It doesn't matter. It can be seen from the principle of laser treatment of freckles.

The principle of laser treatment of freckles: without damaging normal skin tissue, a laser beam with a specific wavelength penetrates the epidermis and dermis (just like light penetrates the glass) and enters the lesion to treat the pigment in the lesion. When laser is used to treat freckles, the pigment of freckles is completely broken and disintegrated under the irradiation of strong laser, and then dissipated by itself, thus being cured. Compared with traditional methods such as freezing and chemical peeling, laser treatment of freckles has absolute advantages. It is not only effective, but also rapid and has few adverse reactions.
