There is no permanent effect of laser removal of dark circles under the eyes, how long the effect can last is affected by many factors, such as personal constitution, the nature of dark circles under the eyes, and postoperative care, etc. Usually, it can last more than 2 years. Usually it can last for more than 2 years, some people may have dark circles again due to improper care and irregular work and rest. Dark circles are classified into vascular, pigmented and structural types, among which pigmented dark circles are caused by localized pigmentation, which can be improved through laser treatment by breaking up melanin particles and improving localized venous and lymphatic reflux. Laser treatment is less invasive, but it may not be able to get rid of them completely at one time. If the daily cleaning is not in place and the work and rest are not regular, the dark circles are likely to rebound after a few years. Vascularized dark circles are usually found in the lower part of the eyelids. Due to little or no subcutaneous fat in the eyelids, the skin is more translucent and bright and thin, and the orbicularis oculi muscle and the blood vessels contained therein are visible, and they need to be improved by radiofrequency treatment and hydrafacial treatment. Structural dark circles are related to anatomical structures and need to be improved by surgical excision and filling, and laser treatment is less effective. After the dark circles are removed by laser, you need to pay attention to the care around the eyes, often do eye patches, eye masks and steam eye masks, and pay attention to adjusting your state of life, which can delay the reappearance of dark circles.
