numbuzin No.1 Serum — Pantothenic B5 Oil-Control Serum for Oily, Acne-Prone Skin (1.69 fl oz) Lightweight, Fast-Absorbing

numbuzin No.1 Serum is a lightweight pantothenic acid–forward daily serum that soothes skin, controls excess oil, and helps prevent breakouts.

This fast-absorbing serum blends pantothenic acid (B5) microparticles with niacinamide, hyaluronic acid, panthenol, and beta-sitosterol to target oily, acne-prone skin without drying. Formulated to sink in quickly and hydrate deeply, it aims to reduce pore-clogging sebum while calming inflammation, making it suitable for sensitive and combination complexions that need oil regulation and moisture balance.

How does numbuzin No.1 Serum reduce breakouts while hydrating?

The serum uses pantothenic acid microparticles to help regulate sebum production and reduce the likelihood of clogged pores. Complementary ingredients like niacinamide and hyaluronic acid deliver hydration and barrier support so skin isn’t stripped of moisture during oil control.

• Pantothenic acid targets excess oil and pore-clogging sebum.
• Niacinamide supports barrier repair and evens skin tone.
• Hyaluronic acid provides multi-layer hydration without heaviness.
• Panthenol soothes inflamed or irritated areas.

Will it feel heavy or leave a residue on oily skin?

numbuzin No.1 Serum is formulated to absorb rapidly for a lightweight finish; it is designed to sink in within seconds rather than sit on the surface. The texture aims to deliver moisture and actives without a greasy film, making it comfortable under moisturizers or makeup.

• Fast-absorbing texture that sinks in quickly.
• Non-greasy finish appropriate for morning routines.
• Compatible with layered skincare and sunscreen.

How quickly can you expect visible improvement?

Clinical testing reported measurable reductions in breakouts and oil production in roughly four weeks when used consistently. Individual results vary, but many users notice reduced shine and fewer new blemishes within several weeks of daily application.

• Clinically tested to reduce breakouts and excess oil in 4 weeks.
• Best results with consistent morning and/or evening use.
• Works well alongside spot treatments and gentle cleansers.

How should it be used in my daily routine?

Apply the serum to clean, dry skin after cleansing and toning, then follow with moisturizer and sunscreen for daytime use. A small pump or dropper amount is enough; gently press into areas prone to oiliness or breakouts.

• Use once or twice daily on cleansed skin.
• Follow with a non-comedogenic moisturizer.
• Always apply SPF during the day after the serum.

Who is this for: numbuzin No.1 Serum is suited to people with oily, combination, or acne-prone skin looking to manage excess sebum and reduce breakouts without overdrying. It is also appropriate for those with sensitive skin who need a soothing, hydrating formula that supports the skin barrier while controlling shine. If you want a lightweight, B5-focused treatment to sit comfortably under other skincare and makeup, this serum is formulated to fit into that role.
