Melasma and Age Spots are the two most commonly known types of skin pigmentation caused by an abnormal increase in melanin (pigment cells) as a result of photo aging (sun exposure).
Melasma is characterised by dark spots or blotches on the face, forehead and neck. This is usually caused by sun exposure and also associated with the hormonal changes experienced by women during pregnancy.
Sun spots, age spots, or liver spots are benign flat brown spots that appear as large brown freckles on the skin and caused as a result of chronic exposure to the sun. It most commonly occurs in mature skin which has a tendency to suffer from sun damage. Our findings indicated that most men in their thirties and beyond, who travel back from oversea countries where the UV rays, are intense (such as Australia) and without using a sun block will suffer from pigmentation on the cheeks or forehead.
