Antiperspirant allergies are rare but is a allergic reaction mostly experienced by women, especially those with acanthosis nigracans, a skin disorder. Acanthosis nigricans can begin at any age and generally causes light brown velvety-like markings on the neck, under the arms or in the groin area. It is still unknown why it is seen more in women who are overweight.

Causes of Acanthosis Nigricans

• Addison disease (deficiency of hormones from the adrenal gland)
• Disorders of the pituitary gland within the brain
• Growth hormone therapy
• Hypothyroidism (low levels of thyroid hormone in the thyroid gland)
• Taking cholesterol medications (including nicotinic acid)
• Taking oral contraceptives
• Using certain skin care products such as antiperspirants

Diagnosing Acanthosis Nigricans

The condition may only be diagnosed by a health professional with a thorough a physical examination and medical history exam.  Blood work is also helpful in investigating the primary cause of acanthosis nigricans.

Treating Acanthosis Nigricans

Treating acanthosis nigracans is usually achieved though weight loss and exercise.  Increased insulin by a poor diet has also been connected to acanthosis nigracans so eating a healthy diet can lead to improvement and has been reported to cure the disorder completely.

There are topical treatments such as Retin-A, urea, alpha hydroxy acids and salicylic acid prescriptions.  Dermabrasion has also been used to reduce the raised portion of the affected skin. Certain oral medications have also been reported to make acanthosis nigracans worse and should be discussed with your doctor.
