scored 0.00 on a clinical irritation test (lowest-grade, non-irritating). It does contain natural fragrance allergens — please check the full ingredient list if you have known sensitivities.
What does the cooling come from?
The cooling is physical — from the hydrogel itself and Irish moss, not from menthol. A thermal-imaging test recorded a notable drop in skin temperature.
How is it shipped, and how long does it take?
Orders ship from Korea. Delivery time and cost vary by destination — see checkout for the rate to your country. Free shipping over $35 within Korea.
Can I cancel or return my order?
