Hyperpigmentation is the discolouration of skin caused by internal physical factors and/or external factors which can include hormonal changes, sun exposure, skin type, trauma and the skin’s natural ageing process.
Presenting as areas of uneven skin tone, darkness, age spots or freckles, pigmentation occurs when excess melanin (skin pigment) has been stimulated. Surface pigmentation (Epidermal or Superficial) usually affects lighter skin tones and is usually created by sun damage, for example; Sun spots, Age spots, Freckles.
