What to expect from curettage and cautery for dermatosis papulosa nigra

Dermatosis papulosa nigra causes small, dark, raised bumps, often on the face or neck. The clinician confirms the diagnosis before treatment because other pigmented lesions can look similar. Local anaesthetic reduces sensation. Curettage gently lifts or scrapes away a selected bump, while cautery treats the small surface left behind and helps control bleeding. Several bumps may be treated in one visit, depending on their size, number and location.

Follow the clinic's instructions for cleaning and covering each spot. Avoid rubbing, scratching, exfoliating products and makeup on open areas until the surface has closed as advised. Protect healing skin from sunlight with the method your clinician recommends, since pigment changes can follow inflammation, especially in darker skin tones. Do not use home acids or attempt to remove new bumps yourself. A follow-up can check healing and discuss further treatment if some bumps remain.

Seek advice if bleeding does not stop with firm, gentle pressure, or if redness spreads, pain worsens, swelling increases or discharge appears. Fever or a rapidly changing treated area needs prompt clinical review. New or changing pigmented bumps should also be assessed rather than assumed to be dermatosis papulosa nigra.

Ask how your skin tone may affect temporary or longer-lasting colour change, whether all visible bumps can be treated at once, and which products should be paused. Clarify scar care, sun protection and the date of review.
