Numbuzin No.3 Blue Bio-Retinol Pore Refining Serum

Numbuzin No.3 Blue Bio-Retinol Pore Refining Serum pairs an encapsulated “blue bio-retinol” with 10% niacinamide and 0.2% salicylic acid (BHA) to target enlarged-looking pores and uneven texture. The encapsulation is designed to release retinol gradually, making the formula more approachable for retinol beginners and sensitive skin than many traditional retinol serums.

Key Benefits

• Encapsulated Blue Bio-Retinol technology formulated to be gentler on skin than uncoated retinol
• 10% Niacinamide to support smoother-looking texture and tone
• 0.2% Salicylic Acid (BHA) to help clear and refine the look of pores
• Centella Asiatica Extract and Panthenol to help support the skin barrier while exfoliating actives work
• Alcohol-free and fragrance/essential-oil-free
• Positioned by the brand as suitable for all skin types, including retinol beginners and sensitive skin

When to Use

Morning and night per the brand's instructions, as a treatment step after cleansing and toner and before moisturizer. Targets enlarged pores, rough texture, and early fine lines. Because this contains retinol, those new to retinol may prefer to start with nightly use only and build up frequency gradually. Daily sunscreen is essential when using this product.

How to Use

Apply 2–3 drops (or a small amount) to clean, toned skin. Spread over the face and neck, pat until absorbed, then seal with moisturizer. Apply broad-spectrum sunscreen each morning.

Key Ingredients

• Retinol (encapsulated “Blue Bio-Retinol”): cell-communicating ingredient that supports the look of smoother texture and firmness, with a gradual-release design intended to reduce irritation.
• Niacinamide (10%): supports tone evenness and barrier function.
• Salicylic Acid (0.2%, BHA): helps clear and refine the look of pores.
• Centella Asiatica Extract: soothing botanical extract.
• Panthenol (Provitamin B5): hydrating, skin-soothing ingredient.
• Copper Tripeptide-1: cell-communicating ingredient that supports the look of firmness.

Precautions

Patch test before first use. Because this product contains retinol, those new to retinol should introduce it gradually and avoid layering with other strong exfoliants or retinoids in the same routine. Use daily sunscreen, avoid direct eye contact, and discontinue use if persistent irritation occurs.
