AcneFree OVERNIGHT RESULTS gel is one of the best acne products I have tried but I have mild acne. I always have a few zits about to appear on my face and usually in the same places. The great thing about the OVERNIGHT formula is that it is best at keeping those "just under the skin" zits at bay. Sometimes it does work overnight on my minor blemishes--my skin doesn't look flawless but it is enough to coverup with light makeup. But if you have a major volcano on your face, you WILL have to give it a few days to dry up. Speaking of drying...it can dry up your skin and make it red but not NEARLY as bad as some other acne medications I have tried. Also you only get a little bit in each tube and if you run out and stop using it, your skin will go back to the way it was before. Even if you don't have zits, you have to keep putting on a thin layer to prevent them and if you don't, they WILL crop up. Also, the new formula has little white flecks that make it hard to put on under makeup unless you pick them off. It definitely is worth your while though because it is clear and goes under makeup easily aside from the new white flecks.
They also seem to be screwing around with the formula which is unfortunate because the original one worked best. The newest sensitive formula or severe AcneFree gel formulas are AWFUL. The sensitive one did literally NOTHING and the severe one gave me an awful rash that itched for a week and bleached out my clothes.
So, in short. This OVERNIGHT formula works VERY well but will stop working when you stop using it. Oh well, at least it is cheap. The rest of the AcneFree gel treatments are crap.
