Topbec Lotion (100 ml) is a steroid-based lotion containing beclomethasone dipropionate, usually prescribed for inflammatory skin conditions like eczema or dermatitis. It is not a sunscreen or sun-protective medicine. Since your doctor in Panchkula prescribed something for vitiligo and sun exposure, the safest step is to confirm directly with your doctor or pharmacist that Topbec Lotion is indeed the exact product intended for your treatment. Using a steroid lotion incorrectly can cause side effects, so please do not start or continue it on your own until you have verified it and received instructions on safe use.
