The link between stress and skin goes back to the hypothalamic-pituitary-adrenal axis in the brain, which regulates the body's response to stress, Dr. Evan Rieder, a board-certified dermatologist ...
The skin weighs an average of 4 kg (8.8 lb), covers an area of about 2 m 2 (22 sq ft), and is made of three distinct layers: the epidermis, dermis, and subcutaneous tissue. [1] The two main types of human skin are glabrous skin, the nonhairy skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin. [16]
Inflammation, on the other hand, describes just the body's immunovascular response, regardless of cause. But, because the two are often correlated, words ending in the suffix -itis (which means inflammation) are sometimes informally described as referring to infection: for example, the word urethritis strictly means only "urethral inflammation ...
The two main types of human skin are: glabrous skin, the hairless skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin. [3] Within the latter type, the hairs occur in structures called pilosebaceous units, each with hair follicle, sebaceous gland, and associated arrector pili muscle. [4]
You may have been warned about this before, and perhaps have even seen the results of stress on your skin when you have a big presentation at work, or durin
The area of skin involved can vary from small to covering the entire body. [1] [2] Dermatitis is also called eczema but the same term is often used for the most common type of skin inflammation, atopic dermatitis. [7] The exact cause of the condition is often unclear. [2] Cases may involve a combination of allergy and poor venous return. [1]
Oxidative stress is connected to cancer, diabetes, heart disease, and some skin diseases, including dermatitis. “Antioxidants help the skin respond to outside irritants or injuries,” Dr ...
An alternative explanation is an increase in sebum production feeding an increase in the Malassezia population that instigates inflammation; the inflammation then causes cellular changes that damage the skin barrier. This barrier disruption then encourages additional Malassezia growth and inflammation and again worsened skin barrier function. [12]
