Hello and Welcome to 'Ask A Doctor' service. I have reviewed your query and here is my advice.
As per your complain I would like to inform you that
Betnovate N cream is a steroid based cream
Betamethasone and Neomycin as active ingredients.
Steroid creams initially shows wonderful effects on face by reducing pigmentation and brightening the face..
But long term use has severe side effects like skin thinning, pimples, inflammation, rashes, itching, excess hairgrowth and dilated veins under the skin..
Also on long term use the skin becomes addicted or dependant on steroids and once the use is suddenly stopped, there are withdrawal side effects and it is the same thing that you are facing now that is increased pigmentation, rashes, swelling, redness etc..
I would suggest you to
consult a Dermatologist who can evaluate you clinically and also advise you a low potency steroid cream that has to be used for a week regularly and then gradually tapering down the use and then will be stopped gradually..
It will help in preventing side effects of sudden withdrawal..
Once the side effects resolve completely you can start using her safe
depigmentation creams and facewash like
salicylic acid and
glycolic acid containing facewash,
kojic acid, arbutin and glycolic acid creams etc..
You can apply cooled aloevera gel on face to soothe the skin..
Hope I have answered your query. Let me know if I can assist you further.
