Acanthosis Nigricans is a skin pigmentation disorder characterized by dark, velvety patches that develop in specific body areas. In addition to skin folds, these patches may appear on the neck, elbows, groin and shoulders, underarms, knees, knuckles, groin, and face. Pigmentation on the face, neck, and other body areas can indicate any underlying medical condition, such as obesity or diabetes. Hormonal imbalance, excess of insulin in the blood, genetics, or medications such as oral contraceptive pills or corticosteroids can cause Acanthosis nigricans.

Acanthosis nigricans are characterized by black spots on the skin or dark patches that are darker and thicker than normal. The primary symptom of Acanthosis Nigricans is the presence of dark, thickened patches of skin. These patches typically have a velvety or rough texture and may appear brown, black, or gray. The affected areas may also feel itchy or irritated, develop skin tags, and have an odor.

The most commonly affected areas include the armpits, neck, groin, and face. The severity of the condition can vary from person to person, with some individuals experiencing mild patches while others have more extensive and noticeable discoloration.

How To Deal With Acanthosis Nigricans? 

Check with your doctor to know the exact cause of acanthosis nigricans. The doctor can provide appropriate treatment recommendations once the underlying cause of Acanthosis nigricans has been identified. As the cause is addressed, the dark spots on the skin should gradually fade over time. But it's a time-consuming process, so you need to be patient. However, if you want to accelerate the healing process of damaged skin, we recommend using ThriveCo Dark Patches Corrector. This triple-action pigmentation treatment formula helps with melasma and skin pigmentation by accelerating skin cell turnover, exfoliating dark spots, and down-regulating melanocytes, lightening dark spots on the face and other parts within six weeks. Apart from using Dark Patches Corrector for lightening hyperpigmentation on the skin, you should consult a doctor to find out the root cause of acanthosis nigricans for effective pigmentation treatment.
