Product
Overview

numbuzin No.5+ Glutathione Vitamin Concentrated Serum (30ml) is a
high-potency brightening serum that leverages the powerful antioxidant and
melanin-inhibiting properties of glutathione, combined with a comprehensive
vitamin complex, to deliver visible skin brightening and tone-evening
results. It sits within numbuzin’s premium No.5+ extended line, designed for
those who want a step up from standard niacinamide brightening — targeting
deeper, more stubborn discolouration with a concentrated dose of glutathione
actives.

Glutathione has become one of the most sought-after brightening
ingredients in Asian skincare, particularly popular across South and
Southeast Asia where sun-induced pigmentation is a widespread daily concern.
Unlike some surface-level brighteners, glutathione addresses melanin
production at a cellular level, potentially offering more lasting brightening
effects with consistent use. The added vitamin complex supports antioxidant
defence and provides complementary brightening signals for a more
comprehensive and targeted treatment approach to stubborn
pigmentation.

Key Benefits

Glutathione helps inhibit tyrosinase enzyme activity, reducing
melanin production at a cellular level.
Vitamin complex (including vitamin C derivatives) supports
antioxidant protection and skin radiance.
Concentrated 30ml size delivers a potent dose of actives in a
compact, travel-friendly format.
Helps visibly improve dull, uneven skin tone and reduce the
appearance of dark spots over time.
Lightweight serum consistency layers cleanly under moisturiser
without disrupting other products.

Key Ingredients

Glutathione is a naturally occurring antioxidant tripeptide that
plays a key role in regulating melanin synthesis. It inhibits tyrosinase, the
enzyme responsible for melanin production, helping to visibly reduce
pigmentation with regular topical application. When paired with vitamin
actives that provide additional antioxidant coverage and skin radiance
support, the combined effect delivers a multi-pathway brightening result that
works well for tan, hyperpigmentation, and dark spot concerns common in
sun-exposed skin types.

Who It’s For

Best suited for those dealing with stubborn dark spots, tan lines,
or persistent hyperpigmentation who want a concentrated glutathione-powered
brightening serum. Suitable for all skin types, especially those in
sun-intense climates like Bangladesh where deeper pigmentation is a frequent
daily concern.
