👉 Acne fluid, also known as sebum or sebum exudate, is a mixture of lipids, water, and other substances produced by the sebaceous glands in the skin. When these glands become clogged with dead skin cells and excess oil, it can lead to the formation of comedones (blackheads and whiteheads). When an acne lesion becomes inflamed, bacteria can invade, causing irritation and the release of inflammatory fluids. This fluid, rich in lipids and proteins, can contribute to the redness, swelling, and pus formation characteristic of acne lesions. Understanding acne fluid helps in grasping the complex interplay between hormonal changes, bacterial activity, and skin cell turnover that underlies acne development.
