numbuzin Blue Bio-Retinol No.3 Pore Refining Serum — 30ml Lightweight Retinol with 10% Niacinamide & BHA for Sensitive Skin

numbuzin No.3 Blue Bio-Retinol Pore Refining Serum is a gentle, beginner-friendly retinol formula that targets enlarged pores, uneven texture, and early signs of firmness loss with Blue Bio-Retinol, 10% niacinamide, BHA and peptides.

This lightweight 30 ml serum blends bio-based blue retinol with encapsulated pure retinol and supportive actives to refine pore appearance and smooth skin texture while minimizing irritation common to traditional retinol. Designed for everyday use and suitable for sensitive skin types, the formula balances exfoliation and barrier support so you can introduce retinol benefits without heavy dryness or stinging. It absorbs quickly and layers well under moisturizers and SPF.

How does this serum reduce the look of enlarged pores?

The serum combines Blue Bio-Retinol with 10% niacinamide and BHA to address multiple pore-related factors: surface congestion, loss of elasticity around pore walls, and uneven texture. These ingredients work together to visibly refine pore size and improve skin smoothness over time without aggressive irritation.

• Blue Bio-Retinol: bio-derived retinol that supports cell turnover with gentler tolerance.
• 10% niacinamide: strengthens barrier and helps regulate excess oil production.
• BHA (salicylic acid): penetrates pores to clear buildup and reduce congestion.
• Peptides: promote firmer skin surrounding pore openings for a tightened look.

Can beginners and sensitive skin users safely try this retinol?

Yes — the No.3 serum is formulated specifically for retinol beginners and those who react to ordinary retinoids. Encapsulation and a blue bio-retinol base lower the risk of irritation, while barrier-supporting niacinamide and peptides help maintain comfort during adaptation.

• Gentle encapsulated retinol system reduces direct exposure to pure retinol.
• Soothing niacinamide calms redness and supports skin repair.
• Use starts with a low frequency that can increase as tolerance builds.
• Recommended to apply with SPF during daytime to protect treated skin.

What results can I expect and how soon will I see them?

Improvements vary by individual, but many users notice smoother texture and reduced congestion within a few weeks, with more visible pore refinement and firmness over several months. The clinical testing behind the formula targeted ten pore-related concerns, focusing on size, depth, and overall appearance.

• Initial texture smoothing: often visible within 2–4 weeks.
• Reduced pore visibility and depth: typically more apparent after 6–12 weeks.
• Enhanced firmness and barrier support: gradual improvements with continued use.
• Best results when combined with sun protection and consistent application.

How should I add numbuzin No.3 to my skincare routine?

Apply a few drops after cleansing and toning, then follow with a moisturizer. The serum is designed for daily use; if you are new to retinol, start with every other night and increase to nightly as tolerated. Always use sunscreen each morning to protect the skin being renewed by retinol activity.

• Morning: cleanse, few drops of serum, moisturizer, and SPF.
• Night: cleanse, optional BHA toner, serum, and moisturizer.
• Begin with 2–3 nights per week and build frequency over 4–8 weeks.
• Avoid combining strong exfoliants on the same nights to reduce irritation risk.

Who is this for: numbuzin No.3 Blue Bio-Retinol Pore Refining Serum is intended for anyone seeking gentler retinol benefits—especially people with visible pores, rough texture, or sensitivity to traditional retinoids. It suits all skin types, including sensitive, oily, and combination skin, and is a practical next step for those ready to add retinol into a daily regimen while keeping barrier support and tolerability in focus.
