I have to share this with everyone I can. I have had Acne problems for the last ten years, and I've tried everything. I've begun to be cynical about any new products I see, but I usually try them anyway. I finally started doing some research on the internet and came upon a research study on B5/Pantothenic Acid. I decided to give it a try. I have been taking 8 g per day, 2 g less than the research suggests, but I only weigh 100 lbs. Anyway, I take four (4) 500mg capsules with each meal and again at bedtime, which is 16 pills a day. I hate that part, but I cannot believe my skin. Every blemish I had is gone! and I've only been on it for a week. I have been on the sugar-free diet for several months and no results like this. In just a week, the oil production has been cut to a fraction. I hope you all heed my advice and start this supplement today; it's just incredible. You can get Pantothenic Acid at GNC or any comparable place.
