PicoSure
The PicoSure laser converts energy into pressure rather than heat. It immediately eliminates melasma at its root beneath your skin. The actual treatment is quick and a little painful. You can feel a stinging sensation on your skin that is comparable to a rubber band snapping. According to one study, PicoSure lessens melasma without causing other negative effects like hyperpigmentation [3].
Q-Switch
The Q-Switch laser, also known as The Spectra®, penetrates your skin with energy to break down melanin into smaller fragments that are then eliminated by your body. Your hair may also be bleached using Q-Switch, and the procedure may sting.
