Numbuzin No. 5 Vitamin Boosting Essential Toner – 200ml

The Numbuzin No. 5 Vitamin Boosting Essential Toner is a first-step Korean brightening toner designed around a multi-layer anti-pigmentation system rather than a single brightening ingredient. Numbuzin stacks five active compounds — high-concentration Niacinamide, Liposomal Glutathione, stabilized Vitamin C, Arbutin, and the brand's proprietary MADEWHITE complex — each targeting melanin production and skin dullness through a different pathway. The result is broader, more consistent brightening than single-active toners can deliver, without the irritation associated with high-dose Vitamin C alone.

The texture is a lightweight, slightly viscous essence that absorbs quickly without stickiness or residue. It is fragrance-free, alcohol-free, and has passed skin irritation testing, making it appropriate for daily use on sensitive and acne-prone skin. For maximum effectiveness, Numbuzin recommends pairing it with the No. 5 Vitamin Concentrated Serum — a combination that the brand has clinically tested to improve brightening results by 133%.

Key Benefits of Numbuzin No. 5 Vitamin Boosting Essential Toner

• Clinically proven to reduce the appearance of dark spots by 18.12% within two weeks of consistent daily use
• Niacinamide at 50,000ppm suppresses melanin transfer to skin cells, regulates sebum, and strengthens the skin barrier simultaneously — addressing multiple concerns with a single active ingredient
• Liposomal Glutathione penetrates the skin cell membrane and works from within to reduce melanin synthesis at the source rather than only at the surface
• Stabilized Vitamin C (3-O-Ethyl Ascorbic Acid) delivers antioxidant protection against UV-triggered pigmentation while supporting collagen synthesis with daily use
• MADEWHITE complex at 20,000ppm — built around Madecassoside from Centella Asiatica — soothes while simultaneously addressing uneven tone, making it safe for reactive and post-acne skin
• 6-type peptide complex supports skin firmness and elasticity, making the formula functional for anti-aging concerns alongside its primary brightening role
• Fragrance-free, alcohol-free, cruelty-free — passed skin irritation testing and suitable for sensitive and acne-prone skin types

Skin Types and Concerns

• Oily and acne-prone skin: Niacinamide at high concentration regulates sebum production while Glutathione and Vitamin C address the post-acne marks left after breakouts resolve
• Dry and dull skin: Betaine, Panthenol, and Ceramide NP maintain hydration and barrier integrity, preventing the dryness that can accompany highly active brightening routines
• Sensitive and reactive skin: Fragrance-free, alcohol-free formula with MADEWHITE and Madecassoside calms while brightening — designed to be irritation-free with daily use
• Aging and uneven skin: 6-type peptide complex alongside Vitamin C and Adenosine supports collagen synthesis and skin elasticity, while the brightening actives address tone
