Melasma and Hyperpigmentation; Causes of Pigmentation and Skin Darkening
Melasma is characterized by an uneven and patchy pigmentation that arises from a variety of causes, including:
- Sun Exposure
- Chronic or active inflammation
Unlike typical sun-induced suntans, hyperpigmentation from melasma is not transient. The discoloration is chronic and progressive. The pigmentation results from a genetically-determined hypersensitivity of receptors on the melanocytes on certain key areas of the face, including the jawlines, forehead, and cheeks.
The key element of melasma is that it does not subside with time. The discoloration is patchy and undermines the even complexion of one's native skin color. From a clinical perspective, the melasma is a significant sign of facial aging and reduces the smoothness of color that we are born with.
A basic clinical analysis is made by analyzing one's native skin tone and determining the severity of overlying pathologic pigmentation.
