Reveal Brighter, More Even-Looking Skin
The Numbuzin No.5+ Glutathione Vitamin Concentrated Serum is designed to target dullness, uneven tone, and post-blemish marks while supporting long-term skin health. Powered by a potent blend of brightening ingredients, it helps restore radiance and promote a smoother, more luminous complexion.
Unlike harsh brightening treatments that can leave skin feeling dry or irritated, this lightweight serum combines advanced vitamins, antioxidants, and barrier-supporting ingredients to deliver visible results while keeping skin comfortable and hydrated.
With consistent use, skin appears brighter, healthier, and more balanced.
Advanced Brightening Meets Barrier Support
This multi-action formula combines Glutathione, Niacinamide, Alpha-Arbutin, and multiple forms of Vitamin C to help visibly improve skin tone and reduce the appearance of discoloration.
At the same time, Bifida Ferment Lysate, Ceramides, Beta-Glucan, and Panthenol work to support the skin barrier and lock in hydration, helping skin maintain a healthy, resilient appearance.
The result is skin that looks clearer, smoother, and naturally radiant.
