Whereas in vitro experiments demonstrate that the addition of vitamin B6 and zinc to azelaic acid allows azelaic acid to be used in smaller quantities to inhibit the synthesis of DHT in the skin, there are absolutely no studies in regards to the absorption dynamics of topical vitamin B6. Exhaustive research and consultations with the pharmacology departments of many universities yielded no information concerning the absorption, efficacy or safety of topical vitamin B6.
