Sebum
Did you know that your skin has its own natural moisturizer? It's called sebum, and it's produced by the skin's sebaceous glands. Although it is often associated with acne and oily skin, sebum actually plays a vital role in maintaining healthy skin. One of the key functions of sebum is to keep the skin hydrated by forming a protective layer on the skin's surface, which helps prevent water loss. In addition to its moisturizing properties, sebum also helps protect the skin from environmental damage. However, excessive sebum production can lead to oily skin and acne, so it is important to maintain a healthy sebum balance through proper skin care, a healthy diet, and other lifestyle factors.
