Skin Influenced By Age, Ethnicity, Environment, Heredity
Conditions that irritate, clog, or inflame your skin can cause serious problems. Many skin problems, such as acne, also affect your appearance. Here are the key facts about some of the most common skin problems:
Acne: This is the most common skin condition that affects human beings. While it mostly affects teenagers who are undergoing hormonal changes, many adults suffer with acne as well. Acne ranges in severity, requiring topical treatment in some individuals and systemic treatment in others. Acne can cause scarring as well. If you have mild or moderate acne, you may be able to treat it with cleansers, soaps, or astringents that are widely available over the counter. You can also use alpha-hydroxy acids (such as salicyclic acid) or benzoyl peroxide. If you have a more severe case of acne, you may require systemic treatment, which includes the administration of oral antibiotics, oral vitamin A compounds, or hormonal therapies. Your personal skin care treatment depends upon the cause of your acne, which can include bacteria, genetics, hormones, clogged pores or a combination of those factors.
Age spots or freckles: Age spots or liver spots (lentigines) and freckles (ephelides) are commonly caused from sun exposure. Age spots can occur in all skin types, typically arising later in life; freckles usually occur in people with fair skin. There are several ways to treat each, including hydroquinone and tretinoin. However, hydroquinone is not suitable treatment for persons with darker skin. If you have darker skin, you should plan to use a treatment that contains Kojic acid or vitamin C.
No matter who you are or what your ethnicity, your skin will require different care as you age. You will likely experience increased dryness, changes in facial contour, changes in hair growth, and decreased sweating. These are the impacts of the aging process. However, several treatments have proven effective. These include alpha hydroxy acids and vitamin A.
Dark skin: If you are African American, Native American, Asian, Hispanic or Southern European, you may want to avoid certain treatments. Those with sensitive skin should be especially cautious. If you use products with alpha-hydroxy acids, hydroquinones or tretinoin, you may risk hyperpigmentation (chemical reactions that can cause the creation of extra pigment, which may result in darker spots). If you have darker skin, you should plan to use a treatment that contains Kojic acid or vitamin C.
Eczema: This itchy, irritating skin condition comes in many forms and can be triggered by a variety of factors, including allergies, environmental factors, or family history. The raised, inflamed skin can appear anywhere on your body, including your face, legs, arms or neck. It can be treated with coal tar, steroid creams, or topical immunomodulators (TIMs), a class of anti-inflammatory drugs that are non-steroidal. For worse cases of eczema, you may require oral antibiotics, antihistamines or oral corticosteroids. As with other skin conditions, be sure to receive a proper diagnosis from a dermatologist for proper treatment guidelines.
Hives: Red and sometimes itchy bumps on your skin. An allergic reaction to a drug or food usually causes them. People who have other allergies are more likely to get hives than other people. Other causes include infections and stress. Hives are very common. They usually go away on their own, but if you have a serious case, you might need medical help.
Melasma: There are a number of treatments for this discoloration condition, also known as chloasma, which causes brown or tan patches on the face and neck. The condition is aggravated by sun exposure, but does not cause redness or swelling. If you think you have melasma, but you have not visited a dermatologist, it is important to receive an official diagnosis before beginning any treatment. This condition is most common among women who are on birth control pills, pregnant, or taking hormone replacement therapy. However, men also get melasma. This condition is commonly treated with hydroquinone, kojic acid, azelaic acid, L-ascorbic acids (vitamin C), or mandelic acid. To ensure effective treatment, you should use a sunscreen at all times.
Moles: Growths on the skin. They happen when cells in the skin, called melanocytes, grow in a cluster with tissue surrounding them. Most people have between 10 and 40 moles. A person may develop new moles from time to time, usually until about age 40. About one out of every 10 people has at least one unusual (or atypical) mole that looks different from an ordinary mole. They may be more likely than ordinary moles to develop into melanoma, a type of skin cancer. Because of this, you should have a health care professional check your moles if they look unusual, grow larger, change in color or outline, or in any other way.
Rashes (basic dermatitis): Dry and itchy skin; Rashes on the face, inside the elbows, behind the knees, and on the hands and feet. Your doctor will help you develop a good skin care routine, learn to avoid things that lead to flares, and treat symptoms when they occur.
Rosacea: This skin disease causes an array of symptoms, including redness and puffiness on several areas of the face, including cheeks and nose; in later stages, rosacea may cause small, visible blood vessels on the face, bumps or pimples on the face. Before seeking treatment, you should be officially diagnosed with this chronic condition, for which there is no cure, but there are available treatments. Rosacea can be treated with topical metronidazole, retinoids, azelaic acid, salicylic acid, mandelic acid or vitamin C. Oral antibiotics may be effective in more severe cases. It is important to realize that rosacea is a condition that can worsen if treatment is ignored or delayed. You should consult with your dermatologist to determine what treatment will work best for you.
Skin Cancer: Skin cancer is the most common form of cancer in the United States. The two most common types are basal cell cancer and squamous cell cancer. They usually form on the head, face, neck, hands, and arms. Another type of skin cancer, melanoma, is more dangerous but less common.
Wrinkles: Your skin changes as you age. You might notice wrinkles, age spots, and dryness. Sunlight is a major cause of skin aging. Cigarette smoking also contributes to wrinkles. The wrinkling increases with the number of cigarettes and years a person has smoked. Many products claim to revitalize aging skin or reduce wrinkles, but the Food and Drug Administration has approved only a few for sun-damaged or aging skin. Various treatments soothe dry skin and reduce the appearance of age spots.
