Overview
Skin conditions are among the most common health issues. While many are harmless and manageable, some require medical attention. Learning to identify common conditions helps you take appropriate action.
Common skin conditions
Eczema (atopic dermatitis)
Causes dry, itchy, inflamed patches. Common on hands, feet, inner elbows, and behind knees. Often runs in families and is linked to allergies and asthma.
Psoriasis
Autoimmune condition causing thick, red, scaly patches. Most common on elbows, knees, scalp, and lower back. Not contagious.
Acne
Caused by clogged pores, bacteria, and hormones. Affects face, back, and chest. Most common in teens but can occur at any age.
Contact dermatitis
Rash caused by contact with an irritant or allergen. Common triggers include soaps, cosmetics, metals (nickel), and plants (poison ivy).
Hives (urticaria)
Raised, itchy welts triggered by allergies, stress, infections, or temperature changes. Usually resolves within hours to days.
Self-care tips
- Moisturize regularly: especially after bathing
- Use gentle, fragrance-free products
- Avoid known triggers: keep a diary of flare-ups
- Don't scratch: use cool compresses for itch relief
- Protect from sun: use SPF 30+ sunscreen daily
- Stay hydrated: drink enough water
- Manage stress: stress worsens many skin conditions
When to seek care
See a dermatologist if skin issues are spreading or worsening, home treatments aren't working, a mole changes shape or color, you have a wound that won't heal, or skin symptoms are accompanied by fever.
Healthy skin reflects overall health. Establish a consistent skincare routine and protect your skin daily.
