Pigmentation
Sunspots and age spots are common examples of pigmentation which is characterised by the appearance of brown or darker patches on the skin. Often called melasma or hyperpigmentation depending on the area and cause.
Hyperpigmentation can occur due to inflammation following sun exposure, infection, acne spots and hormonal changes seen within the body in peri-menopause, menopause and pregnancy. The use of oral birth control pills, stress and thyroid disease can also cause melasma along with sun exposure.
