Melasma or skin hyperpigmentation is a condition that interferes with natural skin color and causes brown patches on skin. Excessive melanin production is the immediate cause of melasma. Overexposure to sun’s rays, hormonal changes, stress, thyroid, toxins, and birth control pills are some of the common causes of melasma. It is hard to distinguish between age spots and melasma but on closer looking you will notice that melasma is much darker, larger and is irregular in shape. Melasma can be cured effectively with home remedies. Here are some of the best home remedies for melasma and how to use them for best results.
