Ive been using Betnovate N cream and noticed my face became fairer, but as soon as I stopped using it, my face got darker again, and now I also have dark circles. Could you suggest a good cream for fairness and also help me with tips to improve the skin on my back?

To address the darkening and dark circles on your face, you can try using a cream containing Hydroquinone, Tretinoin, and Mometasone in the night for a limited period under the guidance of a dermatologist. For fairness, you can use a cream containing Kojic Acid, Arbutin, and Vitamin C in the morning. Remember to always use sunscreen during the day to protect your skin.
