The document discusses 5a reductase inhibitors and their potential use in treating acne. There are two types of 5a reductase isozymes, type 1 and type 2, which are involved in endogenous production of DHT. The document also explores other factors like insulin, IGF, SHBG, and herbal extracts that may help regulate hormones involved in acne pathogenesis. Two product formulations are highlighted that utilize plant extracts shown in research to help balance hormones: a serum containing green tea, saw palmetto, and other extracts, and a magnolia honey cream containing resveratrol.
