numbuzin No.4 Ceramide AHA Glazed Skin Prep Serum 1.3ml x 10

A lightweight prep serum that combines exfoliating acids and skin-barrier ceramides to reveal smoother, more radiant skin before the rest of your routine.

Texture: Fluid, fast-absorbing serum

Finish: Dewy, glazed-looking skin

Hydration: Triple hyaluronic acid complex plus panthenol and beta-glucan deliver multi-level moisture

Target: Dull, rough, or dry skin needing gentle resurfacing and barrier support

Proof: 3% AHA (glycolic acid) and 3% PHA (gluconolactone) exfoliate without harsh irritation; five ceramide types reinforce the moisture barrier

Best for: All skin types, especially dry or sensitive skin that needs both exfoliation and hydration

Key Ingredients

• Glycolic Acid (AHA, 3%) — gently resurfaces dead skin cells to help smooth texture and support a brighter complexion
• Gluconolactone (PHA, 3%) — provides mild exfoliation with added moisture-binding properties, well-suited for sensitive skin
• Ceramide Complex (NP, NS, AP, AS, EOP) — five ceramide types work together to reinforce the skin barrier and help lock in hydration
• Niacinamide — helps visibly even skin tone and supports a healthy-looking, more luminous complexion
• Panthenol (2%) — draws moisture into the skin and helps soothe dryness and irritation

How to Use

1. After cleansing and toning, dispense one 1.3 ml capsule onto your fingertips.

2. Apply evenly across the face and gently pat until fully absorbed.

3. Follow with your usual serums and moisturizer.

4. If using in the morning, always finish with a broad-spectrum sunscreen — the active acids can increase sun sensitivity.
