A short time one of my clients reported she had been using Vaniqa to suppress facial hair growth. It had worked to her satisfaction for several years, but suddenly strong side effects occured: strong burning and redness. After stopping using vaniqa she suffers from massive excess hair growth - fine but already terminal hair (not of vellus type), and a few slightly thicker darker hairs thrown in. The hypertrichosis is really "impressive": in the regions of maximum density (cheeks) the hair density exceeds that of an average male beard.
Luckily the hair is fine and can be killed by electrolysis fast and with few side effects.
