Prolonged application of potent steroid like betnovate
over face is very harmful.
It can cause whitish striae over face ,telangiectasia
or visible blood vessels, thinning of skin , excessive hair growth
, bleeding patches.
I suggest you to immediately stop betnovate application .
Consult a dermatologist
who will help with the symptoms of steroid withdrawl.
use anti allergic drugs and good quality moisturizer on face.
hope this helps.
