Some Dermatology Terms to Be Aware Of
(in no particular order)
Acne
Acne is a common skin problem that shows up as outbreaks of bumps, papules and/or pustules often called pimples or zits. Acne lesions usually appear on the face, neck, back, chest, and shoulders. Although most people associate the disorder with teenagers, acne can emerge at any age until menopause, especially during times of hormonal flux.
Acne occurs when excess sebum created by the sebaceous glands, builds up beneath the skin within a hair follicle (“pore”). This creates a small bump called a “comedo”. A comedo may be referred to as a “blackhead” if the sebum has darkened upon exposure to air. The sebum can become infected with bacteria (p. acnes) which causes the lesion to become red and inflamed. The severity of acne is determined by the extent of the lesions and the degree of inflammation.
Acne can be a source of emotional distress and severe acne, particularly “cystic” or “nodulocystic” acne can lead to permanent scars.
Treatment recommendations are based on the severity of the acne and other variables, and may include benzoyl peroxide, topical retinoids (Differin, Epiduo, Retin A Micro, Tazorac, tretinoin, and Ziana), dapsone (Aczone), topical antibiotics (Duac, Clindagel), oral antibiotics, birth control pills (Yaz, Ortho Tri-Cyclen), isotretinoin (Accutane, Sotret), and various laser and light sources, such as photodynamic therapy (PDT).
Blister
An enclosed collection (bubble) of fluid within or beneath the epidermis.
Cellulitis
An infection of the skin, usually by bacteria (staph and strep).
Chronic
Long-lasting. The opposite of acute.
Comedo (Blackheads and Whiteheads)
A dilated hair follicle and sebaceous gland filled with sebum and bacteria. A comedo may be “open” in which the sebum is exposed to the air causing the sebum inside to turn dark or black. This is referred to as a “blackhead.” A comedo may be “closed” in which the sebum inside remains white. This is referred to as a “whitehead.”
Dermatitis
A general term used to describe inflamed skin. There can be many causes of dermatitis, such as an allergic reaction or atopic dermatitis. Dermatitis can be short-term (“acute”) or long-term (“chronic”). Acute dermatitis causes the skin to appear red, blistered or swollen. Chronic dermatitis causes the skin to appear thickened, rough, and darker than the surrounding skin.
Epidermis
The top layer of skin that lies above the dermis. Epidermis is composed primarily of a type of squamous cell called a keratinocyte. Cells at the base of the epidermis (basal cells) generate keratinocytes that grow to the surface. The epidermis replaces itself every 12-14 days. There are no blood vessels in the epidermis so a cut or scrap of the epidermis does not bleed
Hair follicle
The part of the dermis from which hair grows. Sebaceous glands are often connected to hair follicles.
Immune system
A complex network of specialized cells and organs that work together to defend the body against “foreign” invaders such as bacteria and viruses. In some conditions, the immune system may not function properly and may even work against the body. This leads to “autoimmune” diseases, such as arthritis and lupus.
Ringworm
A fungal skin infection caused by a dermatophyte. Similar fungi may cause athlete’s foot or jock itch. Ringworm is not caused by a worm.
Sunscreen
This lotion, cream, or spray is the single most important anti-aging weapon you can buy. Sunscreen uses chemicals or physical blockers to prevent a certain percentage of ultraviolet light from getting to the skin and attacking and damaging the skin cells.
In order to guard against both UVA and UVB, you must wear a sunscreen labeled broad spectrum. Most broad-spectrum sunscreens contain the powerful UVA blocker avobenzone. However, since this ingredient breaks down after exposure to sunlight, some companies are stabilizing it with additives like Helioplex, which dramatically prolong the life span of the sunscreen. The latest UVA blocker to hit the United States is Mexoryl, which remains stable and effective even after four hours of sunlight exposure.
Topical
Something that is applied to the skin, such as an ointment or cream. A medication to be rubbed over a rash may be referred to as a topical medication.
