numbuzin No.1 Serum — Pantothenic B5 Oil-Control Serum (1.69 fl oz) with Niacinamide & Hyaluronic Acid for Oily, Acne-Prone Skin

numbuzin No.1 Serum is a lightweight pantothenic-acid (B5) serum formulated to soothe, hydrate, and help control excess oil for clearer, calmer skin.

This fast-absorbing 1.69 fl. oz. serum blends pantothenic acid microparticles with niacinamide, hyaluronic acid and panthenol to target oiliness, pore congestion and surface inflammation without heavy residues. Designed for daily use, it layers easily under moisturizers and makeup and aims to balance skin that is oily, acne-prone, or combination while also providing hydration to avoid dehydration from oil-control routines.

How does this serum help reduce breakouts and excess oil?

The formula focuses on regulating sebum production and keeping pores clear so that fewer comedones and inflammatory blemishes form. Pantothenic acid works alongside niacinamide to support skin barrier function and reduce the factors that contribute to clogged pores.

• Pantothenic acid microparticles to support balanced oil production.
• Niacinamide to help minimize pore appearance and strengthen barrier.
• Lightweight texture that absorbs quickly—no greasy finish.

What key ingredients are in numbuzin No.1 Serum and why they matter?

This serum combines several active ingredients chosen for hydration, soothing and oil regulation rather than aggressive drying. Each ingredient has a role: hydrating molecules retain moisture while soothing agents calm redness, and oil-regulating actives help prevent pore blockage.

• Pantothenic acid (B5) microparticles for oil regulation.
• Niacinamide to support barrier repair and even skin texture.
• Hyaluronic acid for multi-depth hydration.
• Panthenol and beta-sitosterol to soothe and reduce surface irritation.

How should I use the serum in my daily routine?

Apply after cleansing and any water-based treatments, while skin is slightly damp to lock in moisture. Use a pea-sized amount across the face once or twice daily depending on tolerance, then follow with moisturizer and sunscreen in the morning.

• Cleanse and pat skin slightly damp.
• Dispense a small amount and gently press into face and neck.
• Layer moisturizer and SPF after absorption for daytime protection.

What results can I expect and when might I see them?

Users often notice a lighter, non-greasy finish and improved hydration within days; changes in oil control and fewer breakouts typically appear over several weeks as skin adjusts. A published clinical evaluation reported measurable reductions in breakouts and oiliness over a four-week period in test subjects, but individual responses vary.

• Quick absorption—minimal tack within seconds.
• Hydration that supports barrier balance to avoid over-drying.
• Gradual reduction in breakouts with consistent use.

Who is this for: numbuzin No.1 Serum is formulated for people with oily, acne-prone, combination or dehydrated skin who want a lightweight daily serum that targets excess oil and pore congestion while maintaining hydration. It is suitable for sensitive skin types seeking gentler, non-comedogenic support; those using active acne treatments should introduce it gradually and consult a skin professional if combining with prescription products.
