    TLDR Asparagus racemosus root extract reduced sebum and pore size in men but not in women.
    The research investigated the effects of Asparagus racemosus Willd. root extract on sebum production and pore size. The extract, rich in polyphenolic compounds like quercetin, naringenin, and p-coumaric acid, significantly reduced the expression of steroid 5-alpha reductase gene (SRD5A) by about 45.45% and 90.86%. This led to a decrease in facial sebum production and a reduction in pore area in male volunteers after 15 and 30 days of treatment. However, this effect was not observed in female volunteers. The study, involving 42 volunteers (20 males and 22 females), concluded that A. racemosus root extract could be a potential anti-sebum and pore-minimizing ingredient for cosmetic applications.

      A person in their early 30s has been using finasteride for about 10 years and recently started oral minoxidil, vitamin chewables, and dermarolling to address hair loss. They noticed pigmented vellus hairs and potential regrowth, questioning if oral minoxidil is more effective than topical due to enzyme differences.
