Background
Eye skin thickness is very thin, is 1/3 ~ 1/5 of facial skin thickness only, and only sebaceous gland and metamorphosis sweat gland around the eye, and is little to eye skin protection, and eye skin fat content is few simultaneously, lacks elastic fiber and collagen structure, and the nerve fiber and the capillary distribution density around the eye are high, and blood circulation is not smooth etc. lead to the eye dim, and is tired, and then life and rest are irregular, and improper the eye will appear black eye circle, pouch, crow's feet, fat grain scheduling problem easily.
Among them, the dark eye circles are located in the ring shape under the two side orbits, and appear dark black or dark tea, which is a common eye problem. The black eye is classified into a plain black eye, a vascular black eye, a structural black eye and a mixed black eye in which the black eyes are combined at the same time, according to the cause. The reason of the pigmentary black eye is that melanin is locally accumulated around the eyes due to long-term sunlight irradiation, lack of nutrient substances, smoking, aging and the like, and the existence of a large amount of melanin particles is analyzed by detecting the corium layer of the black eye around the eyes; the blood vessel black eye is mainly caused by factors such as insufficient sleep, eye fatigue and the like, the blood flow in the capillary vessel is slow, the blood volume is increased, the oxygen consumption is increased, the hypoxia heme is greatly increased, and the phenomena of blood stasis and edema of the skin around the eyes are caused, and the blood vessel black eye appears after light reflection. At present, most people present mixed black eyes combined by a plurality of black eyes, such as pigmentary combined vascular black eyes, and most of the existing products are directed at the pigmentary black eyes and cannot effectively improve two types of black eyes at the same time.
Based on this, there is a need for an ophthalmic product that can target pigmented and vascular black eyes.
