Cos de Baha - haika review for Retinol 2.5% Serum + Vitamin E

This retinol had a good result on my skin. I had a milia under my eye (orbital part), and i used this retinol since they claimed that the product could rid off the milia. That is so true, really. After 2-3 weeks, i noticed my milia gone. It also made my skin better than before, because actually this is my very first retinol, and i didn't have serious issue though it has quite high percentage.
