What is Hyperpigmentation?
Hyperpigmentation is the excess production of the skin pigment melanin, appearing as localised patches which are darker than the surrounding skin. The patches are typically non-raised, as the hyperpigmentation occurs beneath the top layer of skin.
Who gets it?
Hyperpigmentation occurs in all skin types, however people with darker skin tones are more prone to it. Those of Asian, African and Mediterranean origin can get it with greater frequency and severity.
What are the main causes?
Acne, Ageing, Sun damage, Pregnancy & Eczema are the most common causes.
What are the main types?
There are three main types of hyperpigmentation:
Post-Inflammatory Hyperpigmentation (PIH) – This occurs following skin injury e.g. from acne lesions or laser burns.
Melasma – This is caused by hormonal fluctuations, common, for example, during pregnancy,through use of birth control pills and hormone replacement therapy.
UV damage – UV light stimulates melanocyte activity, producing excess melanin. As Asian, Arabic and African skin is more exposed to the sun, this factor plays a larger role in darker skin hyperpigmentation.
