I used to have very bad acne. I took accutane when I was young (14) and the acne came back in different parts of my body. I am now 21 and my acne is a lot milder (except on my back where its cystic) but still present. I have extremely oily skin. I will eventualy use some accutane but I don't feel like dealing with an initial breakout.
Recently i started taking guggulsterrones. (I also have been taking B5 for 8 months) In the past week i have had ZERO acne. I would seriously suggest trying it. Obviously its not a cure like accutane beecause if you stop taking it your acne will come back, but i have never found anythin that cure all my acne, including back acne. I have been taking 128mg in the morning of synthetic guggul sterones and 15mg at night.
