The most superficial layer of the skin is the epidermis which is attached to the deeper dermis. The skin is made of multiple layers of cells and tissues, which are held to underlying structures by connective tissue ( Figure 5.1.1).

The skin and its accessory structures make up the integumentary system, which provides the body with overall protection.

'Triterpenes, which are present in many plant oils and in particular olive oil, aid in many biological reactions like those necessary for wound healing: cell migration, cell proliferation, and collagen deposition,' she says. 'With the added benefits of antioxidants and hydrating squalane, it moisturizes the delicate skin in the eye area, plus nourishes eyelashes the same way conditioner works on the hair.' While olive oil can lift off and move oil-soluble residues (like makeup and sebum) around the skin, it does not necessarily remove the makeup, and both the olive oil and broken down makeup should be wiped off with a cleanser. Lifts makeup: 'Olive oil is great for breaking down waxy substances like waterproof mascara and eyeliner,' explains Dr.'These can aid with decreasing oxidative stress on the skin (which could lead to accelerated skin aging).' Prevents premature aging: 'Olive oil is rich in vitamins A, D, K, and E, as well as squalane,' says Dr.'This means protection against premature aging as well as signs of irritation or redness.' Protects against environmental damage: 'Olive oil's antioxidant properties protect skin cells against environmental damage and inflammation,' notes Ng.Prevents water loss: 'Olive oil’s main benefit is to moisturize the skin by reducing water loss,' says cosmetic chemist, Ee Ting Ng. 'This moisturization increases the water content of the skin, improving its health and appearance.'.
