I use the COSRX Line
Nancey C. — 5 out of 5 stars
[This review was collected as part of a promotion.] I use the COSRX Line of skin care products exclusively and the Advanced Vitamin C 23 has been part of my AM skin routine for over two years now. I feel like it has really helped even my skin tone and it’s great for my décolleté area, especially during summertime when sun spots begin to appear. I have had none since I started using this product.
