What is Numbuzin No.5 Vitamin Concentrated Serum?

The Numbuzin No.5 Vitamin Concentrated Serum (30ml) is a high-potency vitamin C treatment serum in the No.5 line — delivering a concentrated dose of Numbuzin's multi-form vitamin C complex alongside niacinamide, brightening botanical extracts, and barrier-supporting ingredients. Designed for daily targeted treatment of hyperpigmentation, melasma, dull skin, and overall radiance improvement, this serum represents the most concentrated single-step vitamin C brightening treatment in the Numbuzin lineup. For Pakistani women investing in a single brightening serum to address sun damage and uneven skin tone, the No.5 Vitamin Concentrated Serum is the core product in the Numbuzin No.5 system.

Key Ingredients & Benefits

Multi-Form Vitamin C Complex (Ascorbic Acid + 3-O-Ethyl Ascorbic Acid + Ascorbyl Glucoside): Three complementary vitamin C forms working in concert — pure ascorbic acid for immediate potent antioxidant and brightening action; 3-O-Ethyl Ascorbic Acid for highly bioavailable, stable brightening with good skin penetration; and ascorbyl glucoside as a slow-release form that provides sustained vitamin C delivery throughout the day. This triple-vitamin C approach maximizes the range of brightening mechanisms engaged compared to a single-form vitamin C serum, producing more comprehensive results on Pakistan's UV-exposed and pigmentation-prone skin.

Niacinamide (7%): At 7%, niacinamide works powerfully alongside the vitamin C trio — blocking melanin transfer, regulating sebum, strengthening the skin barrier, and providing anti-inflammatory effects. 7% is above the standard 5% found in many products and delivers noticeably stronger results for Pakistani women managing significant hyperpigmentation, melasma, or post-acne marks.

Tranexamic Acid: A brightening active clinically proven for melasma treatment, tranexamic acid works through a different mechanism than vitamin C and niacinamide — inhibiting the interaction between melanocytes and keratinocytes that drives melanin overproduction. Its inclusion in this formula provides a third brightening mechanism, creating a triple-pathway approach that is particularly effective for stubborn melasma that responds inadequately to vitamin C and niacinamide alone.

Ferulic Acid: Doubles the antioxidant efficacy of the vitamin C in the formula — a synergistic combination that is one of the most well-documented interactions in cosmetic chemistry. Ferulic acid also provides its own UV damage protection and has mild brightening properties. The result is a significantly more stable and effective vitamin C formulation than vitamin C without ferulic acid.

Hyaluronic Acid & Squalane: Balance the high-active formulation with deep hydration and barrier-supportive emolliency — ensuring the concentrated actives do not cause dryness or irritation during extended treatment use.

Skin Concerns This Addresses

How to Use Numbuzin No.5 Vitamin Concentrated Serum

Apply 2–3 drops after toner and before moisturizer, morning and evening. In the morning, always follow with SPF50+ — vitamin C and tranexamic acid can increase photosensitivity and the brightening actives require UV protection to avoid UV-induced reversal of their effects. For Pakistani women layering multiple Numbuzin products: Numbuzin No.3 Toner → Numbuzin No.5 Vitamin-Niacinamide Pad → this serum for a comprehensive brightening routine. The 30ml serum provides approximately 2 months of twice-daily use with a standard 2–3 drop application. Store away from direct sunlight and heat — refrigeration optional but extends vitamin C stability and potency.
