The main reasons for breaking out badly include excess oil production, clogged hair follicles by dead skin cells and oil, inflammation caused by bacteria, and hormonal changes. Additional common causes are stress (which increases oil production and inflammation), the use of certain skincare or makeup products that clog pores, insufficient sleep, smoking, and physical contact with the skin transferring bacteria. Diet may play a role in some cases, particularly foods high in refined sugars or dairy, although this is still controversial. Acne can also be worsened by overusing acne treatments that irritate the skin and cause excess oil production in response. Breakouts tend to occur where there are many oil glands such as the face, chest, upper back, and shoulders. Hormonal fluctuations during puberty, menstruation, pregnancy, or conditions like polycystic ovarian syndrome are strong contributors to acne severity. For adult acne, stress and genetics also play significant roles that can cause breakouts even later in life. In summary, breakouts happen when pores become clogged with oil, dead skin cells, and sometimes bacteria, causing inflammation. Lifestyle factors, products used, and hormonal changes can trigger or worsen acne through multiple pathways. Managing stress, using non- comedogenic skincare, and proper hygiene can help reduce flare-ups.
