Radiation induces skin reactions in the treated area, particularly in the axilla, head and neck, perineum and skin fold regions. 2001 American Society for Clinical Nutrition Nutritional skin care: health effects of micronutrients and fatty acids Esther Boelsma, Henk FJ Hendriks, and Len Roza.It is susceptible to interruption or failure that creates non-healing chronic wounds.
Wound healing is a complex and fragile process in which the skin repairs itself after injury. There is limited evidence that moisturising soap bar combinations of water soak, oil soak, and lotion are effective in maintaining the skin integrity of elderly people when compared to standard care. Moisturizers with humectants helped with skin dryness, and skin barrier occlusive reduced skin injuries. A literature review of studies that assessed maintenance of skin integrity in the elderly found most to be low levels of evidence, but the review concluded that skin-cleansing with synthetic detergents or amphoteric surfactants induced less skin dryness than using soap and water. Skin problems including pruritus are common in the elderly but are often inadequately addressed. Skin ageing is associated with increased vulnerability. There are sunscreens available to suit every skin type in particular, those with oily skin should choose non-comedogenic sunscreens those with dry skins 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 ensure that it does not irritate the skin. Sunscreens may come in the form of creams, gels or lotions their SPF number indicates their effectiveness in protecting the skin from the sun's radiation. Many tinted moisturizers, foundations and primers now contain some form of SPF. Sunscreen should be applied to all areas of the skin that will be exposed to sunlight, and at least a tablespoon (25 ml) should be applied to each limb, the face, chest, and back, to ensure thorough coverage. Sunscreen can protect the skin from sun damage sunscreen should be applied at least 20 minutes before exposure, and should be re-applied every four hours. UV exposure can cause patches of uneven skin tone and dry out the skin.It can even reduce skin's elasticity and encourage sagging and wrinkle formation. Ultraviolet (UVA and UVB) radiation in the sun's rays can cause sunburn in varying degrees, early ageing and increased risk of skin cancer. Though the sun is beneficial in order for the human body to get its daily dose of vitamin D, unprotected excessive sunlight can cause extreme damage to the skin. Sun protection is an important aspect of skin care. Immersion in water seems superior to washing alone, and use of synthetic detergents or mild liquid baby cleansers seems comparable or superior to water alone. Nevertheless, the pediatric and dermatological communities have not reached consensus on best cleansing practices, as good quality scientific evidence is scarce. Guidelines for neonatal skin care have been developed. Skin care includes modifications of individual behavior and of environmental and working conditions. Skin care differs from dermatology by its inclusion of non-physician professionals, such as estheticians and wound care nursing staff. A separate category exists for medications, which are intended to diagnose, cure, mitigate, treat, or prevent disease, or to affect the structure or function of the body (for instance, sunscreens and acne creams), although some products, such as moisturizing sunscreens and anti-dandruff shampoos, are regulated within both categories. The US Federal Food, Drug, and Cosmetic Act defines cosmetics as products intended to cleanse or beautify (for instance, shampoos and lipstick).
Skin care is at the interface of cosmetics, and dermatology.
