Coconut oil is all the rage, with uses ranging from hair conditioning to cooking. But some swear by it as a natural acne treatment. To use coconut oil as an acne treatment, you can include it as part of a healthy diet. The fatty acids like lauric acid and caprylic acid are metabolized into antibacterial agents in the body. Or, you can apply a very small amount and rub directly onto your skin after cleansing for an extra hydrating boost.

A major mechanism of acne-related skin inflammation is mediated by C. acnes's ability to bind and activate a class of immune system receptors known as toll-like receptors (TLRs), especially TLR2 and TLR4. Activation of TLR2 and TLR4 by C. acnes leads to increased secretion of IL-1α, IL-8, and TNF-α. Release of these inflammatory signals attracts various immune cells to the hair follicle including neutrophils, macrophages, and Th1 cells. IL-1α stimulates increased skin cell activity and reproduction, which in turn fuels comedo development. Furthermore, sebaceous gland cells produce more antimicrobial peptides, such as HBD1 and HBD2, in response to binding of TLR2 and TLR4.
Pimples are raised red spots with a white center that develop when blocked hair follicles become inflamed or infected with bacteria. Blockages and inflammation that develop deep inside hair follicles produce cystlike lumps beneath the surface of your skin. Other pores in your skin, which are the openings of the sweat glands, aren't usually involved in acne.
