Lala told E!, "Oh my gosh, the hype is real, and I cosign on it. I will go to the desert where it's so dry, and I'll put that snail mucin on and mix it with whatever moisturizer I'm using. And I kid you not, I wake up and my skin is like butter."

Snail Mucin 96% Power Essence

Made with 96.3% snail secretion filtrate, this lightweight essence reduces dullness and soothes dehydrated skin. It absorbs quickly into the skin, providing hydration without feeling heavy.

"I’ve been using this for a year, and it’s one of the few products that truly supports my skin barrier. I use tretinoin regularly, and this essence has been a game-changer for minimizing irritation and dryness. It creates a light, protective layer that helps my skin stay calm and hydrated overnight, so I don’t wake up flaky or tight," one shopper wrote.

Another Amazon customer said: "After consistent use, my skin feels softer, smoother, and more plump. It also layers well under moisturizer or makeup, which is a big plus. The snail mucin does a great job at repairing and soothing damaged or dry skin."

"I love this snail mucin serum! It really helps protect my skin and keeps it feeling soft and hydrated all day. I’ve noticed better skin tone and a healthy glow since using it regularly," a reviewer shared.
