Pronexin is a treatment for acne. But read some pronexin reviews before you buy the product. As far as I could found out there are several contradictory opinions by different people – some saying that it works only for people with mild acne, some even saying that it doesn’t work (I read it in a hubpage article. hubpages are popular but are all the authors in it trustworthy? lol..). So you guys should so your own home work..
