Red blemishes caused by acne, including papules, pustules and cysts, may be difficult to get rid of depending on their cause and severity. You can treat some blemishes with home remedies, while others should be treated by a dermatologist. Red blemishes can appear anywhere on the body, but tend to occur mainly on the face, neck and back. According to the Mayo Clinic, some blemishes can cause scarring if not treated.
Wash the affected area carefully and often with warm water and a soft cloth. Be careful not to scrub which may make matters worse.
Avoid eating foods high in carbohydrates with a high glycemic index such as white bread and pizza, which can increase blood sugar levels. The Mayo Clinic believes there is a link between carbohydrates and acne. Opt for whole grains, unsweetened beverages and minimally processed foods to keep blood sugar levels down.
Exfoliate the affected area by shaving with a razor and mild shave cream. Shaving removes the top layer of dead skin that may be blocking hair follicles, which may cause blemishes to develop. It isn't necessary to have hair on the skin for this type of exfoliation. Use shaving cream to avoid nicks on the skin and always use a clean razor.
Treat the red blemish immediately with over-the-counter acne medications that contain salicylic acid and benzoyl peroxide. Some or all of these acne treatments may not be suitable for sensitive skin.
Seek medical attention from a dermatologist if over-the-counter medications don't seem to work. Prescription topical medications may clear up the blemishes. A dermatologist can prescribe oral antibiotics or oral birth control pills for severe cases of acne.
Use Isotretinoin as a last resort to treat acne and then only under the watchful eye of a physician. According to the federal Food & Drug Administration, the drug's side effects can include birth defects and increased thoughts of suicide. Because of the risk of birth defects, women of childbearing age cannot get a prescription for Isotretinoin unless they follow a program monitored by the FDA and their doctor. This acne medication is only for those with serious acne that hasn't improved with other treatments.
