Very good serum for oily skin, helps to prevent breakouts, i've seen improvement in 1 week after using this. I was skeptical at first of revolution skincare because often makeup companies are just bad at formulation in skincare and use a lot of toxic ingredients you can also find in makeup. But this one was a good find, not too pricey for what it offers actually, and because the inkey list is hard to find, ship and more expesive, this one is a good alternative for the tranexamic acid you also cant easily find. Overall very happy and repurchased this❤️
