Retinol, the active form of vitamin A, is a yellow fat-soluble anti-oxidant vitamin that plays an important role in the growth of vision and bones. It belongs to the family of chemical compounds known as retinoids. Retinol is ingested in a precursor form; animal sources (milk and eggs) contain retinyl esters, while plants (carrots, spinach) contain pro-vitamin A carotenoids.
So what does retinol do for you?
Retinol helps to plump the skin. This is very effective when it comes to fighting fine lines on the eye area. Retinol also thickens the epidermis. Now, it's valuable for the eye area because the skin around the eyes is twice as thin as the skin of the face. As a result, it is very sensitive and has a lower ability to build collagen to smooth the skin. Retinol also helps to improve texture and blood circulation. As we already know, dark circles are mainly caused by your capillaries around the eye area. These capillaries sometimes break very easily, allowing blood to flow around the eye area, resulting in red, purple or blue rings under the eyes. These are actually your black circles. Therefore, use creams that also contain vitamin K because vitamin K helps to contract the capillaries.
Here, with retinol, it is helpful to circulate your blood around the eye area so that the blood is not easily pooled in the eyes. Beside, the skin in the eye area is the thinnest, so that they are easily damaged by the sun. Retinol helps rebuild damaged cells from harmful UV rays.
