Skin Allergies
If an individual is suffering from skin allergies, then the chances of developing melasma are higher in that particular individual. Several factors become the cause of skin allergies and irritate the skin surface. Moreover, certain medications also play a role in aggravating the skin, such as anti-seizure medications, birth control pills, tetracyclines, and hormonal replacement therapy. At the same time, some cosmetic products make your skin sensitive to the UV rays coming from the sun and might result in the development of melasma.
