Non-inflammatory acne, including blackheads and whiteheads, is primarily caused by the buildup of dead skin cells and oil. In the sebaceous glands of the skin, sebum is produced to help keep the skin moisturized. When this oil combines with dead skin cells, it can clog the hair follicles. If the clogged pore remains closed, it results in a whitehead; if it is open to the air, oxidation occurs, causing the surface to darken, which is known as a blackhead. This process is different from inflammatory acne, which typically involves bacteria and immune responses that cause redness and swelling. Factors such as excess sweat production, allergic reactions, or infections are not directly responsible for non-inflammatory forms of acne. Instead, maintaining a proper balance of exfoliation and oil production is essential in preventing these types of acne.
