Oily Skin After Taking Propecia?

Dr. Rassman,
Thanks for your fine blog and the wonderful service it provides. In your experience, how common is oily skin as a side effect of propecia, when does it present, and does it resolve itself over time under continued treatment. I took my first dose of Propecia this morning and even now (12 hours later) my skin seems much more oily than normal.

30 years old. Thinning in front and just starting to thin in the back.

Thanks

I am unaware of Propecia (finasteride 1mg) producing oily skin, but there is some logic that it could make the skin less oily. Propecia blocks dihydrotestosterone (DHT); oily skin is caused by DHT. Here’s a page that has more info about oily skin — Dermadoctor.com
