Obesity may also lead to dark skin, especially on the thighs and buttocks. Stretch marks may develop on the skin if there is sudden weight gain. These marks may cause the dermis of the skin to break down, resulting in the appearance of purplish scars which appear as dark patches on the skin. Another factor that may contribute to dark skin on the inner thighs is the prolonged use of birth control pills. Skin pigmentation may be one of the side effects of intake of birth control pills. A skin disorder called acanthosis nigricans results in dark patches on the body, especially in areas where there are skin folds. Individuals with polycystic ovary syndrome are also more susceptible to skin pigmentation and are likely to have patches of dark skin on the body.
