In this past year I've developed hormonal acne which I have never had before in my life. I tried a few other brands before I found Oxygen and I now won't use anything else. This gel works so well and so fast at drying up spots and clearing up redness. When I have a lot of spots that are quite active I use this product morning and night (after my toner, I apply this gel then let it dry for 5 or 10 mins, and then apply my moisturiser) and it works great. I'm on my 4th repurchase of this product because it's seriously amazing and takes control of all the spots for me.
