A short sheet-mask step or a longer hydrogel mask?
ANUA Heartleaf 77 Soothing Mask is an essence-soaked sheet mask for a short skincare break. Heartleaf 70 Soothing Collagen Mask uses a two-piece hydrogel sheet and stays on much longer, gradually becoming transparent.
Both belong to the Heartleaf collection.
