retin-a and b5 safe together?

Recommended Posts

i just started Dr. Perricone's acne prescription but i'm continuing retin-a micro. also stopped the Doryx since i'm taking so many supplements. Dr. P says B5 is good but has anyone tried it with Retin-A micro to get rid of the oiliness that comes from using RAM over an extended period of time?

Megadosing with B5 alone isn't exactly safe. Nobody has ever studied it's side effects, only its acne fighting properties. Dr. Perricone recommends 10 to 250 mg of B5 in his supplement list, but Dr. Leung's original study on B5 recommends you take 10 grams a day, which is 40 times that much.

I took B5 for 15 days, during which i experienced nearly constant diarrhea and upset stomach. During the second week my scalp became drier, and my hair started thinning. All of these symptoms have resolved themselves since i stopped taking it.
