NUMBUZIN No.5 Vitamin Concentrated Serum 30ml

Korean Vitamin Skincare at Its Most Concentrated

NUMBUZIN No.5 Vitamin Concentrated Serum is a high-performance brightening serum from one of South Korea’s most celebrated skincare brands, delivering a potent blend of vitamin-derived actives in a lightweight, fast-absorbing formula. The No.5 serum is formulated around a multi-vitamin complex that targets uneven skin tone, dullness, and the early signs of oxidative ageing — working at the cellular level to promote a visibly brighter, more luminous complexion with consistent use. The concentrated formula means a little goes a long way, making the 30ml bottle a generous supply for daily application.

NUMBUZIN’s approach to skincare is rooted in the Korean beauty philosophy of layering lightweight, active-rich formulas that work synergistically to address multiple skin concerns simultaneously. The No.5 serum sits comfortably within any existing skincare routine — applied after cleansing and toning, before moisturiser — and is suitable for most skin types including sensitive skin. The texture is silky and non-sticky, absorbing quickly without leaving residue, and the formula is free from the harsh irritants that can compromise skin barrier integrity over time.

At Calm Era, we curate skincare with the same editorial rigour we apply to our supplement range — selecting only products that combine genuine efficacy with considered formulation. NUMBUZIN No.5 Vitamin Concentrated Serum is a standout in the K-beauty brightening category, offering the kind of visible, sustained results that make it a worthy addition to any serious skincare routine. Radiance, concentrated.
