What should you know about small scaly bumps on skin?

Scale with itch and a defined expanding edge can occur with ringworm. Thicker, sharply outlined plaques may fit psoriasis, while greasy scale around the scalp, eyebrows, ears, or nose can occur with seborrheic dermatitis. Fine scale over lighter or darker patches on the trunk can be seen with tinea versicolor. Irritation, allergy, and simple dryness can also produce rough bumps.

Scaly skin is a symptom shared by different conditions, so the symptom alone does not identify its cause. The body site, color, border, itch, and whether others have similar symptoms matter. Related overviews include [Scaly Skin](/symptoms/skin-scaling/), [Psoriasis](/conditions/psoriasis/), [Ringworm](/conditions/ringworm/), [Seborrheic Dermatitis](/conditions/seborrheic-dermatitis/), and [Tinea Versicolor](/conditions/tinea-versicolor/).

Use a gentle cleanser, lukewarm water, and a fragrance-free moisturizer; [Emollient Therapy](/treatments/medical-dermatology/emollient-therapy/) can support the skin barrier. Avoid picking, harsh scrubs, and sharing towels. Do not use a steroid cream alone on a spreading ring-shaped rash because it can change the appearance of a fungal infection. A clinician can decide whether [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/) or another approach fits.

Arrange an appointment if the bumps spread, persist despite gentle care, crack, ooze, or interfere with sleep. Seek prompt attention for painful warmth, pus, rapidly increasing redness, facial or eye involvement, or fever. Extensive or recurring psoriasis-like symptoms may need a structured plan, which can include [Narrowband UVB Phototherapy](/treatments/medical-dermatology/narrowband-uvb-phototherapy/) when appropriate.

Ask whether the pattern suggests fungus, psoriasis, dermatitis, or dryness; whether a skin scraping is needed; which products to stop; and how long to try the recommended treatment before review.
