Super picosecond freckle removal is an upgraded version of laser freckle removal, and its therapeutic effect is more obvious and effective. Super picosecond freckle requires three to six treatments, and the reason why it needs so many times is to have a better freckle effect. Pay attention to hydrating and moisturizing, pay attention to sun protection after operation, do not apply sunscreen on the day of treatment, and pay attention to physical sun protection. Q-switched laser and picosecond laser are commonly used in freckle removing laser. The pulse width of Q-switched laser belongs to nanosecond and picosecond laser belongs to picosecond, so it is called picosecond laser. Picosecond laser will be shorter than nanosecond laser, so it means that more energy can be emitted in a shorter time. Picosecond laser freckle removal effect is better, and it needs less times. Generally, 1 2 is needed to treat freckles and senile plaques, and chloasma is more. Laser freckle should not be over-mythical picosecond laser, it is only an upgrade of early nanosecond laser.
