Maskne (pronounced mask-nee and sometimes spelled mask-ne or mascne) is a portmanteau of "mask" and "acne." The term appeared in use during the COVID-19 pandemic in 2020 to refer to acne and other rashes of the face that occur in association with mask wearing. [1] The findings are observational only and related to pressure, occlusion and friction. It is likely that several are perioral dermatitis, rosacea, seborrheic dermatitis, folliculitis, irritant contact dermatitis or allergic contact dermatitis, and acne mechanica. [2] [3] [4] In one article, maskne is observed to be caused by increase of humidity in the occluded area and sebum being secreted, increasing the amount of squalene on the skin. This, along with excess sweating lead to the swelling of epidermal keratinocytes, causing acute obstruction and acne aggravation. [5] The hot and humid environment in which maskne is induced is also apparent with tropical acne. [6] [7] The best treatment for maskne is to avoid wearing a mask.
Following the CDC's recommendations for face coverings, [8] essential workers and those following government mask mandates reported experiencing increasing outbreaks of acne. [9] As early as March 2020, reports were showing that at least 83% of health care workers in Hubei, China, suffered from skin irritation on the face. [10] In June 2020, the printed use of the word "maskne" appeared in both Italian [11] and English. [9] In a June 2020 New York Times article, written by Courtney Rubin, dermatologists explain that the most common kind of maskne is acne mechanica. [9] The term "maskne" was also used by BBC News in July 2020. [12] In September 2020, the National Society for Cutaneous Medicine published the article "Maskne: Exacerbation or Eruption of Acne During the COVID-19 Pandemic". [13] In July 2021, an article written by Amy Sheehan, Tessa Mapstone, and Sheridan Stewart on ABC News (Australia) reported on the increase of "maskne" from mandatory mask rules. [14]
Acne, also known as acne vulgaris, is a long-term skin condition that occurs when dead skin cells and oil from the skin clog hair follicles. Typical features of the condition include blackheads or whiteheads, pimples, oily skin, and possible scarring. It primarily affects skin with a relatively high number of oil glands, including the face, upper part of the chest, and back. The resulting appearance can lead to anxiety, reduced self-esteem, and, in extreme cases, depression or thoughts of suicide.
A sebaceous gland is a microscopic exocrine gland in the skin that opens into a hair follicle to secrete an oily or waxy matter, called sebum, which lubricates the hair and skin of mammals. In humans, sebaceous glands occur in the greatest number on the face and scalp, but also on all parts of the skin except the palms of the hands and soles of the feet. In the eyelids, meibomian glands, also called tarsal glands, are a type of sebaceous gland that secrete a special type of sebum into tears. Surrounding the female nipple, areolar glands are specialized sebaceous glands for lubricating the nipple. Fordyce spots are benign, visible, sebaceous glands found usually on the lips, gums and inner cheeks, and genitals.
Chilblains, also known as pernio, is a medical condition in which damage occurs to capillary beds in the skin, most often in the hands or feet, when blood perfuses into the nearby tissue resulting in redness, itching, inflammation, and possibly blisters. It occurs most frequently when predisposed individuals, predominantly women, are exposed to cold and humidity. Ulcerated chilblains are referred to as kibes. Temperature-related chilblains can be prevented by keeping the feet and hands warm in cold weather and avoiding exposing these areas to extreme temperature changes. Once the diagnosis of chilblains is made, first-line treatment includes avoiding cold, damp environments and wearing gloves and warm socks.
Rosacea is a long-term skin condition that typically affects the face. It results in redness, pimples, swelling, and small and superficial dilated blood vessels. Often, the nose, cheeks, forehead, and chin are most involved. A red, enlarged nose may occur in severe disease, a condition known as rhinophyma.
Hyperpigmentation is the darkening of an area of skin or nails caused by increased melanin.
Keratosis pilaris is a common, autosomal-dominant, genetic condition of the skin's hair follicles characterized by the appearance of possibly itchy, small, gooseflesh-like bumps, with varying degrees of reddening or inflammation. It most often appears on the outer sides of the upper arms, thighs, face, back, and buttocks; KP can also occur on the hands, and tops of legs, sides, or any body part except glabrous (hairless) skin. Often the lesions can appear on the face, which may be mistaken for acne or folliculitis.
Nummular dermatitis is one of the many forms of dermatitis. it is characterized by round or oval-shaped itchy lesions. The name comes from the Latin word "nummus," which means "coin."
The management of hair loss, also known as alopecia or baldness, includes prevention and treatment of hair loss, and regrowth of hair.
Cutis verticis gyrata is a medical condition usually associated with thickening of the scalp. The condition is identified by excessive thickening of the soft tissues of the scalp and characterized by ridges and furrows, which give the scalp a cerebriform appearance. Clinically, the ridges are hard and cannot be flattened on applying pressure. Patients show visible folds, ridges or creases on the surface of the top of the scalp. The number of folds can vary from two to roughly ten and are typically soft and spongy. The condition typically affects the central and rear regions of the scalp, but sometimes can involve the entire scalp.
A Dennie–Morgan fold, also known as a Dennie–Morgan line or an infraorbital fold, is a fold or line in the skin below the lower eyelid. It can simply be an ethnic/genetic trait, but was found in one study to occur in 25% of patients with atopic dermatitis. The presence of Dennie–Morgan folds can be used as a diagnostic marker for allergy with a sensitivity of 78% and specificity of 76% according to one study.
Acne conglobata is a highly inflammatory disease presenting with comedones, nodules, abscesses, and draining sinus tracts.
Acne mechanica is an acneiform eruption that has been observed after repetitive physical trauma to the skin such as rubbing, occurring from clothing or sports equipment. In addition to those mechanisms, the skin not getting enough exposure to air also contributes to the formation of acne mechanica. It is often mistaken as a rash that forms on sweaty skin that is constantly being rubbed, but in reality, it is a breakout of acne mechanica. The term "acne" itself describes the occurrence in which hair follicles in the skin get clogged by oil, dead skin cells, dirt and bacteria, or cosmetic products and create a pimple. Pimples can vary in type, size, and shape, but the sole basis of them occurring is the same - the oil gland in the pore becomes clogged and sometimes infected, which creates pus in order to fight the infection and subsequently causes the development of swollen, red lesions on the skin.
Pilomatricoma, is a benign skin tumor derived from the hair matrix. These neoplasms are relatively uncommon and typically occur on the scalp, face, and upper extremities. Clinically, pilomatricomas present as a subcutaneous nodule or cyst with unremarkable overlying epidermis that can range in size from 0.5-3.0 cm, but the largest reported case was 24 cm.
Abietic acid dermatitis is a contact dermatitis often seen in association with musical instruments.
Sodium hypochlorite washes are skin cleansers formulated with sodium hypochlorite (NaOCl) and surfactants. These cleansing liquids or gels are lathered onto wet skin and rinsed off. They are recommended for inflammatory skin conditions, microbial driven skin disorders and body odor.
Dermatoses induced by Personal Protective Equipment are skin lesions that occur due to the use of personal protective equipment (PPE). Personal Protective Equipment such as masks, face shields, googles, gloves and gowns can cause abrasion in the skin and retain moisture in body parts, particularly the face. During the COVID-19 pandemic, healthcare workers and general public need to use personal protective equipment, sometimes for extended duration, which may result in skin problems due to friction, pressure, long-term sealing and moisture retention.
Cutaneous manifestations of COVID-19 are characteristic signs or symptoms of the Coronavirus disease 2019 that occur in the skin. The American Academy of Dermatology reports that skin lesions such as morbilliform, pernio, urticaria, macular erythema, vesicular purpura, papulosquamous purpura and retiform purpura are seen in people with COVID-19. Pernio-like lesions were more common in mild disease while retiform purpura was seen only in critically ill patients. The major dermatologic patterns identified in individuals with COVID-19 are urticarial rash, confluent erythematous/morbilliform rash, papulovesicular exanthem, chilbain-like acral pattern, livedo reticularis and purpuric “vasculitic” pattern. Chilblains and Multisystem inflammatory syndrome in children are also cutaneous manifestations of COVID-19.
Topical glucocorticoids are the topical forms of glucocorticoids. Topical glucocorticoids are used in the treatment of many skin conditions. They provide anti-inflammatory, antimitotic, and immune-system suppressing actions through various mechanisms.
Abirritants, also known as anti-itch drugs are medications used for relieving or preventing itching (pruritus) around the body.
