Sun, hormones, meds: Most common causes of increased pigmentation are sun exposure, hormones (ie: pregnancy, fertility treatments, oral contraceptives, hormonal replacement therapy), and medications (ie: minocycline, tetracycline, doxycycline, sulfa drugs) or combination thereof. Certain diseases associated with hormonal imbalance such as addison's or cushing's can also cause excess pigment.
