It's a good hydration boost! It didn't cause me any skin issues, it's easily absorved and it's not sticky.

Great for a compromised skin barrier. Feels super hydrating and occlusive -- similar to a snail mucin texture. Leaves a bit of a sticky/tacky finish, which doubles as a primer under makeup. Also makes the skin super glowy. WRP (just wish it was fragrance-free).
It is super hydrating and i use it mostly on those days i dont want to do too much.. I cleanse, use this and sunscreen👏🏾
