"Experience a serum toner that manages deep moisturization up to 15 layers in the skin. It consists of 3% grape seed oil + 97% serum water to balance oil and water content and prevent moisture from evaporating in dry environments. It is absorbed up to the 15th layer of the stratum corneum and sufficiently fills the inside and outside of the skin. The oil-water balance is perfect, which has the effect of strengthening the skin barrier."
