Increased pigmentation of these areas may be a normal occurrence of aging or may represent an hormonal imbalance or be caused by chronic irritation.  Your doctor should be able to perform an examination and order the necessary blood test to determine why this is happening.  There are skin bleaching creams used to lighten the skin that may be appropriate depending on the cause.  Seeing a Dermatologist may be helpful.  Thank you for your question.  J.
