Acneiform eruption refers to a group of dermatoses including acne vulgaris, rosacea, folliculitis, and perioral dermatitis. Restated, acneiform eruptions are follicular eruptions characterized by papules and pustules resembling acne. The term "acneiform", literally, refers to an appearance similar to acne.
The terminology used in this field can be complex, and occasionally contradictory. Some sources consider acne vulgaris part of the differential diagnosis for an acneiform eruption. Other sources classified acne vulgaris under acneiform eruption. MeSH explicitly excludes perioral dermatitis from the category of "acneiform eruptions", though it does group acneiform eruptions and perioral dermatitis together under "facial dermatoses".
Acne vulgaris (or simply acne) is a common human skin disease, characterized by areas of skin with seborrhea (scaly red skin), comedones (blackheads and whiteheads), papules (pinheads), nodules (large papules), pimples, and possibly scarring. Acne affects mostly skin with the densest population of sebaceous follicles; these areas include the face, the upper part of the chest, and the back. Severe acne is inflammatory, but acne can also manifest in noninflammatory forms. The lesions are caused by changes in pilosebaceous units, skin structures consisting of a hair follicle and its associated sebaceous gland, changes that require androgen stimulation.
Acne occurs most commonly during adolescence, affecting an estimated 70-90% of teenagers. In adolescence, acne is usually caused by an increase in testosterone, which occurs during puberty, regardless of sex. For most people, acne diminishes over time and tends to disappear — or at the very least decreases — by age 25. There is, however, no way to predict how long it will take to disappear entirely, and some individuals will carry this condition well into their thirties, forties, and beyond.
ATC code D10 Anti-acne preparations is a therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System, a system of alphanumeric codes developed by the WHO for the classification of drugs and other medical products. Subgroup D10 is part of the anatomical group DermatologicalsD .
Codes for veterinary use (ATCvet codes) can be created by placing the letter Q in front of the human ATC code: QD10...
Rubbing alcohol, USP / Surgical spirit, B.P. is a liquid prepared and used primarily for topical application. It is prepared from a special denatured alcohol solution and contains approximately 70 percent by volume of pure, concentrated ethanol (ethyl alcohol) or isopropyl alcohol (isopropanol). Individual manufacturers can use their own "formulation standards" in which the ethanol content usually ranges from 70-99% v/v. In Ireland and the UK, the equivalent skin preparation is surgical spirit, which is always an ethyl alcohol-isopropyl alcohol mixture. It is colorless. The melting point is -89 °C. The boiling point is 82.5 °C.
The term "rubbing alcohol" has become a general non-specific term for either isopropyl alcohol (isopropanol) or ethyl alcohol (ethanol) rubbing-alcohol products.
Cosmetics (colloquially known as makeup or make-up) are care substances used to enhance the appearance or odor of the human body. They are generally mixtures of chemical compounds, some being derived from natural sources, many being synthetic.
In the U.S., the Food and Drug Administration (FDA), which regulates cosmetics, defines cosmetics as "intended to be applied to the human body for cleansing, beautifying, promoting attractiveness, or altering the appearance without affecting the body's structure or functions." This broad definition also includes any material intended for use as a component of a cosmetic product. The FDA specifically excludes soap from this category.
