Direct answer: BIODANCE Bio-Collagen Real Deep Mask Sheet 4P is a four-piece hydrogel mask format. The brand describes low-molecular collagen, oligo hyaluronic acid, and galactomyces as key formula points.
What to compare
Compare format, pack size, and routine order. This is a hydrogel mask rather than a conventional essence sheet. The brand directions place it after cleansing and toner, with removal when the gel becomes transparent.
