Acanthosis nigricans represents increased skin thickness on the neck!
It is often associated with insulin resistance, diabetes, and polycystic ovarian syndrome (PCOS) due to increased insulin-like growth factor (IGF) production. You may want to see your doctor first to make sure there is no underlying disease!
The best treatments help to normalize the skin thickness by exfoliating or increasing cell turnover
Retinoids, like differin gel, and exfoliants like amlactin are particularly helpful!
