Most people experience dark skin in the armpit area and even after repeated cleaning, the dark skin tone does not seem to go away. There are a number of reasons for the presence of dark skin in the underarms and it is always advisable to get a doctor's opinion before you seek to lighten the skin on your own. A number of medical conditions are responsible for the appearance of dark skin around the underarms; a number of lifestyle factors can also contribute to the condition.
If you are in the habit of wearing tight clothes or removing the hair from the area through the use of razor blades, it can lead to an uneven skin tone in the armpits. Tight clothes cause the skin to rub against the fabric thus creating skin irritation and over a period of time leading to dark skin. Shaving the armpits is also known to cause dark skin around the armpits; this is due to the fact that while shaving, only the hair that is above the hair follicles is removed. The hair follicles beneath the skin lead to ingrown hair that is usually observed from the outside, giving off the appearance of darkened skin. Moreover certain razor blades or shaving creams can cause an adverse reaction to the delicate skin area at the armpits. Sometimes the use of certain deodorants, cosmetic applications or perfumes can also cause the skin to darken in the armpits.
If none of these conditions are believed to cause the skin darkening, it is possible that you must be experiencing a medical condition causing the hyper pigmentation. One such medical condition is known as acanthosis nigricans, which is a skin disease, characterized by dark wart like patches in the body folds, and can be either benign or malignant in nature.
Being overweight can also cause skin darkening around the armpits when higher levels of insulin are produced in people with diabetes or insulin regulation disorders. Such conditions cause dry skin and lead to pigmentation. In either case, it is advisable to visit your general practitioner for correct diagnosis and the right way to treat the condition, instead of treating only the darkened skin area. If you are experiencing excessive weight problems, the doctor would advise you on diets or weight loss programs and also prescribe medication to help lower the insulin level.
Once your doctor has realized the cause of the dark patches, you may be required to use topical applications in addition to your primary medication to treat the condition. Seek the advice of the dermatologist to understand the dosage and the duration of the treatment.
