Tenovate Gn is a very strong steroid
cream and is not indicated for use over face and you have used it for 4 yrs over your face. The complaints of redness irritation dryness is all because of its prolonged use and sudden discontinuation.
Right now I would just advise you to use a calamine
and aloe vera
based lotion (calosoft etc) over face.
Also please meet a dermatologist
nearby for skin examination and further management.
