The eye contour is a sensitive area of the face that requires specific care to address all the issues it may encounter (dark circles, bags, fine lines...). Unlike traditional facial care, eye contour treatments have undergone ophthalmological tests, as they are likely to migrate by capillarity and come into contact with the eye. Moreover, they are formulated at a neutral pH to adapt to this area. The pH of the eye contour is about 7, while it is generally between 4.7 and 5.7 on the rest of the face.
The primary function of the skin around the eyes is tohydrate this delicate area. Indeed, the eyelids are very poor in sebaceous glands, which means that the hydrolipidic film in this area is virtually nonexistent. Therefore, the eye contour is barely protected from external aggressions and dehydration. To compensate for this lack, it is beneficial to apply a cream containing both hydrating/humectant active ingredients, such ashyaluronic acid or aloe vera gel, and film-forming agents such as oils or vegetable butters.
Boasting a strong hygroscopic capacity, moisturizing molecules retain water within the skin, thereby limiting insensible water loss (IWL). Film-forming agents, on the other hand, recreate an equivalent of the hydrolipidic film to protect the skin from pollution, UV rays, and dehydration. It's also worth noting that hydrating the eye contour can prevent the appearance of dehydration fine lines at the corner of the eye.
Some eye contour treatments also contain ingredients that protect the skin from the dangers of the sun. Indeed, let's remember that this area is very thin and therefore easily allows UV rays to penetrate, which are responsible for the excessive generation of free radicals. These species cause several damages to the skin and DNA, and are among other things responsible for the acceleration of skin aging and pigmentation disorders. To protect oneself, it is good to rely on eye contour treatments with a sun protection factor (SPF) or rich in antioxidants, such as vitamin C or polyphenols. These molecules are capable of neutralizing free radicals by donating an electron.
