Elizavecca Gold CF-Nest Collagen Jella Pack Mask is an anti-aging peel-off mask. This mask is formulated with Swiftlet Nest Extract to boost skin elasticity, brighten complexion, fight wrinkles & firm skin. It has a thick gel-like texture. Apply to clean skin, let completely dry 20-30 minutes, then gently peel off from the edge. It has a nice cooling effect on the skin and I had no irritation. I left it on for 40 minutes and I used a fan to help it dry, it was still very hard to peel off, so I ended up washing it off. It left my skin feeling soft and hydrated.
