Review of a serum I bought with my own money

COSRX The Vitamin C 23 Serum

Gently shake from side to side 1-2 times, apply an appropriate amount to your face, and roll with your fingertips from the inside out to help absorption.

I like that it absorbs lightly. Although I have sensitive and dry skin, it has a good soothing effect. It corrects skin tone and adds radiance. It also provides elasticity and moisturizing benefits.
