Hi,
This is a condidtion called Hyperkeratosis.Hyperkeratosis is a thickening of the skin that occurs in women with brown skin. It is due to excessive accumulation of keratin in the outer layers of the skin. Thickening of the skin protects it against rubbing, pressure and irritation. The majority of the forms of hyperkeratosis are painless. Although hyperkeratosis may occur anywhere on the skin, there are several areas that are typically involved.
Treatment of hyperkeratosis depends on the type, location, severity and cause. Most treatments are aimed at softening the keratin and removing the thickened skin. This may be accomplished with topical creams that contain as the active ingredient salicylic acid, alpha-hydroxy acid (lactic or glycolic acid), urea, or tretinoin. In brown skin, discoloration often accompanies the hyperkeratosis and skin lightening creams may also be used like hydroquinone.
