Greetings - mole marks as in - have u already got moles removed through some kind of proedure or surgery? You'll need skin lightening creams for a specified duration to reduce the marks , and this could also be dealt with chemical peeling. Also you must use a sunscreen to prevent darkening of the spots. For scars, creams may not work n you may need procedures like microneedling, microneedling rf, fractional lasers,etc. Hope this helps. Warm regards.
Send in your pictures if you need further assistance. Or see a dermatologist near you and discuss the same with him.
