Every one should have this,

[This review was collected as part of a promotion.] Every one should have this, especially for day time skincare routine. I love the smooth finish. It's very good at hydrating and treating the skin. Give the skin a radiant finish. A little amount does it. The quality is top notch. You can never go wrong with this, as result is very visible with a few days.

I chose this serum because

[This review was collected as part of a promotion.] I chose this serum because of its hight quality ingredients and Cosrx's strong reputation. The formula feels lightweight and absorbs easily. Since I have only recently started using it, I will like to continue for at least one month before evaluating the product. So far my experience has been very positive.
