Hydro Cera-nol Real Deep Mask (4 masks)

The Hydro Cera-nol Real Deep Mask is Biodance's second hydrogel mask, built around Hydro Cera-nol, the brand's own ingredient name, and glacial water. Biodance says each mask is about 1.19 oz of ampoule set into a gel sheet. The ingredient list includes niacinamide, panthenol, several forms of hyaluronic acid and five ceramides. This Amazon listing is the four-mask pack, sold by Biodance. Biodance gives the same directions as for its collagen mask: three to four hours after toner, until it turns clear, or overnight.
