What is melanin?

Melanin is the substance in skin which gives it its color.^II It is produced by cells called melanocytes. When these cells produce too much melanin, these clusters of pigmentation are released to other skin cells and can form skin discolorations, dark spots and hyperpigmentation.

What causes hyperpigmentation on skin?

What is post-inflammatory hyperpigmentation?

When skin becomes irritated or damaged, it attempts to protect itself which can trigger melanocytes to become overactive and produce excess melanin. Acne blemishes are a common form of skin irritation which cause post-inflammatory hyperpigmentation.

How does sun exposure cause hyperpigmentation?

Sun exposure is the leading cause of hyperpigmentation in fair-skinned individuals.^III Even if you do not notice sunburn or damage after being out in the sun, UV rays can still cause pigment changes. In addition to forming new dark spots and discolorations, sun exposure can also cause existing hyperpigmentation to darken and become even more visible.

How does pollution cause hyperpigmentation?

Pollution and free radicals can cause oxidative damage to the skin. As skin attempts to protect and defend itself from these external aggressors, melanocytes may overproduce melanin and form hyperpigmentation and discolorations.

Does hyperpigmentation go away on its own?

While some forms of hyperpigmentation are permanent, many types will fade over time.
