Introduction
Under normal circumstances, the principle of picosecond laser treatment for freckles is mainly based on the laser's high energy and precision. If necessary, it is recommended to visit a reputable hospital and undergo the procedure under the guidance of a qualified physician. After treatment, patients should maintain clean and dry skin, avoid direct sunlight exposure and consumption of irritating foods, and appropriately supplement with vitamins and water to facilitate skin recovery.
Generally, the principle of using picosecond laser for the treatment of freckles is mainly based on the high energy and precision of the laser. If necessary, it is recommended to visit a reputable hospital and undergo the procedure under the guidance of a qualified physician. A detailed explanation is as follows:
Picosecond laser is an advanced laser technology, with each pulse lasting only picoseconds. This allows more precise targeting of the affected tissue while minimizing damage to surrounding healthy tissue. When used for treating freckles, the picosecond laser can accurately identify melanin granules in the skin. These melanin granules absorb the specific wavelength of laser energy, which helps break them down. Additionally, the treatment can promote skin metabolism, accelerating the removal of pigment particles and facilitating skin repair. The typical reference cost for picosecond laser treatment for freckles is 2000–6000 RMB per session, with visible improvement generally noticeable after 7–15 days. However, possible side effects include skin burns and scarring.
After treatment, patients should maintain clean and dry skin, avoid direct sun exposure, refrain from consuming irritating foods, and appropriately supplement with vitamins and water to aid in skin recovery.
