Cleansing is a standard step in skin care routines. Skin cleaning include some or all of these steps or cosmetics:
Toners are used after cleansing the skin to freshen it up, boost the appearance of one's complexion, and remove any traces of cleanser, mask, or makeup, as well to help restore the skin's natural pH. They are usually applied to a cotton pad and wiped over the skin, but can be sprayed onto the skin from a spray bottle. Toners typically contain alcohol, water, and herbal extracts or other chemicals depending on skin type whether oily, dry, or combination. Toners containing alcohol are quite astringent, and usually targeted at oily skins. Dry or normal skin should be treated with alcohol-free toners. Witch hazel solution is a popular toner for all skin types, but many other products are available. Many toners contain salicylic acid and/or benzoyl peroxide. These types of toners are targeted at oily skin types, as well as acne-prone skin.[citation needed]
Facial masks are treatments applied to the skin and then removed. Typically, they are applied to a dry, cleansed face, avoiding the eyes and lips.
Clay-based masks use kaolin clay or fuller's earth to transport essential oils and chemicals to the skin, and are typically left on until completely dry. As the clay dries, it absorbs excess oil and dirt from the surface of the skin and may help to clear blocked pores or draw comedones to the surface. Because of its drying actions, clay-based masks should only be used on oily skins.
Peel masks are typically gel-like in consistency, and contain acids or exfoliating agents to help exfoliate the skin, along with other ingredients to hydrate, discourage wrinkles, or treat uneven skin tone. They are left on to dry and then gently peeled off. They should be avoided by people with dry skin, as they tend to be very drying.
Sheet masks are a relatively new product that are becoming extremely popular in Asia. Sheet masks consist of a thin cotton or fiber sheet with holes cut out for the eyes and lips and cut to fit the contours of the face, onto which serums and skin treatments are brushed in a thin layer; the sheets may be soaked in the treatment. Masks are available to suit almost all skin types and skin complaints. Sheet masks are quicker, less messy, and require no specialized knowledge or equipment for their use compared to other types of face masks, but they may be difficult to find and purchase outside Asia.
Exfoliants are products that help slough off dry, dead skin cells to improve the skin's appearance. This is achieved either by using mild acids or other chemicals to loosen old skin cells, or abrasive substances to physically scrub them off. Exfoliation can even out patches of rough skin, improve circulation to the skin, clear blocked pores to discourage acne and improve the appearance and healing of scars.
Chemical exfoliants may include citric acid (from citrus fruits), acetic acid (from vinegar), malic acid (from fruit), glycolic acid, lactic acid, or salicylic acid. They may be liquids or gels, and may or may not contain an abrasive to remove old skin cells afterwards.
Abrasive exfoliants include gels, creams or lotions, as well as physical objects. Loofahs, microfiber cloths, natural sponges, or brushes may be used to exfoliate skin, simply by rubbing them over the face in a circular motion. Gels, creams, or lotions may contain an acid to encourage dead skin cells to loosen, and an abrasive such as microbeads, sea salt, sugar, ground nut shells, rice bran, or ground apricot kernels to scrub the dead cells off the skin. Salt and sugar scrubs tend to be the harshest, while scrubs containing beads or rice bran are typically very gentle.
Moisturizers are creams or lotions that hydrate the skin and help it to retain moisture; they may contain essential oils, herbal extracts, or chemicals to assist with oil control or reducing irritation. Night creams are typically more hydrating than day creams, but may be too thick or heavy to wear during the day, hence their name. Tinted moisturizers contain a small amount of foundation, which can provide light coverage for minor blemishes or to even out skin tones. They are usually applied with the fingertips or a cotton pad to the entire face, avoiding the lips and area around the eyes. Eyes require a different kind of moisturizer compared with the rest of the face. The skin around the eyes is extremely thin and sensitive, and is often the first area to show signs of aging. Eye creams are typically very light lotions or gels, and are usually very gentle; some may contain ingredients such as caffeine or Vitamin K to reduce puffiness and dark circles under the eyes. Eye creams or gels should be applied over the entire eye area with a finger, using a patting motion.
