Dark circles are divided into pigment type, vascular type and mixed type, the general reasons are as follows: pigment type because the eyelid skin is thin, sun exposure is easier to tan, the formation of light brown dark circles; vascular type because the blood vessels around the eyes are dense, after excessive use of the eyes, vascular blood flow slows down, blood stasis, will form dark purple dark circles; mixed type is a combination of both. 1, for pigmentation problems, first do a good job of sun protection. It is recommended to squeeze out a dollar coin-sized amount of sunscreen each time you go out, pat your whole face well and reapply every 3 hours. In addition, you can also use some serums or eye creams with whitening ingredients. Most serums from big brands can be used around the eyes, but please try a small area first and use it when you feel there is no problem, or use eye cream directly. If there is no improvement and you want to do further treatment, you can consider medical cosmetic modalities, such as fractional ruby laser to reduce pigmentation. 2, for vascular problems, it is necessary to pay attention to rest, moderate use of the eyes, hot compresses also have some effect. However, these measures are slow to improve vascular problems and require long-term persistence and good habits. In addition, both topical drugs and skin care products are ineffective for vascular problems, and medical beauty modalities have limited effect and are not recommended for the time being.
