Don't expect anything but a decrease in oil production.
If you're like me it's worth what its made for: shutting your sebaceous glands up! (decrease oil production)
What's "like me" ??!: Pale, insanely oily (as in every hour you need one of those blotting sheets), large pores, lots of blemishes, like if I breakout it leaves a mark every time for like a whole year or longer, scarring, recently hormonal breakouts (during PMS then clears up just in time for next PMS), some cysts (from excess oil), skin is so sensitive I can touch my face with water and I'll break out.
It helped with the oiliness so I am assuming in the long run it will help with cysts, I think I will need half as many blotting papers which is awesome, I will still break out because of my hormones so I won't be completely new-blemish free. It doesn't seem to be helping with any other issue I have. Skins smoother after the peeling ends because hello I just shed a layer, but other than that there's nothing left to do but take care of it as best I can and hope that my make up for work doesn't ruin the process I just went through.
One thing that bothered me was that I don't get whiteheads and I got some, maybe a dozen, and little tiny spots here and there. The white heads hurt and it was as if they were getting pushed out of my face by the treatment. But eventually it goes away.
They will tell you it will help with other things like some conditions I have, but thats not what its made for so just go in knowing that you will clean the oil spills, which I think is really important to start off with.
