In this mask, the key anti-wrinkle ingredient is SYN®-AKE, a synthetic snake venom peptide. It is designed to mimic the action of waglerin-1, a peptide originally identified in the venom of the Temple Viper, but the product is a topical cosmetic sheet mask rather than an injectable or medical treatment.
SYN®-AKE works on the upper layers of the skin and is used in K-beauty for the appearance of expression lines. The idea is to help reduce visible tension around areas where fine lines often form, such as the forehead, eye contour and mouth area. With regular use, these lines may look softer, but the result is cosmetic and temporary.
It should not “freeze” your facial expression. Unlike injectable procedures, a sheet mask does not immobilise facial muscles or create a long-lasting structural change. The more immediate effect you are likely to notice from this type of mask is hydration: the fabric keeps the serum in contact with the skin for 15–20 minutes, helping the face look plumper, smoother and more refreshed after use.
