About Numbuzin No.4 Ceramide AHA Glazed Skin Prep Serum
The Numbuzin No.4 Ceramide AHA Glazed Skin Prep Serum is a Korean milky serum that gently exfoliates dead skin and softens rough texture to give the skin a smooth, glowing "glazed skin" look. The word "prep" means it is designed to be used before the rest of your skincare — it clears away dead skin cells so your other products absorb better and your skin looks fresher. The vial set gives you 10 single-use tubes, each holding 1.3ml — hygienic, travel-friendly, and a smart way to try the product before buying the full 30ml bottle.
The formula works because AHA and PHA acids exfoliate while 5 types of Ceramides protect the skin barrier at the same time — so the skin gets smoother without getting irritated or dry. Niacinamide brightens, Panthenol heals, and triple Hyaluronic Acid keeps skin plump. Fragrance-free, alcohol-free, and safe for all skin types, including sensitive.
Key Benefits of Numbuzin No.4 Ceramide AHA Glazed Skin Prep Serum
- 3% Glycolic Acid (AHA) and 3% Gluconolactone (PHA) gently dissolve dead skin cells and smooth rough texture — giving skin a visible glazed, glass-like glow without peeling or irritation
- 5 types of Ceramides (NP, NS, AP, AS, EOP) rebuild and protect the skin barrier while the acids exfoliate — so skin gets smoother without becoming dry, red, or sensitive
- Niacinamide and Adenosine brighten skin tone and firm skin, while triple Hyaluronic Acid and Panthenol keep skin deeply hydrated and calm after every use
- Single-use 1.3ml vials keep the formula fresh and hygienic — perfect for travel, testing the product before committing to the full bottle, or consistent portion control
Skin Types and Concerns
- Dry and flaky skin: AHA + PHA dissolve dead skin buildup, while ceramides and Hyaluronic Acid hydrate deeply — skin feels smooth, not stripped
- Sensitive skin: PHA (Gluconolactone) is the mildest acid type and does not cause stinging — ceramides protect the barrier while exfoliation happens
- Dull and uneven skin tone: AHA exfoliation and Niacinamide together brighten skin and fade dark marks over time with regular use
- All skin types prepping for makeup: Smooths and refines texture so foundation and other products glide on more evenly and look better all day
Key Ingredients of Numbuzin No.4 Ceramide AHA Glazed Skin Prep Serum
- Glycolic Acid (AHA, 3.01%): The main exfoliating acid — dissolves the bonds holding dead skin cells together so they shed off cleanly. Smooths rough texture and helps fade dark spots over time.
- Gluconolactone (PHA, 3%): A gentle acid that exfoliates the skin surface without irritation. Best for sensitive skin — it also pulls in moisture while it exfoliates.
- 5-Type Ceramide Complex (NP, NS, AP, AS, EOP): Ceramides are the natural fats that hold the skin barrier together. These five types work together to repair and protect the skin while the acids exfoliate, so the barrier stays healthy.
- Niacinamide: Brightens dull skin, fades dark marks, and controls oil. Balances out the exfoliating acids in the formula.
- Panthenol (2%): Soothes and moisturizes the skin. Helps calm any mild sensitivity from the AHA and speeds up barrier recovery.
- Triple Hyaluronic Acid (Sodium Hyaluronate, Hydrolyzed Hyaluronic Acid, Sodium Hyaluronate Crosspolymer): Three forms of HA hydrate skin at different depths. Keeps skin plump and comfortable even after exfoliation.
- Beta-Glucan + Sphingomonas Ferment Extract: Beta-Glucan soothes and calms the skin. Sphingomonas Ferment is a fermented ingredient that helps hydrate and support the skin's natural barrier.
How to Use Numbuzin No.4 Ceramide AHA Glazed Skin Prep Serum
- Cleanse your face and pat it dry completely.
- Twist or snap open one vial.
- Apply the full vial content evenly across the face as the first step of your skincare routine.
- Gently pat until fully absorbed; do not rinse off.
- Follow with toner, serum, and moisturizer.
- Always apply sunscreen in the morning. AHA makes skin more sensitive to UV rays.
