How do remove blackness from the neck?

Answer 1

A black ring around the neck that doesn't appear to have any cause can be a sign of acanthosis nigricans, a skin condition that is characterised by dark patches of skin that sometimes have a raised, soft (often velvety) texture. Acanthosis nigricans affects other parts of body than the neck: primarily the armpits, between the breasts on women, and sometimes around the bellybutton and on the inner thighs. Occasionally other areas, such as the forehead and the soles of the feet, are affected.

The causes of acanthosis nigricans are unclear, but it appears to often occur in conjunction with high insulin levels and excess weight. One theory is that excess insulin affects melanocyte production, creating patches with high melalin content.

If you are overweight, following a healthy diet can be very helpful, both to your weight and your insulin levels, which in turn can improve the appearance of the dark patches.

If you have no problems with your weight, it may be helpful to see a dermatologist. They may prescribe a cream to put on the area, possibly one containing tretinoin. In extreme cases, dermabrasion or laser therapy may be considered.

Very rarely, acanthosis nigricans can be a symptom of a more serious condition. If you are at all worried, see your doctor.
