Assalamu alaikum wa rahmatullahi wa barakatuh, if a woman wears niqab and only her eyes show, is she allowed to beautify and shape her eyebrows for husband since only he will see her eyebrows?

Ustadh AbdulAziz al-Haqqan

The Nina shouldn't show the eyebrows and cheeks, so all of this must be covered only the eyes show nothing else.
