What should you know about chicken pox black spots?

A dark mark can remain after a bump heals, especially after scratching or picking. A crust may look dark while the surface is repairing, whereas a flat brown or grey mark may be post-inflammatory colour change. Acne, folliculitis, razor bumps, rosacea, and perioral dermatitis can all create bumps that later leave marks. The appearance alone cannot identify the cause. Note whether spots are flat or raised, whether new lesions continue to appear, and whether there is pain, itch, crusting, or discharge.

Cleanse gently, leave scabs in place, and use a bland moisturiser if the skin is dry. Avoid squeezing, scratching, strong acids, and unlabelled lightening creams. Protect exposed skin from sunlight with shade, clothing, and suitable sunscreen, because light can make some post-inflammatory marks linger. If the spots began after shaving, pause close shaving and reduce friction. A clinician can advise whether a treatment for the underlying acne-like condition is appropriate; LED light therapy should be discussed rather than started as a substitute for diagnosis.

Seek prompt care if a spot is rapidly enlarging, very painful, hot, bleeding, ulcerated, or surrounded by spreading swelling. Fever, facial swelling, eye involvement, or feeling acutely unwell raises the need for urgent assessment. Arrange a routine dermatology review for marks that persist, recur in the same area, or follow a rash that has not been identified. Bring photographs showing how the spots changed.

Ask whether the marks are scars, crusts, or post-inflammatory colour change; whether acne, folliculitis, razor bumps, rosacea, or perioral dermatitis fits the pattern; and which treatment is safe for your skin. Ask what warning changes need review.
