I liked this product a lot for the that it has black snail collagen. I think it definitely helps with the cream's firming and tightening effects and that was exactly what I was looking for from using it. Although I didn't enjoy the slimy-like texture of it as much-- not from the application perspective, but the container gets a bit messy when using the product. Nonetheless, it's less of a concern considering how firm and dewy this cream gets your skin!
