numbuzin No.4 Serum | Ceramide AHA Glazed Skin Prep Serum | Exfoliating, Skin Barrier Repair, Face peel, Korean Glass Face |

[Barrier-Safe Exfoliating & Skin Prep Serum] A milky exfoliating serum that gently melts away dead skin cells—without the redness or irritation common in traditional exfoliants. Specifically designed for dry, flaky, and sensitive skin, this silky formula works by softly pressing down and dissolving uneven texture, revealing a smooth, glazed-skin glow.

[Key Ingredients] Formulated with 3% AHA (Glycolic Acid), 3% PHA, and a blend of 5 ceramides, this gentle exfoliating formula offers mild yet effective resurfacing without damaging the skin barrier. The combination of AHA and PHA provides chemical exfoliation that smooths and refines the skin’s texture, leaving it soft and silky—without irritation. Meanwhile, 5 types of ceramides deeply hydrate and strengthen the skin barrier to prevent damage, while panthenol adds support for skin recovery and protection.

[Clinically Tested] Clinically proven to improve surface and deeper exfoliation, refine skin texture, repair the damaged skin barrier, and enhance makeup longevity.

[Recommended For] All skin types, especially those with dry, flaky, sensitive, textured skin. Perfect for those looking to achieve smooth, even skin texture and a radiant, glow.

[numbuzin 4, How to Use] Use one full dropper on clean skin before other skincare. Ideal before makeup or as a part of your skincare routine to improve absorption and boost glow.
