numbuzin Ceramide AHA PHA Glazed Skin Prep Serum — Glycolic Exfoliant with Ceramides & Panthenol, 1.01 fl oz

This serum pairs chemical exfoliants with barrier-supporting ingredients so you can refine skin texture without over-drying. The formula uses glycolic acid for surface renewal and a mild polyhydroxy acid (PHA) to help exfoliate more gently, while ceramides and panthenol maintain moisture and help soothe skin. Fast-absorbing and non-sticky, it's designed as the first step in your routine or a daily prep layer before moisturizing and makeup.

How does this serum improve skin texture?

Glycolic acid helps loosen dead skin cells on the surface, while PHA supports gentle exfoliation with lower irritation risk. Together they help reduce rough patches and promote a smoother-looking complexion that reflects light more evenly.

• Contains glycolic acid for effective surface exfoliation.
• PHA provides gentler, hydration-friendly exfoliation.
• Visibly refines pores and evens skin texture over time.

Will it strip my skin or weaken my moisture barrier?

This formula is balanced to exfoliate without excessive dryness. Ceramides and panthenol are included to reinforce the skin’s lipid layer and retain hydration while exfoliants renew the surface.

• Ceramides help replenish essential skin lipids for barrier support.
• Panthenol adds soothing hydration to reduce tightness.
• Lightweight base minimizes heavy or tacky residue after application.

How do I add numbuzin No.4 to my daily routine?

Apply a few drops to clean, dry skin as the first step after cleansing; follow with moisturizer and SPF in the morning. It absorbs quickly, so you can layer serums or sunscreen without pilling.

• Use once daily, morning or evening, depending on tolerance.
• Follow with moisturizer to lock in hydration and sunscreen if used in the daytime.
• Introduce gradually if your skin is reactive—every other day, then increase.

Is this suitable for sensitive or dry skin types?

numbuzin No.4 is formulated to be gentle enough for many skin types, including dry and sensitive skin, by combining mild exfoliants with barrier-supporting ingredients. However, patch-testing is recommended for those with extreme sensitivity or active irritation.

• PHA provides a lower-irritation alternative to stronger AHAs alone.
• Ceramides and panthenol soothe and help prevent moisture loss.
• Observe skin response and reduce frequency if stinging occurs.

Who is this for: This serum is aimed at people wanting a smoother, more even complexion and a polished base for makeup—those with rough texture, visible pores, or flaky areas who prefer a gentle, hydration-conscious approach to chemical exfoliation. It’s also suitable for anyone seeking a fast-absorbing prep step that supports the skin barrier while refining surface texture.
