What are the key ingredients and what do they do?

numbuzin No.1 centers on pantothenic acid (vitamin B5) microparticles to help regulate sebum and reduce pore congestion. Niacinamide helps even skin tone and strengthen the skin barrier, while hyaluronic acid delivers hydration. Panthenol and beta-sitosterol provide soothing support to calm irritation and promote comfort.

• Pantothenic acid microparticles: oil regulation and pore support
• Niacinamide: barrier support and tone balancing
• Hyaluronic acid: lightweight hydration for plumper skin
• Panthenol and beta-sitosterol: reduce redness and soothe

How should I use this serum in my skincare routine?

Apply a few drops to clean, slightly damp skin once or twice daily, then follow with a moisturizer and SPF in the morning. Because the serum is lightweight and non-comedogenic, it layers well under heavier creams or oils. Start with nightly use if you have sensitive skin, then increase frequency as tolerated.

• Use on cleansed face and neck, on damp skin for best absorption
• Follow with moisturizer; always apply sunscreen daytime
• Patch-test new products and introduce gradually if sensitive

Is this serum appropriate for sensitive or acne-prone skin?

The formulation is described as non-comedogenic and includes soothing agents to reduce irritation, so it’s designed with acne-prone and reactive skin in mind. Pantothenic acid provides oil-regulating benefits without harsh exfoliation. If you use prescription acne treatments, consult your dermatologist before combining active products.

• Non-comedogenic formula reduces pore-clogging risk
• Soothe-focused ingredients minimize irritation
• Compatible with many acne-prone skin routines—check interactions
