Review (3/5): not sure..
I gave it a 3 bcz when I was trying it its gel is smooth, but since I have sensitive skin I was scared to try on my face, so I tried on the back of my one hand and one inside of my arm, As in the pic, the red part is where I put the product, it feels burn in my arm, I can imagine if it was on my face. So for the effect, it really dries my arm and my hand, so I won't give it a try to my face. Hope to return the product if it's possible.
