numbuzin No.3 Retinol Serum — Blue Bio-Retinol Pore-Refining Serum, 30ml with 10% Niacinamide & Peptides

numbuzin No.3 is a gentle, pore-refining retinol serum that combines blue bio-retinol with 10% niacinamide, peptides and BHA to smooth texture and tighten pores with reduced irritation.

This lightweight serum is formulated as an entry-friendly retinol treatment that targets enlarged pores, uneven texture and the early signs of laxity. Instead of traditional yellow retinol alone, the formula blends a bio-based blue retinol system with encapsulated retinol for steadier delivery, paired with a high-dose niacinamide to support tone and barrier function. Clinically tested for pore-related improvements, it’s crafted to be suitable even for skin that is new to retinol routines.

How quickly will I notice my pores and texture improving?

Results vary by individual, but users typically see measurable changes in pore appearance and skin texture after consistent use over several weeks. The combination of blue bio-retinol and 10% niacinamide is designed to act on pore structure and surface smoothness gradually and with fewer irritation risks than some retinol-only products.

• Visible smoothing often appears within 4–8 weeks of regular application.
• Niacinamide helps even tone and reduce the look of pores while strengthening barrier resilience.
• Encapsulated retinol aims to release actives over time to limit abrupt irritation.

Is this serum suitable for retinol beginners and sensitive skin?

Yes — the serum is formulated with sensitivity in mind, making it a good option for those new to retinol. The blue bio-retinol system and encapsulation techniques moderate the delivery of retinol, and the supportive ingredients help calm and fortify the skin.

• Gentler bio-retinol blend reduces immediate irritation risk compared with conventional retinol.
• Niacinamide at 10% assists barrier repair and improves tolerance to active treatments.
• Recommended to patch-test and introduce gradually if you have reactive skin.

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

Apply a few drops to clean, dry skin once daily or twice depending on tolerance; follow with moisturizer. Use sunscreen every morning while using retinoid products to protect treated skin from UV sensitivity and maintain results.

• Start with every other night, then increase frequency as your skin adapts.
• Layer under moisturizer; avoid mixing with other strong actives like high-strength AHAs on the same application.
• Always finish morning routines with broad-spectrum SPF.

What are the key actives and what do they do together?

The serum combines blue bio-retinol, encapsulated pure retinol, niacinamide, peptides and a low-level BHA to address pores, texture and firmness without harshness. Each component targets different aspects of skin health to promote a more refined, resilient complexion.

• Blue bio-retinol + encapsulated retinol: steady retinoid delivery aimed at minimizing irritation.
• 10% niacinamide: improves tone, supports barrier function and reduces visible pore prominence.
• Peptides: assist in the appearance of firmness and skin elasticity over time.
• BHA: gentle exfoliation to clear pore buildup and enhance texture smoothing.

Who is this for? numbuzin No.3 is crafted for people seeking a beginner-friendly retinol step that targets enlarged pores, uneven texture and early laxity without the typical harshness of traditional retinol treatments. It suits most skin types, including those prone to sensitivity, provided users introduce it gradually and protect their skin with daily sun protection. If you want a science-forward solution that balances effectiveness with tolerability, this serum is designed to be a measured way to add retinoid benefits into your routine.
