Is picosecond laser suitable for treating dark underarms?

Genetics, friction, sweat, and other factors may lead to excessive melanin production by melanocytes, resulting in darkening of the underarm skin. Pico-second laser treatment can utilize specific wavelengths of light to penetrate the epidermis and directly target the epidermal or dermal layers, creating micro-explosion effects that break down melanin particles. This allows the melanin to be gradually cleared by phagocytic cells within the body, thereby reducing the activity and number of melanocytes.
