The skin—the body’s largest organ naturally excretes oil, so using it to replenish, cleanse and hydrate seems fitting. In fact, in some countries, like Japan, using oil-based skin-care products is the preferred way of caring for the skin. As we age, moisture levels in the skin drop, causing it to become dry and dehydrated, in turn making fine lines and wrinkles more noticeable. You may be surprised to learn that a large majority of skin-care products boast an oil agent as a main ingredient.

But how does oil work with skin? Because oil is an emollient, it fills in the spaces between the cells in the upper levels of the skin. By replacing these essential lipids, products that are oil-based smooth and lubricate rough skin. Because of their chemical structure, the skin more easily absorbs oils than water-based moisturizers.

Just make sure you choose the right ones. Some types of oils—like mineral and coconut oils—can potentially clog your pores and may even be detrimental to the health of your skin. But others like the following provide important benefits.

Jojoba Oil: the skin strengthener. Similar in structure to that of natural sebum, jojoba oil can help reduce the production of oil while strengthening the epidermis.

Tea Tree Oil: antifungal and antibacterial. Tea tree oil has been used for centuries to heal the skin. In addition, it carries oxygen into the hair follicles, reducing and killing the bacteria that lead to pimples.

Almond Oil: the skin soother. Used for centuries for its ability to nourish, almond oil is ideal for soothing sensitive skin.

Wheat Germ Oil: the acne fighter. A rich source of omega-3 and omega-6 essential fatty acids, wheat germ oil is effective in treating acne and blemishes, and provides antioxidant protective properties.
