Ingredient analysis and how the ad lines read
Read on 2026-09-22
What is this product?
A brightening functional sheet mask whose formula puts arbutin high in the list, at item four, alongside many plant extracts, but the printed concentrations and any efficacy testing are not disclosed.
What makes it different?
Arbutin sits fourth among 31 ingredients, which is a genuinely high placement for a spot-care sheet mask. The formula also carries a long tail of plant extracts, including 다마스크장미꽃오일, 신선초추출물 and 붉나무충영추출물. It is registered as a 미백 functional cosmetic, and the brand notes its 에탄올 is a plant-fermented ingredient. Essential oils and 에탄올 are both present, so very reactive skin should weigh that.
