Description
Get ready to glow with Numbuzin No.4 Ceramide AHA Glazed Skin Prep Serum 30ml, your gentle yet effective exfoliation step that refines texture while keeping your skin barrier healthy.
This serum combines 3% AHA (glycolic acid) and 3% PHA (gluconolactone) to softly dissolve dead skin cells and smooth rough patches. These acids work in harmony: AHA helps with surface exfoliation and brightening, while PHA tends to be gentler, helping those with sensitive or flaky skin avoid irritation.
To ensure exfoliation never compromises skin health, this formula features a blend of five types of ceramides, plus panthenol and niacinamide. These ingredients lock in moisture, strengthen the skin barrier, reduce transepidermal water loss, calm redness, and support skin repair.
The texture is lightweight and milky — it glides on smoothly, absorbs well, and doesn’t leave sticky or heavy residue. When used correctly, it reveals a radiant, glazed (“glazed‑skin”) finish: skin looks more even, smoother, healthier, with a subtle glow.
This serum also doubles as a prep step: applying before your moisturizer or makeup helps the rest of your skincare absorb better and lay more evenly.

💡 How to Use
After cleansing (and optionally toning), apply a moderate amount of serum to clean, dry skin.
Gently pat in until fully absorbed.
Use in PM or during the day, but always follow with sunscreen afterward, since acids increase sun sensitivity.
If new to acids, start with every other night, then increase frequency as tolerated.
⚠️ Skin Types & Precautions
Works well for all skin types, especially sensitive, textured, dry, or flaky skin. Avoid using with other strong exfoliants on the same night. Discontinue if persistent irritation occurs.
