Hyperpigmentation occurs when melanin – the pigment that gives skin, hair and eyes their natural colour – is overproduced in certain areas. This causes localised dark spots or patches on the skin. These patches can be light brown to black in colour and will often vary in size and shape. Freckles, age spots and post-acne marks are all examples of hyperpigmentation.

Hyperpigmentation is most commonly seen in medium to dark skin tones. This is because darker skin has more melanin and therefore is more susceptible to irregularity.

3 Main Categories of Hyperpigmentation

  1.  Hormonal-when oestrogen is elevated above a normal level, it can lead to a condition known as melasma that causes large areas of skin to darken. This is why many women notice flat, dark patches of skin developing during their pregnancy or after starting the contraceptive pill.

  2. Inflammatory- post-inflammatory hyperpigmentation (PIH) is what occurs after a pimple or bite has finished healing. It is essentially the skin’s natural response to any injury that causes the skin to become inflamed. As the inflammation subsides and the lesion begins to heal, the skin can often produce too much melanin causing the formerly-damaged skin to darken.

  3. Sun Induced- this typically refers to age. This kind of hyperpigmentation is caused by sun damage.
