Thanks for the query,
rosaceae is an inflammatory condition of face,
Mainly affecting the face,
The vessels get dilated and hence face become red.
She need treatment with topical anti inflammatory like metrogyl
cream to be applied daily in night
Doxycycline is also helpful.

Please meet a dermatologist
