The sun is the culprit in many cases of hyperpigmentation; however, what you probably don't know is that UV rays aren’t the only cause of brown spots on the skin. Along with accumulative sun exposure, other causes of hyperpigmentation include: heat, pregnancy, birth control pills and menopause (because heat and hormones can cause an increase in melanin production).

To help resist dark spots, maintain healthy skincare practices that incorporate regular exfoliation and the daily use of a sunscreen with an SPF of 15 or more. It is possible for hyperpigmentation to darken; using sun protection is one way to prevent more pronounced spots. In addition to these preventive measures, apply a topical antioxidant to keep your skin thoroughly protected.
