Pigmentation

Freckles: Freckles are small spots of concentrated melanin and can appear in a variety of colours such as brown, tan, red, black, or even yellow. Freckles are formed when our skin is exposed to UVB radiation from the sun, activating melanocytes within our skin and increasing melanin production.

Freckles can occur anywhere on the body but are commonly seen on the face, arms, neck, back and chest. In most cases, freckles are harmless and generally fade with reduced sun exposure.

Age Spots: (or solar lentigo) are more distinct areas of pigmentation which are darker and defined. They are scattered in distribution compared to freckles and tend to arise years later in life – hence the name age spots. Age spots are caused by repeated sun exposure that leads to an over production of melanin and abnormal pigment retention.

Lentigines, also known as liver spots, typically appear on the back of the hands and on the face. They are flat light brown areas that don’t itch or scale.

Melasma: is a skin condition presenting as symmetric, dark, irregular shading over the cheeks, nose, upper lip, chin and forehead. Melasma is common in women, especially those who are pregnant or with a hormonal imbalance. It can affect all skin types but is more common in darker Fitzpatrick skin types. Melasma is caused when the melanocyte cells are stimulated by oestrogen and progesterone which encourages the skin to produce excessive melanin.

Post-Inflammatory Hyperpigmentation: (PIH) is a type of hyper pigment that occurs following inflammation or an injury to the skin. PIH is common after acne, trauma and inflammatory conditions. Severe inflammation or trauma can disrupt the bottom layer of the epidermis causing the melanocytes to produce melanin that can leak down into and become trapped in the deeper layers of your skin. This results in pigmentation that is deeper and more resistant to treatment.
