Is picosecond laser suitable for treating dark underarms?

　　Generally, picosecond lasers are more suitable for treating dark underarms, although results may vary from person to person. The general reference price for picosecond laser treatment is 2000-5000 yuan per session, and noticeable improvement can typically be seen within 7-15 days. It is recommended to visit a formal hospital and undergo the procedure under the guidance of a qualified physician.

　　Genetics, friction, sweat, and other factors may cause melanocytes to produce excessive melanin, leading to darkening of the underarm skin. Picosecond lasers can utilize specific wavelengths of light to penetrate the epidermis, directly targeting either the epidermal or dermal layers. This creates a micro-explosion effect that breaks down melanin particles, allowing them to be gradually cleared by phagocytic cells in the body, thereby reducing both the activity and number of melanocytes. This process helps lighten or remove melanin deposits in the underarm area.

　　Picosecond laser treatment is generally considered safe, but it should be performed by a qualified physician at a legitimate medical facility to minimize risks. Additionally, if the patient has compromised skin barrier function, inflammation, or infection, picosecond laser treatment should not be used on the underarm area to avoid worsening skin damage or delaying the healing process. Moreover, multiple treatment sessions are usually required to achieve optimal results, with each session spaced 4-6 weeks apart.

　　After undergoing picosecond laser treatment, patients may experience temporary side effects such as redness, swelling, or mild pain, which typically resolve on their own. A small number of patients may feel a burning or warm sensation on the skin, but this usually subsides quickly within a short time.
