Is it very aggravating to remove coffee spots with laser

Hello, laser coffee spot removal mainly utilizes different wavelengths of laser light to selectively act on melanin cells in the dermis to achieve the principle of removing coffee spots. Only the diseased cells absorb the specific laser light, while the normal skin tissue is not damaged, so it will not leave scars. However, the premise of laser removal of coffee spots will not leave scars is to choose a regular specialized hospital, because if the operation is not correct, it will also affect the final results, and even leave scars.
