Camouflage: everything you need to know about dark circles under eyes

According to the Federal State Budgetary Institution NMIC TPM [National Medical Research Centre of Therapy and Preventive Medicine] of the Ministry of Health of the Russian Federation, thinning of the fat layer is the most common cause of dark circles. Skin of lower eyelids is separated from orbicularis oculi (a facial muscle situated just beneath the eyelid skin) and blood vessels by thin hypodermis. It gets thinner with age. Sometimes orbicularis oculi and blood vessels become visible even through the thickest skin. The muscle has a dark red colour, the vessels are more cherry-coloured. The colour of under eyes circles depends on what is more visible: vessels or orbicularis oculi [7].
