Treatments and drugs
By Mayo Clinic staffThere's no specific treatment for acanthosis nigricans. However, treating any underlying conditions may cause the skin changes to fade, such as:
- Losing excess pounds if you're overweight
- Making dietary changes, such as cutting back on starches and sugars
If you're concerned about the appearance of your skin, your doctor may recommend these treatments:
- Prescription creams or lotions to lighten the affected areas, such as those containing modified vitamin A products (Retin-A, others)
- Oral medications, such as isotretinoin (Accutane, Sotret)
- Fish oil supplements
- Dermabrasion or laser therapy, which may help reduce the thickness of certain affected areas
Thick lesions can have a bad odor. Using antibacterial soaps or a topical antibiotic may help.
