Korean Cosmetics: Missha

Skin care encompasses a variety of techniques that promote skin integrity, improve skin attractiveness, and alleviate skin problems. They can include proper diet, avoiding excessive sun exposure, and using emollients appropriately. Cosmetics, botulinum, exfoliation, fillers, laser resurfacing, microdermabrasion, peels, retinol therapy, and ultrasonic skin treatment are among practices that improve look. Skin care is a daily practice in various situations, such as treating skin that is either too dry or too wet, preventing dermatitis, and treating skin injuries.

Skin care is used to treat wound healing, radiation therapy, and certain medicines.

Skin care lies at the crossroads of cosmetics and dermatology, a traditional medical profession; there is considerable overlap between both areas.

Korean Cosmetics are made up of a variety of chemical components originating from either natural or manufactured sources. Skin care cosmetics, such as cleansers, toners, serums, moisturizers, and balms, can be used to wash, exfoliate, and protect the skin while also renewing it. Shampoo and body wash, which are meant for more general personal care, can be used to cleanse the body. Cosmetics designed to improve one's appearance (makeup) can be used to conceal blemishes, enhance one's natural features (such as eyebrows and eyelashes), add color to a person's face, and, in the case of more extreme forms of makeup used for performances, fashion shows, and people in costume, can be used to completely change the appearance of the face to resemble a different person, creature, or omen. Cosmetics can also be intended to scent the body.

Though the legal definition of cosmetics is broader in most countries, in certain Western nations, cosmetics are generally understood to mean solely makeup items such as lipstick, mascara, eye shadow, foundation, blush, highlighter, bronzer, and a variety of other product kinds. Cosmetics are defined as items "designed to be applied to the human body for cleaning, beautifying, enhancing beauty, or modifying the look without damaging the body's structure or functions" by the Food and Drug Administration (FDA), which oversees cosmetics. The FDA expressly excludes pure soap from this wide definition, which includes any substance intended for use as an ingredient in a cosmetic product.

Cosmetics are items that are meant to cleanse or beautify, according to the Federal Food, Drug, and Cosmetic Act (for instance, shampoos and lipstick). Medication, which is intended to diagnose, cure, mitigate, treat, or prevent disease, or to affect the structure or function of the body (for example, sunscreens and acne creams), has its own category, though some products, such as moisturizing sunscreens and anti-dandruff shampoos, are regulated under both categories.

Skin care varies from dermatology in that it has a broader but less medical scope and includes non-physician practitioners such as estheticians and wound care nursing personnel. Skin care entails changes in human behavior as well as changes in the environment and working situations. Nonetheless, dermatology has taken over some areas of skin care, notably in the United States, and to a much lesser extent abroad, such as the United Kingdom.

Sun protection is an essential component of skin care. Though the sun is necessary for the human body to obtain its daily dosage of vitamin D, unprotected excessive sunlight can cause severe skin damage. UVA and UVB radiation in the sun's rays can induce sunburn to different degrees, premature aging, and an increased risk of skin cancer. UV rays can create uneven skin tone and cause the skin to dry out. It can even impair skin suppleness and promote the creation of sagging and wrinkles.

Sunscreen can protect the skin from sun damage; apply sunscreen at least 20 minutes before exposure and reapply every four hours. To achieve full coverage, apply sunscreen to all parts of the skin that will be exposed to sunlight, and apply at least a tablespoon (25 ml) to each leg, the face, chest, and back. Many tinted moisturizers, foundations, and primers now include SPF.

Sunscreens can be creams, gels, or lotions; their SPF value shows how efficient they are in protecting the skin from the sun's rays. There are sunscreens for every skin type; those with oily skin should choose non-comedogenic sunscreens; those with dry skin should choose sunscreens with moisturizers to help keep skin hydrated; and those with sensitive skin should choose unscented, hypoallergenic sunscreen and spot-test in an inconspicuous place (such as the inside of the elbow or behind the ear) to avoid irritation.
