Hello Mr. lybrate-user
First of all STOP using betnovate
for skin lightening. It is a STEROID and has many side effects. I request you not to apply any cream on your own and consult a dermatologist.
There are many good skin lightening creams available in the market which I can prescribe and they do not have any side effects. I need to see your skin colour and type for doing this.
You can start a private consult for that.
Meanwhile start using a good sunscreen of atleast 15 SPF
Take care :)
