Could Finasteride Use Cause Wrinkles?

Finasteride works by disabling the enzyme 5-alpha-reductase, thereby inhibiting the conversion of testosterone into DHT. While finasteride does have potentially high-risk side effects, I am not aware of it as a cause of premature aging.

Finasteride is not known to cause wrinkles.  At a dose of 1mg per day it is marketed as Propecia for male pattern hair loss.
