This forum is for guys that QUIT THE DRUG ALREADY. If you are still taking it, get off it and most likely things will be fine.
You are inhibiting 5AR2/DHT in 5AR2-dependant tissues (and to a lesser extend 5AR1 as well), so don’t expect anything to improve as long as you continue to ingest the medication. The dry skin is a result of this process.
If you read up on the role of androgens, such as DHT, in the role of sebum and oil production, and acne, you’ll see there is in fact a connection there… so when you inhibit DHT, you may experience the opposite.
