Hyperpigmentation occurs when excess melanin causes a darkened appearance to the skin in either small or large areas. Pigmentation is the natural colour of a person’s skin and it is related to melanin production. Melanin protects skin cells and their DNA by absorbing the sun’s ultraviolet rays. Darker skin types, in general, are more susceptible to hyperpigmentation than lighter skin types because their skin naturally contains more melanin.
Hyperpigmentation Types and Triggers:
UV induced: This type of hyperpigmentation shows in the form of freckles, age spots and uneven skin tone. It is caused by exposure to ultraviolet rays, whether from the sun or tanning beds.
Post-Inflammatory Hyperpigmentation: This is found in areas of the skin that have been subjected to inflammation due to trauma, acne or irritation (eg. fragrances or laser side effects). Inflammation stimulates Langerhans cells (immune cells), which alter the activity of melanocytes (skin cells), causing increased pigment production.
Melasma (chloasma): Melasma appears as symmetrical patches most often on the cheeks, chin, upper lip and forehead. It can be related to pregnancy, birth control pill, menopause or hormone replacement therapy.
