Closed comedones (whiteheads) are small, skin‑colored bumps caused by clogged pores with oil and dead skin cells, commonly appearing on the forehead and cheeks. They often result from excess sebum, buildup of dead skin, comedogenic skincare or makeup, and sometimes hormonal changes. A safe skincare routine includes using gentle cleansers, applying non‑comedogenic moisturisers, and incorporating salicylic acid or retinoids to help unclog pores and normalise cell turnover. Avoid picking or squeezing the bumps, as this can cause scarring or infection. Improvement usually takes several weeks of consistent care. If the bumps persist, worsen, or affect your confidence, consult a dermatologist for tailored treatment, which may include professional procedures like chemical peels, comedone extraction, or prescription medications.
