I had heard about snail slime for the longest time, but only tried it for the first time last month. The hype is real! CosRX' snail mucin feels so lovely and nourishing when applied, and it leaves the nicest finish on the skin. If my skin was clear and didn't need the extra boost of moisturizer, I would leave it like that because the finish this leaves is very glass-skin-like but in a fresh, not-sweaty kind of way. As far as repairing the damage to my skin, I do find this very soothing and plumping upon immediate application but I can't say that it's singlehandedly fixed my overly sensitized skin. That being said, I think this has become an essential step in my routine.
