A curated trial kit from Numbuzin featuring the brand's No.5+ Glutathione Vitamin line — a high-performance brightening collection powered by glutathione and a vitamin complex to visibly fade dark spots, even skin tone, and deliver a luminous, glass-skin glow.

What's Included

• No.5+ Glutathione Vitamin Toner 30ml— A brightening toner that preps the skin with glutathione and vitamin actives, delivering the first layer of tone correction and radiance-boosting hydration to cleansed skin.
• No.5+ Glutathione Vitamin Serum 10ml — A concentrated brightening treatment serum that delivers a high dose of glutathione and vitamin C derivatives to visibly fade dark spots, inhibit melanin production, and restore an even, luminous complexion.
• No.5+ Glutathione Vitamin Dark Spot Cream 15ml — A brightening moisturizer that seals in the No.5+ routine's active benefits while providing sustained hydration and a luminous, dewy skin finish throughout the day.
• No.5+ Glutathione Vitamin Mask 27ml — An intensive brightening sheet mask that delivers a concentrated dose of glutathione and vitamin actives for a visible glow boost — ideal as a weekly skin reset or pre-event radiance treatment.

Why the No.5+ Line

Numbuzin's No.5+ Glutathione Vitamin line centers on glutathione — a master antioxidant that suppresses melanin synthesis at the source — combined with a vitamin complex including vitamin C derivatives for comprehensive, multi-pathway brightening. Using the full No.5+ system together maximizes the cumulative dark spot fading and radiance effect for visibly brighter, more even-toned skin.

How to Use

After cleansing, apply the toner, followed by the serum, and finish with the cream. Use the mask 1–2 times per week in place of or in addition to the serum step. Use morning and evening for best results. Always follow with SPF in the morning to protect the brightening treatment and prevent further UV-induced pigmentation.
