Ingredient analysis and how the ad lines read
Read on 2026-09-23
What is this product?
A hydrating sheet mask built around eight hyaluronic acid forms with printed ppb concentrations and panthenol, aimed at moisture replenishment with soothing support.
What makes it different?
The eight hyaluronic acid variants appear consecutively from position 9 to 16 with printed ppb values, led by sodium hyaluronate at 40,000 ppb, which is unusual transparency for a sheet mask. Panthenol sits eighth in the list. The base is a light water, glycerin and glycol humectant system with allantoin and trehalose. Fragrance is present at the end of the list.
