Hormone-Related Pigmentation

Hormone-Related Pigmentation — darkened patches of skin driven by hormonal shifts that stimulate melanin-producing cells, most commonly seen as melasma. It often appears as symmetrical brown or gray-brown patches on the cheeks, forehead, and upper lip, and can be triggered by pregnancy, oral contraceptives, or hormone therapy.

Key points

  • Hormonal changes can increase the activity of melanocytes, the cells that produce pigment, leading to patchy darkening known as melasma.
  • Common triggers include pregnancy, birth control pills, and hormone therapy, often combined with sun exposure.
  • UV and visible light strongly worsen this pigmentation, so broad-spectrum sunscreen, ideally with tint for visible-light protection, is a cornerstone of care.
  • It can be stubborn and prone to recurrence, so management focuses on sun protection, gentle brightening ingredients, and professional guidance.

Frequently asked

What is melasma and why is it linked to hormones?

Melasma is patchy facial darkening caused by overactive pigment cells, and hormonal changes from pregnancy or certain medications can stimulate that pigment production.

Can hormonal pigmentation be fully removed?

It can often be lightened with sun protection and brightening ingredients, but it is prone to returning, so ongoing care and professional advice are usually needed.
