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.

Wonderful

[This review was collected as part of a promotion.] I have only used this for about a week and I like how it absorbs nicely without leaving a sticky film. Leaves my skin soft. Too early to see any changes, but I like it so far

I really like this serum.

[This review was collected as part of a promotion.] I really like this serum. I don’t purchase it regularly because I’m a bigger fan of the Advanced Vitamin C 23 serum, and there are so many hours in the day!

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.
