What are moles and what causes them?
Moles are small, coloured spots on the skin. Moles are formed by clusters of pigmented cells known as melanocytes, which give skin pigment their dark colour. They generally appear during childhood and adolescence in Singapore. Most people develop around 10 to 40 moles, some of which may change in appearance or fade away with time. Whether or not moles darken is dependent on factors such as hormones, genetic predisposition, and sun exposure. This also explains why pregnant women and teenagers tend to have a higher chance of moles growing or darkening.
