HCS 1100 SLOs: 5 and 6

 Protection from the sun – avoiding times of high sun intensity and wearing protective clothing or sun screen.  Good nutrition- a complete well balanced diet provides nutrients needed for cell regeneration  Good circulation- regular exercise allows good blood flow which brings oxygen and nutrients to the tissues and carries away waste materials

 Care of damaged skin – injuries to the skin should be cleaned and bandaged to keep out infection  Regular cleaning removes dirt, dead skin debris and sustains a slightly acid environment that inhibits bacterial growth

 Loss of fat and collagen in underlying tissue leads to wrinkles around eyes and mouth  The dermis becomes thinner and skin may become transparent and lose elasticity  Localized areas of extra pigmentation causing brown spots or liver spots especially on areas exposed to sun  Circulation to the dermis decreases so skin appears paler

 Hair does not replace itself as rapidly and becomes thinner at the scalp  Decreased melanin production leads to grey or white hair  Hair texture changes and hair shaft becomes less dense and drier due to less sebum production  Sweat glands decrease leading to less perspiration so elderly can not cool themselves as easily

 Elderly are more sensitive to cold because of less fat under the skin and poorer circulation  Fingernails may flake, become brittle or have ridges  Toe nails may become thicker and discolored

 Dermatitis – inflammation of the skin usually due to contact with an irritant such as the oil of poison oak or poison ivy plants, detergents, strong acids or other chemicals  Treatment – remove the irritant and thorough washing of the affected area

 Eczema – is characterized by intense itching and skin inflammation. The affected areas show redness, blisters, papules and scaling or crusting of the skin surface.  Eczema usually first occurs in childhood and can continue with recurring bouts in adulthood  Skin may be excessively sensitive to many soaps, detergents, rough fabrics or perspiration

 Psoriasis is a chronic overgrowth of the epidermis leading to large, sharply outlined, red, flat areas (plaques) covered with silvery scales  May be a hereditary issue or an immune disorder may be involved  Treatment: use of a topical corticosteroid and exposure to UV light

 Mainly caused by over exposure to sunlight  Most common among people with fair skin  Basal cell and squamous cell carcinomas arise in the epidermis and usually appear on the face, neck and hands – usually curable when detected early

 Melanoma is a cancer tumor of the melanocytes.  Usually originates in a mole or birthmark  Characterized by uneven color and shape  You have a better chance of getting this kind of skin cancer if you have had a severe blistering sunburn

 An acute contagious disease of staphylococcal origin  A blister-like lesion that becomes filled with pus and contains millions of virulent bacteria  Most frequently found among poor and undernourished children

 Herpes simplex virus – also known as cold sores form watery vesicles on the skin and mucous membranes  Type 1 herpes causes lesions around the nose and mouth  Type 2 herpes is responsible for genital infections
