Keratosis pilaris is a common, harmless skin condition caused by an abnormal maturation of keratin cells in the hair follicles. Keratosis pilaris usually develops during childhood and can occur in both boys and girls.
Symptoms
- Small bumps: Usually on the upper arms, sometimes also on thighs, cheeks, or buttocks.
- Roughness: The skin may feel rough, similar to sandpaper.
- Itching: The skin may sometimes be itchy or irritated.
- Dryness: Especially in the winter months, the skin may feel drier and rougher.
Causes
- Genetic factors: Keratosis pilaris is often hereditary.
- Keratin buildup: The condition is caused by an excessive production of keratin around the pores, a protein that protects the skin from harmful substances and infections.
Diagnosis
- Diagnosis is usually based on the appearance of the skin. Sometimes, a dermatologist may take a skin sample to rule out other conditions.
Treatment
- Creams with urea or lactic acid: These help remove dead skin cells.
- Moisturizing creams: Regular use can reduce dry skin.
Self-care Tips
- Mild skincare products: Use soap-free cleansers and moisturizing creams.
- Short warm showers: Avoid long hot showers.
- Gentle skin scrubs: These can help remove dead skin cells.
