What is Atopic Dermatitis?
Atopic dermatitis is also known as eczema. It is a skin disorder mainly caused due to a family history of allergic reactions. The main triggers of atopic dermatitis are changes in genes, problems with the immune system, and exposure to certain things in the environment. Atopic dermatitis is not contagious, so it does not spread from person to person. The common symptoms of atopic dermatitis include itchiness, red, dry patches of skin, rashes that may ooze clear fluids or bleed while scratching, thickening and hardening of the skin, asthma, other skin diseases like ichthyosis, depression, anxiety, and sleep loss. The commonly affected areas in the body in this condition include the hands, neck, elbows, and knees, the skin around the eyes, ankles, and feet.

Atopic dermatitis can be diagnosed through medical history, examining the skin through biopsies, and other tests to check for other causes of rash. Furthermore, treatment options for atopic dermatitis include emollients, topical corticosteroids, topical pimecrolimus, antihistamines, bandages to allow the body to heal underneath, and complementary remedies (herbal remedies).
What is Seborrheic Dermatitis?
Seborrheic dermatitis is a common skin disease that mainly affects the scalp. Usually, it causes scaly patches, inflamed skin, and dandruff. Seborrheic dermatitis generally affects oily areas of the body like the face, sides of the nose, eyebrows, ears, eyelids, and chest. Though this condition is irritating, it is not contagious. This disease can be mainly caused due to yeast called Malassezia, excess oil in the skin, or a problem in the immune system. The symptoms of this condition are dandruff on the scalp, hair, eyebrows, beard or mustache, patches of greasy skin covered with flaky white or yellow scales on the scalp, face, sides of the nose, eyebrows, ears, eyelids, chest, armpits, groin or breast, darker rashes people with brown or black skin and redder rashes those with white skin, ring-shaped rash, and itchiness.
