Description

Description:

The COSRX Niacinamide 15 Serum stands out as a highly concentrated solution expertly designed to combat acne and dark spots with its powerful blend of ingredients. Boasting a substantial 15% niacinamide, this serum works wonders in calming breakouts, controlling excess sebum, and refining congested pores. The inclusion of N-acetylglucosamine delicately exfoliates the skin, effectively fading hyperpigmentation, while zinc PCA ensures a balanced oil-water equilibrium, inhibiting inflammation and supporting skin recovery.

This serum is perfectly suited for all skin types dealing with blackheads, whiteheads, and enlarged pores, this serum not only regulates sebum but also smoothens rough skin texture and improves the appearance of acne scars. Its formula's careful synergy of ingredients makes it a potent solution for total acne control, delivering a comprehensive solution to congested pores, excess oil, and rough skin texture.

Recommended for: All skin types.

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.

Good to know

Questions, answered

Everything about this product, shipping and returns.

Is this product 100% authentic?

Yes. Every product is sourced from official Korean distributors, arrives sealed and is checked for expiry dates before it ships. We never buy grey-market stock.

How fast will I receive my order?

Order before 23:45 on a weekday and it leaves our warehouse the same day, with tracking. Delivery usually takes 1 to 4 working days in Belgium, the Netherlands and Germany and 2 to 6 working days elsewhere. We ship worldwide.

Do I pay customs or import duties?

Not in the EU: prices include VAT and there are no extra charges at the door. Outside the EU, local import duties may apply and are paid by the customer.

How does the bundle discount work?

Add any 2 products to your bag and 10% comes off everything. Add 3 or more and it becomes 15%. It is applied automatically, no code needed, and you can mix brands.

Can I return it if it does not suit my skin?

Unopened products can be returned within 14 days for a full refund. For hygiene reasons we cannot take back opened skincare. Not sure it fits your skin? Message us before you order and we will tell you honestly.

How do I use it in my routine?

Cleanser, toner, serum or essence, moisturizer, then sunscreen in the morning. Introduce one new product at a time and give actives 4 to 8 weeks. Take the skin quiz for a routine built around your skin.
