Yes, skin contains cholesterol. Cholesterol is a crucial component of the skin's outermost layer, the stratum corneum, which acts as a barrier to prevent water loss and protect the body from external threats.
The stratum corneum contains a hydrophobic lipid matrix composed primarily of ceramides, cholesterol, and free fatty acids. Cholesterol plays a vital role in maintaining the integrity of this barrier by contributing to its structural stability and preventing water evaporation.
While cholesterol is essential for healthy skin, elevated cholesterol levels can lead to skin conditions like xanthelasma, which are yellowish, cholesterol-rich deposits that appear on the eyelids.
