Nickel Allergy Acne Acne is a disorder of the hair follicles caused by the clogging of pores by dead skin cells and oil produced by the sebaceous glands. It is most prevalent among teenagers, whose increased hormone production leads to more oil secretions and faster skin-cell turnover; however, acne can occur at any age. Acne is also common in young women experiencing the rise and fall of hormone levels associated with the menstrual cycle. There is evidence of a genetic predisposition for acne among some families. Stress may significantly affect acne. There is no scientific evidence to support the claim that sugary and high fat foods cause acne. Dermatitis/Eczema Although the terms are often used interchangeably, dermatitis and eczema encompass a wide range of skin inflammations and irritations. Dermatitis and eczema are characterized by a recurring itchy rash, usually flaring up in the presence of external triggers. These triggers are not the same for every person. Approximately 10 to 20 percent of the world’s population is affected by dermatitis or eczema at some point during childhood. Though an estimated 15 million people in the United States are afflicted with some type of eczema or dermatitis, most cases clear up between the ages of five and 15. Eczema is not contagious and currently cannot be cured. The cause of eczema and dermatitis is not known, but studies have shown that many people with a family history of allergies are afflicted. Moles & Warts Moles and warts are skin lesions that can be benign or malignant. Moles are the most common skin growth seen on humans. They can be present at birth or can develop throughout life Warts are caused by a virus and are recurring. They appear most often on the hands. Removal of skin lesions for cosmetic reasons is one of the most common procedures performed by dermatologists. Warts and moles can be removed by surgical excision, cryotherapy (freezing) or repeated application of special creams. Suspicious skin lesions, especially moles, should be biopsied for evaluation. Some moles can be evidence of skin cancer. Psoriasis Psoriasis is a chronic skin disease characterized by skin lesions and discomfort. The skin lesions caused by psoriasis are red and elevated, overlaid with thick, silvery scales. Psoriasis currently affects more than five million people in the United States. There is evidence of a genetic predisposition for psoriasis. Triggers other than genetics can include stress, strep infection and some medications. Psoriasis can lead to the development of arthritis.
