[Numbuzin] No.5 Vitamin Concentrated Serum 30ml

The Numbuzin No.5 Vitamin Concentrated Serum 30ml is a focused brightening ampoule designed to even skin tone and reduce the appearance of hyperpigmentation. It combines a powerful antioxidant lineup—glutathione for brightening and protection, plus multiple forms of vitamin C—to support a more radiant complexion without heaviness. Enhanced with tranexamic acid and alpha-arbutin to target discoloration, and complemented by niacinamide for moisture and barrier support, this serum aims to deliver clearer, more luminous skin over time. The formula is paired with hydrating and soothing ingredients like hyaluronic acid, ceramides, and panthenol to help maintain a healthy, resilient skin barrier.

Designed for daily use, it addresses uneven skin tone and dullness with a thoughtful blend of skincare staples rather than a single "miracle" ingredient. This makes it suitable for those seeking a concentrated treatment that fits into a straightforward routine while targeting pigment concerns and complexion brightness.

Sunscreen & SPF Products in Canada

Unfortunately due to regulations by Health Canada we are unable to offer any Korean sunscreen or SPF products to Canadian customers.

We are working with Health Canada to obtain Federal approval for these items, but it's a lengthy process.

We apologize for the inconvenience and will let you know as soon as this changes!

Why does my product look different from the photos on your site?

Korean beauty brands update their formulas and packaging regularly - sometimes several times a year - and these changes often happen faster than we can update every listing. We do our best to keep product pages current, but what you receive may have a newer formulation or updated packaging. The core product and its function remain the same. If you'd like to verify what's currently in stock before ordering, reach out to us at info@kbeauti.ca and we'll confirm for you.
