NUMBUZIN No.4 Ceramide AHA Glazed Skin Prep Serum is a Korean dual-action skin prep serum. It contains 3% glycolic acid (AHA) and 3% gluconolactone (PHA) for gentle exfoliation, smoothing texture, reducing flakiness, and brightening dull skin. Infused with 5 types of ceramides, panthenol, and niacinamide, it repairs and strengthens the skin barrier, deeply hydrates, and soothes irritation. The milky, fast-absorbing formula is alcohol-free, fragrance-free, and suitable for all skin types, especially dry, flaky, and sensitive skin. It preps skin for better absorption of subsequent products and creates a smooth, glazed, radiant complexion.
