Description

COSRX The Niacinamide 15 Serum is a concentrated treatment designed to address dullness, uneven texture, and minor imperfections through a stable 15% Niacinamide formula. The inclusion of Zinc PCA aids in oil control and pore appearance, while Acetyl Glucosamine and Trehalose provide moisture and support for the skin barrier. Allantoin soothes irritated skin, and Tocopherol adds antioxidant support. The result is a versatile serum suitable for regular use in both morning and afternoon routines, packaged in a convenient 20ml bottle for easy ongoing care.

How to use

After cleansing, during the serum phase, apply a few drops to the skin. Use fingertips to gently massage and absorb the serum, starting from the center of the face working towards the edges. This serum can be used in the morning and/or afternoon. If applied in the morning, be sure to use with a SPF of 30 or higher.

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.
