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 lack of confidence, anxiety, reduced self-esteem, and, in extreme cases, depression or thoughts of suicide.
Waxing is the process of hair removal from the root by using a covering of a sticky substance, such as wax, to adhere to body hair, and then removing this covering and pulling out the hair from the follicle. New hair will not grow back in the previously waxed area for four to six weeks, although some people will start to see regrowth in only a week due to some of their hair being on a different human hair growth cycle. Almost any area of the body can be waxed, including eyebrows, face, pubic hair, legs, arms, back, abdomen, chest, knuckles, and feet. There are many types of waxing suitable for removing unwanted hair.
A cannula is a tube that can be inserted into the body, often for the delivery or removal of fluid or for the gathering of samples. In simple terms, a cannula can surround the inner or outer surfaces of a trocar needle thus extending the effective needle length by at least half the length of the original needle. Its size mainly ranges from 14 to 26 gauge. Different-sized cannula have different colours as coded.
Tretinoin, also known as all-trans retinoic acid (ATRA), is a medication used for the treatment of acne and acute promyelocytic leukemia. For acne, it is applied to the skin as a cream, gel or ointment. For acute promyelocytic leukemia, it is effective only when the RARA-PML fusion mutation is present and is taken by mouth for up to three months. Topical tretinoin is also the most extensively investigated retinoid therapy for photoaging.
A wrinkle, also known as a rhytid, is a fold, ridge or crease in an otherwise smooth surface, such as on skin or fabric. Skin wrinkles typically appear as a result of ageing processes such as glycation, habitual sleeping positions, loss of body mass, sun damage, or temporarily, as the result of prolonged immersion in water. Age wrinkling in the skin is promoted by habitual facial expressions, aging, sun damage, smoking, poor hydration, and various other factors. In humans, it can also be prevented to some degree by avoiding excessive solar exposure and through diet.
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.
Dermabrasion is a type of surgical skin planing, generally with the goal of removing acne, scarring and other skin or tissue irregularities, typically performed in a professional medical setting by a dermatologist or plastic surgeon trained specifically in this procedure. Dermabrasion has been practiced for many years and involves the controlled deeper abrasion of the upper to mid layers of the skin with any variety of strong abrasive devices including a wire brush, diamond wheel or fraise, sterilized sandpaper, salt crystals or other mechanical means.
Pseudofolliculitis barbae (PFB) is a type of irritant folliculitis that commonly affects people who have curly or coarse facial hair. It occurs when hair curls back into the skin after shaving, causing inflammation, redness, and bumps. This can lead to ingrown hairs, scarring, and skin discoloration. PFB can be treated with various methods, including changing shaving habits, using topical creams or ointments, and undergoing laser hair removal. Prevention measures include proper shaving techniques, using sharp razors, and avoiding too close a shave.
Croton oil is an oil prepared from the seeds of Croton tiglium, a tree belonging to the order Euphorbiales and family Euphorbiaceae, and native or cultivated in India and the Malay Archipelago. Small doses taken internally cause diarrhea. Externally, the oil can cause irritation and swelling. Croton oil is used in Phenol-croton oil chemical peels for its caustic exfoliating effects it has on the skin. Used in conjunction with phenol solutions, it results in an intense reaction that leads to initial skin sloughing. Since croton oil is very irritating and painful, it is used in laboratory animals to study how pain works, pain-relieving and anti-inflammatory drugs, and immunology.
In cosmetics, skin toner or simply toner refers to a water-based lotion, tonic, or wash designed to cleanse the skin and prepare it for other skincare products, such as moisturizers and serums. Typically used on the face, toners remove any remaining impurities after cleansing, balance the skin’s pH, and hydrate the skin. They also serve to protect and refresh the skin, often containing ingredients that can soothe, moisturize, exfoliate, or target specific skin concerns like oil control or pore minimization.Unlike micellar water, which cleanses and removes makeup, toners are primarily used to balance the skin's pH and prepare it for further skincare applications.
In cosmetology, exfoliation is the removal of the surface skin cells and built-up dirt from the skin's surface. The term comes from the Latin word exfoliare. This is a regular practice within the cosmetic industry, both for its outcome of promoting skin regeneration as well as providing a deep cleanse of the skin barrier. Being used in facials, this process can be achieved by mechanical or chemical means, such as microdermabrasion or chemical peels. Exfoliants are advertised as treatments that enhance beauty and promote a youthful and healthy appearance.
Alpha hydroxy carboxylic acids, or α-hydroxy carboxylic acids (AHAs), are a group of carboxylic acids featuring a hydroxy group located one carbon atom away from the acid group. This structural aspect distinguishes them from beta hydroxy acids, where the functional groups are separated by two carbon atoms. Notable AHAs include glycolic acid, lactic acid, mandelic acid, and citric acid.
Skin care or skincare is a range of practices that support skin integrity, enhance its appearance, and relieve skin conditions. They can include nutrition, avoidance of excessive sun exposure, and appropriate use of emollients. Practices that enhance appearance include the use of cosmetics, botulinum, exfoliation, fillers, laser resurfacing, microdermabrasion, peels, retinol therapy, and ultrasonic skin treatment. Skin care is a routine daily procedure in many settings, such as skin that is either too dry or too moist, and prevention of dermatitis and prevention of skin injuries.
Hidradenitis is any disease in which the histologic abnormality is primarily an inflammatory infiltrate around the eccrine glands. This group includes neutrophilic eccrine hidradenitis and recurrent palmoplantar hidradenitis.
Artefill is a permanent injectable wrinkle filler, for the correction of smile lines. Artefill was approved by the U.S. Food and Drug Administration (FDA) as a medical device in October 2006. A prior version of the product called Artecoll has been marketed in Canada and Europe since the 1990s.
Steatocystoma multiplex, is a benign, autosomal dominant congenital condition resulting in multiple cysts on a person's body. Steatocystoma simplex is the solitary counterpart to steatocystoma multiplex.
Photorejuvenation is a skin treatment that uses lasers, intense pulsed light, or photodynamic therapy to treat skin conditions and remove effects of photoaging such as wrinkles, spots, and textures. The process induces controlled wounds to the skin. This prompts the skin to heal itself, by creating new cells. This process—to a certain extent—removes the signs of photoaging. The technique was invented by Thomas L Roberts, III using CO2 lasers in the 1990s. Observed complications have included scarring, hyperpigmentation, acne, and herpes.
A pimple or zit is a kind of comedo that results from excess sebum and dead skin cells getting trapped in the pores of the skin. In its aggravated state, it may evolve into a pustule or papule. Pimples can be treated by acne medications, antibiotics, and anti-inflammatories prescribed by a physician, or various over the counter remedies purchased at a pharmacy.
Facial care is a comprehensive process that involves a variety of products and routines aimed at maintaining the health, appearance, and radiance of the skin. The effectiveness of a facial care regimen depends on various factors such as skin type, sensitivity, age, hyperpigmentation, and acne. To achieve the best results, it is crucial to choose products that are suitable for your specific skin type and address any particular skin concerns you may have. There are many different forms of skin care treatments and practices, each offering unique benefits for the skin. Some popular forms of facial care include facial steaming, facial massage, and the use of masks. These treatments can help to cleanse, hydrate, and rejuvenate the skin, leaving it looking and feeling refreshed.
Salicylic acid is used as a medicine to help remove the outer layer of the skin. As such it is used to treat warts, skin tags, calluses, psoriasis, dandruff, acne, ringworm, and ichthyosis. For conditions other than warts, it is often used together with other medications. It is applied to the area affected.
