This two-step face mask pairs the good-skin benefits of hydrating hyaluronic acid with collagen-stimulating plant stem cells (from callus extract) to visibly improve skin’s density and texture. Added marine collagen boosts skin’s firmness and hydration levels even more while ginseng extract - rich in saponins and polyphenols - is key for pepping up a dull, tired complexion. To get the most benefits, apply the hyaluronic acid essence all-over cleansed skin before fitting the sheet mask overtop. After twenty minutes, remove the mask and massage in any leftover essence.
