Dark Pigmentation Around Neck

Dark pigmentation around the neck is known as  Acanthosis nigricans. It  is a skin condition characterized by dark, thick, velvety skin in body folds and creases. Most often, acanthosis nigricans affects your armpits, groin and neck.

With acanthosis nigricans, you may naturally be concerned about the appearance of your skin. Some steps may help lighten the affected areas of your skin. There is no specific treatment for acanthosis nigricans , but treating any underlying conditions, such as diabetes and obesity, may cause the changes in your skin to fade.

Skin changes.
Skin changes are the only signs of acanthosis nigricans. You'll notice dark, thick, velvety skin in body folds and creases  usually in your armpits, groin and neck. Sometimes the lips, palms or soles of the feet are affected as well.
Slow progression. The skin changes appear slowly, sometimes over months or years.
Feasible itching.  The affected areas may itch.

Acanthosis nigricans is often associated with conditions that increase your insulin level, such as type one diabetes or being overweight. If your insulin level is high, the additional insulin may trigger activity in your skin cells. This may cause the characteristic skin changes.
Solution for dark pigmentation
As i have told you there is no treatment for this. Doctors will ask you to reduce the weight. Many people would have tried all the home remedies in this world like margosa leaves, sandal powder, bleach and loofah cleaning. But it is very difficult to get result with this.
Homeopathy is the best medicine for this
I have seen my relative who had this problem feels better after taking homeopathy treatment. It is not costly also. You can feel the difference within two months. Anyone who have this problem can and should definitely try homeopathy. I am not a homeopathy specialist. But i have seen my relative after taking homeopathy her dark pigment around the neck has reduced to a large extent.
