    This serum has quickly become one of my favourites of all time! I really recommend this for oily/dehydrated skin because it feels so lightweight but so hydrating. A few drops on the face gives instantly plump skin. You get that same sort of hydrated glow you’d get from doing a sheet mask. Works so nicely under makeup too. I’ve been using it for a few weeks now and have barely made a dent even though I use it day and night. A little goes a long way!

    This is by far my favorite nighttime serum. It was the first Korean serum I purchased, along with the Numbuzin No.3 Skin Softening Serum, and it has been a game changer. I started using it in February, and within three months, I began receiving compliments about my skin—everyone assumed it was genetics, but it was actually these serums.

    Initially, I used it both day and night with the Numbuzin No.3 Skin Softening Serum, but recently, I switched to using it only at night as part of my skincare routine. It leaves my skin feeling super hydrated, dewy, and healthy, almost as if I’ve used a sheet mask. The product lasts a long time—I’ve been using it since February, and it’s still going strong. I will definitely repurchase it. It’s one of the best skincare investments you can make. My skin has never been this happy and hydrated.
