Never did I think $25 could be so well spent. I have heard about the impressive benefits of snail mucin but have been too grossed out to try it, until my friend who is a dermatologist PA learned about it in one of her conferences. So I decided $25 was a low cost of entry and I’m so glad I bought this COSRX from Ulta set to try- my skin was so smooth this morning after using just the booster and essence. I have VERY reactive, rosacea afflicted skin and this did NOT irritate it (again, only used a couple products). koreanskincare snailmucin skincare rosacea cosrx ultabeauty LTKselfcare LTKFindsUnder50 LTKBeauty
