Numbuzin No.4 Ceramide AHA Glazed Skin Prep Serum is a Korean face serum from the numbered Numbuzin line. It comes in a clean white dropper bottle with a silver collar, a large number 4, and a label that names glycolic acid and ceramide as its featured ingredients.
The brand guide for this serum suggests using it morning and night, as a prep step before the rest of your routine, and for people with dry and sensitive skin. After cleansing, place a few drops into your palm or onto your face and pat it in gently. Then layer on your favorite serums or moisturizer. Since it contains an AHA, wear sunscreen during the day.
Many skincare fans like collecting the Numbuzin numbers and mixing them into a routine that fits their needs. The No.4 serum is the prep option in that lineup and is easy to slip into a simple everyday routine. Patch test first if you are trying acids for the first time.
