We all long for a smooth, even appearance across our skin and complexion. This can help to promote the appearance of health, youth and vitality. Caused by the overproduction of the skin pigment melanin, usually due to UV exposure or ageing, many people have dark spots on their faces. Many ask how to address areas that appeared to be affected by excessive melanin, including freckles, discolouration, age spots and scars. There are many different types of skin whitening products available, with the most popular being creams and soaps. There are also lotions, serums, gels, tonics, capsules and devices.
