Numbuzin No.3 Blue Bio-Retinol + Niacinamide Serum 30ml

The Numbuzin No.3 Blue Bio-Retinol + Niacinamide Serum combines two powerful actives to brighten skin and refine pores. Its gentle retinol formula is designed for daily use without irritation. Skin looks visibly brighter and more even within 3-4 weeks of consistent use. This serum is suitable for all skin types, including sensitive.

Key Ingredients

• Niacinamide (5%): Regulates sebum production and fades post-acne marks. You will notice visibly smaller pores and a more even skin tone within 3-4 weeks of daily use.
• Blue Bio-Retinol (1%): A gentle form of retinol that speeds up skin cell turnover and improves skin texture. It reduces the appearance of fine lines and wrinkles without causing irritation.
• Hyaluronic Acid: Draws water into the skin from the environment and locks it in. Skin feels plumped and stays hydrated throughout the day without feeling heavy.

Skin Concerns Addressed

• Primary: Dark spots, uneven skin tone, enlarged pores
• Secondary: Fine lines, dullness, rough texture
• Supporting: Redness, sensitivity, dehydration

This serum is formulated specifically to target hyperpigmentation, pores, and early signs of aging. If your main concern is dark spots or uneven texture, this addresses it directly. For deep wrinkles or loss of firmness, pair with a stronger retinol product.

Why This Serum Works

This serum combines niacinamide and a gentle form of retinol to brighten and refine skin without causing irritation. It is designed for daily use, even on sensitive skin.

The blue bio-retinol is a stabilized form of retinol that is less likely to cause redness or peeling. It still delivers the benefits of retinol, such as improved skin texture and reduced fine lines.

Hyaluronic acid creates an immediate hydration lock from the first application, keeping skin supple between steps and making the niacinamide and retinol absorb more effectively.

Together, these ingredients create a multi-action formula that brightens, refines, and hydrates in one serum step.

Texture & Absorption

This serum has a lightweight, gel-like texture that spreads easily without feeling heavy or sticky. It absorbs within 30-45 seconds, leaving a smooth, slightly dewy finish that layers well under moisturizer and sunscreen. The formula doesn't pill when buffered with other products, making it ideal for morning routines where you need multiple layers to sit cleanly.

What to Expect

After first use: Skin feels immediately more hydrated and plumped. The texture absorbs quickly without any stickiness or residue.

Week 1–2: Fine lines look less pronounced, especially around the eye area. Skin feels more resilient to the touch.

Week 3–4: Visible improvement in skin brightness and evenness. Pores appear smaller and less noticeable.

After 6 weeks: Consistent reduction in the appearance of dark spots, with noticeably smoother and more radiant skin overall.

How to Use

1. After cleansing and toning, dispense 2-3 drops onto your fingertips.
2. Warm the serum between your palms, then gently press into your face and neck.
3. Pat lightly until fully absorbed, then follow with moisturizer.
4. Use morning and evening as part of your daily routine.
5. Pro tip: For faster brightening results, layer this serum under Vitamin C in the morning and a richer moisturizer at night. Consistent daily use over 6+ weeks delivers the most visible change.

Best Paired With

Morning: Layer under Vitamin C serum for enhanced brightening, or use alone before SPF 50+ sunscreen to prevent new dark spots from forming.

Evening: Pairs well with a hydrating toner or peptide cream. Apply niacinamide first, wait 2 minutes, then apply other actives. The barrier-strengthening effect helps minimize irritation from stronger treatments.

Avoid pairing with: Nothingniacinamide and retinol are highly compatible and work well with Vitamin C, AHAs, and peptides.
