The eye contour is a very sensitive and delicate area. Skin is thinner and hence more exposed to external aggressions. Because of a low microcirculation, blood vessels are more visible and give a bluish or brown colour to the skin. Moreover, cell exchanges are less important and puff appear under the eye. Various factors as stres, sun exposure or genetic predispositions can be the cause of dark circle, periocular hyperpigmentation and puffiness. For those reasons, it is imperative to protect the eye contour to make it less sensitive and vulnerable to external aggressions.
