Do try it: after doing antibiotics for some time (killed my stomach and didn't help), duac, tezorac, etc you name it, I accidentally came across this vitamin and my skin is finally getting back to normal!!! I'm in my 30 and always had problems with acne but two years ago, something out normal happened: the breakouts were all over my face, very painful and never ending. I tried both dermatologists and natural remedies - all in vain. My goal at that point was just to contain them, knowing perfectly well that my face will never look the same.
But 6 months ago, I first tried the regimen: cleaanser and benzoyl peroxide are great but moisturizer stings like hell and doesn't help with dryness. My skin was getting better or rather under control BUT it is only when I started taking 4x500mg of Pantothenic Acid (B5) I stopped having new break outs!!!
Right now, I use [link removed] cleanser, peroxide, Glycolic acid moisturizer (works great) + 2-4 capsules of 500mg of Panthothenic Acid. I still have occasional break outs BUT considering how bad it was, I consider this a miracle. All of my friends tactfully notice that my skin has gotten so much better, although I still have all the scars! I'm working on it now but at least there is some light at the end of the tunnel!
DO TRY this vitamin. I've read the reviews and was concerned about the hair loss. I was willing to take my chances and I'm GLAD I did. No side affects! I try to minimize the dosage now when I'm doing better but still afraid to stop taking it altogether (I'm that paranoid of acne coming back!)
Hope it'll help you as well!
