I have suffered with painful, cystic acne for five years. I had tried everything possible from diets, to supplements, skin treatments and antibiotics all of which failed to produce any results, I even went to several dermatologists who said they couldn't help me. I had almost given up on ever having clear skin until i came across estroblock after doing hours of research. At first I was skeptical because I had always been disappointed with products that claimed to 'work' but didn't, but I am so happy that I found estroblock. I have been on it for roughly three months and my skin has cleared up dramatically, no more painful cysts, no more throbbing, no more redness and I can eat whatever I want and still not break out! My skin has never been this clear! If you have acne, give estroblock a try, you will not be disappointed.
