FAQs
What are some common skin conditions?
Some of the most common skin conditions include acne, eczema, psoriasis, rosacea, fungal infections, hives, cold sores and contact dermatitis. Skin conditions can be caused by allergens, irritants, immune system responses, viruses, bacteria or fungi.
What causes red, itchy skin?
Red, itchy skin can be caused by many conditions like eczema, allergic reactions, insect bites, fungal infections, sunburn, and skin conditions like psoriasis. Dry skin can also become red and itchy when irritated. Identifying the exact cause is key to treatment.
How can I tell if a skin rash is contagious?
Contagious skin conditions like impetigo, ringworm and scabies often spread through direct skin contact or shared surfaces. Rashes that are weeping, oozing or crusting have a higher risk of infecting others. Non-contagious rashes like eczema, psoriasis and hives do not spread between people.
