Why leave it on for three hours?
The longer you wear it, the deeper it penetrates.
Why it's worth buying
Hydrating, firming, and overnight wear—all in one

Sheet masks start drying out after 15 minutes, and you risk reverse absorption if you leave them on longer. This hydrogel mask locks in 34g of essence, staying moist for 3–4 hours. Perfect for lazy days—just put it on before bed and remove it in the morning for deep, overnight absorption.
With regular masks, you never know when to take them off. Remove too early and you waste product; too late and your skin dries out. This starts as a white hydrogel and turns transparent as your skin absorbs the essence. Transparency is your signal—it's easy even for beginners.


Dealing with enlarged pores or sagging skin? Our 243Da ultra-low molecular collagen penetrates deeply. Combined with oligo-hyaluronic acid for moisture and galactomyces ferment filtrate for elasticity, it deeply hydrates while helping to tighten pores, leaving your cheeks firm and plump.

34g of essence to wear overnight; remove once it turns transparent. Hydration and firming in one step.
The honest truth
Korea's Olive Young No.1 mask; frequently sold out.
The smaller the molecular weight, the higher the absorption rate. Officially verified 243Da ultra-low molecular collagen.
Tested to be fragrance-free with a two-piece design that fits well; comfortable for overnight use.

Why do I need to wear it for 3–4 hours?
The hydrogel texture locks in 34g of essence and releases it slowly. Unlike sheet masks, it doesn't dry out quickly, allowing the essence to penetrate deeply. You can wear it for 1 hour if you're in a rush, but the longer you wear it, the better the results.
Will it cause reverse absorption if I wear it overnight?
The hydrogel's moisture-locking design is different from sheet masks. Official usage includes overnight wear. Once the skin absorbs the essence, the mask turns transparent; just remove it when you wake up.
Is this the same as the one sold at Watsons or Sasa?
Yes, it is the same original Korean product. We source via parallel import, which is why our price is more competitive.
