Hello ! It's important to avoid laser treatment if you have a tan as it can increase the risk of skin damage and pigmentation issues. However, there are other options for removing flat moles or freckles. One option is to have the mole or freckle surgically removed by a dermatologist. This is typically done under local anesthesia, and the skin is sutured closed after removal. Another option is to have the mole or freckle removed using cryotherapy, which involves freezing the lesion with liquid nitrogen. This treatment is typically quick and does not require anesthesia, but there is a risk of scarring or pigmentation changes. It's important to note that some flat moles or freckles are harmless and may not require removal. However, if you're concerned about a particular lesion, it's best to consult with a dermatologist who can evaluate the area and provide guidance on the best course of action. Best of luck !
