What is hyperpigmentation?
Melanin is the pigment responsible for giving your skin its colour; pigmentation refers to the colouring of the skin. Hyperpigmentation happens when your skin produces more melanin than normal. The excess pigment gives the affected area a darker look than the skin around it leading to uneven pigmentation - otherwise known as hyperpigmentation.
What causes hyperpigmentation?
Exposure to the sun. Protecting the skin with high SPF sunscreen from harmful UV rays is the best way of preventing sun pigmentation or stopping hyperpigmentation from becoming darker. Other types of hyperpigmentation form after an injury or skin inflammation, such as a cut, burns, acne, or lupus. These can occur anywhere on the body.
Hormonal changes, age and inflammation. Certain medical conditions or medications can also cause hyperpigmentation. (Always seek professional medical advice if you think this could be something you have).
