A COSRX skincare set pairing the Niacinamide 15% Serum with the Peptide Booster Toner (six peptides), used together after cleansing.
Product details
Two COSRX steps designed to work together
This set layers a peptide toner under a niacinamide serum, so the toner preps the skin before the more concentrated step. COSRX presents it as a way to get more from the Niacinamide 15% Serum, and the packaging makes it an easy gift for someone who enjoys Korean skincare.
What each bottle brings
The Peptide Booster Toner contains six peptides with hyaluronic acid and allantoin, aimed at the look of elasticity, fine lines, pores and radiance. The Niacinamide 15% Serum pairs niacinamide with zinc PCA to help reduce the look of excess oil and refine texture.
What comes in the pack
One COSRX Niacinamide 15% Serum and one COSRX Peptide Booster Toner, in a box measuring about 18.8 x 9.6 x 5.2 cm and weighing around 358 g. Made in Korea.
How to use
After cleansing, apply 2-3 pumps of the toner to the face, avoiding the eye area, and pat gently to help it absorb. Follow with 2-3 drops of the serum, then your usual moisturiser if needed.
Before you choose
Patch test on the body before using either product on the face, and go ahead only if there is no irritation after 24 hours. If irritation occurs, consult a doctor straight away. Korean-market product: packaging may show Korean text.
