Frequently Asked Questions About Acne

The pigmentation side effect gradually disappears after the therapy is discontinued. Any side effect of a medication should be noted by the patient and brought to the attention of the physician. While most side effects are temporary they should be discussed with the physician and monitored. 1. My doctor is prescribing a topical retinoid for my acne. He said a retinoid is a substance related to vitamin A. If the drug is related to vitamin A, shouldn't vitamin A dietary supplements be helpful in getting rid of acne? Dietary vitamin A is essential to good health, especially vision. It has healthful effects in the skin. Large doses of vitamin A for the treatment of acne is not recommended on grounds of safety. The retinoids and retinoid-like substances used as topical treatments for acne are prepared especially for their potent effect on the shedding of cell lining in the sebaceous follicle. Their use should be monitored by a dermatologist. Dietary vitamin A has multiple health effects in the human body. Vitamin A is essential for good vision. Extreme vitamin A deficiency can result in blindness, usually accompanied by dry, scaly skin. Vitamin A overdose that far exceeds the Recommended Dietary Allowance (RDA) of 5,000 IU can have effects nearly as catastrophic. Extreme vitamin A overdose can cause the skin to blister and peel-an effect first seen in early North Pole explorers who nearly died after eating polar bear liver that has an extraordinarily high vitamin A content. Topical retinoids are usually prescribed as a treatment for moderate to severe acne. Side effects are chiefly dermatologic, including redness, scaling and dryness of the skin, itching and burning. These side effects can usually be managed by adjustment of the amount and timing of retinoid applied to the skin. Dose adjustment must be discussed with the dermatologist who prescribed the treatment. 2. Are there any acne treatments specifically for people with dark skin? Are there any treatments specifically harmful to dark skin? There are no acne treatments specifically for use on dark skin. Acne treatments are generally as safe and effective on dark skin as on light skin. Some treatments for acne scars may cause temporary lightening of dark skin. Acne is a common skin disease that has the same causes and follows the same course in all colors of skin. Very dark or black skin may be less well-moisturized than lighter skin. Topical anti-acne agents such as benzoyl peroxide that have a drying effect on the skin should be used under the supervision of a dermatologist. Benzoyl peroxide also is a strong bleach and therefore must be applied carefully to avoid inadvertent decolorization of a patch of hair, towels or clothing. Darker skin has a tendency to develop post-inflammatory hyperpigmentation (excessive skin darkening at places where the skin was inflamed). Severe inflammatory acne may result in dark spots. The spots resolve over time; a dermatologist may be able to recommend cosmetic measures to make the spots less apparent until they resolve. Some acne treatments, such as topical retinoids and azelaic acid, may also help fade the discoloration. Removal of acne scars by dermabrasion or chemical peeling may cause temporary lightening or darkening of dark skin in the areas of treatment. Scar treatment should be discussed with a dermatologist or dermatologic surgeon before it is undertaken. Alterations of melanin (dark pigments that give the skin its color) pigmentation such as vitiligo and melasma are not related to acne, but they may be present simultaneously with acne. The diagnosis and treatment of melanin pigmentation disorders such as vitiligo requires a dermatologist with knowledge and experience in treating these conditions. 3. Is acne that appears for the first time in adulthood different from acne that appears in adolescence? Acne has a specific definition as a disease of sebaceous follicles. This definition applies to acne that occurs at any age. However, it may be important to look for an underlying cause of acne that occurs for the first time in adulthood. Current understanding of the causes of acne vulgaris is described in the Main Text section Why and how acne happens. In brief summary, acne vulgaris develops when excessive sebum production and abnormal growth and death of cells in the sebaceous follicle result in plugging of follicles with a mixture of sebum and cellular debris and formation of comedones (blackheads and whiteheads). Bacteria in the follicles-chiefly Propionibacterium acnes, the most common bacterial colonist of sebaceous follicles-may contribute to the inflammation of acne by release of metabolic products that cause inflammatory reaction. The pathogenic events, which cause disease, in the sebaceous follicle are believed to be due in large degree to changes in levels of androgenic (male) hormones in the body-a circumstance usually associated with growth and development between ages 12 and Jesica Bacalla writes for Acne Article [http://www.acneblogs.net] for more info visit [http://www.acneblogs.net]
