A white pimple or whitehead typically indicates a clogged pore filled with sebum (oil), dead skin cells, and possibly bacteria. It is a common type of acne and usually occurs when the hair follicles become blocked. Whiteheads are generally considered non-inflammatory and can be treated with proper skincare such as gentle cleansing, exfoliation, and using products containing salicylic acid or benzoyl peroxide. If the issue persists or worsens, it’s advisable to consult a dermatologist for further evaluation and treatment.
