Brief Answer:
Looks like acanthosis nigricans.

Detailed Answer:
Hello,

I reviewed your photos carefully.
It looks very much like Acanthosis nigricans, which is a benign condition, often asymptomatic but with cosmetic concerns like in your case.

The reason why I asked if you had obesity or any chronic problem, is because it is often cause of obesity, diabetes or insulin resistency. By treating these problems, the acanthosis will clear by itself.

If you are attempting to improve the appearance of lesions through excessive scrubbing of the affected skin during bathing , I would not encourage it, since it may result in lichenification (thickening of the skin) and worsening in hyperpigmentation.

If after ruling out or treating the conditions I mentioned above, the reversal of the acanthosis nigricans is impossible, then topical therapies that normalize epidermal proliferation, such as topical retinoids and topical vitamin D analogs can be used. In this case, you may need to see a dermatologist who can prescribe one of those.

I hope this is helpful and your question has been answered.

Kind regards,
Dr. Papaqako
