Pigmentation during menopause: what to know

Menopause-related changes in oestrogen can alter how pigment is produced and distributed. Some people notice facial brown patches, sometimes called melasma, while others see darker areas where skin has been rubbed or inflamed. Sunlight can deepen existing pigmentation, so a patch may become more noticeable even when the hormonal transition is the background factor.

Pigmentation is not a reliable way to diagnose menopause, and not every dark mark is hormone-related. Acne, eczema, hair removal, allergic reactions, medicines and ordinary sun exposure can also leave darker areas. Pigment changes usually do not cause pain, but their appearance and pattern matter when deciding whether they need review.

Use broad-spectrum sunscreen on exposed skin, reapply as directed on the product, and add shade, a hat or clothing when outdoors. Choose gentle, fragrance-free skin care and avoid scrubbing or picking at patches, because irritation can make darkening last longer.

Take a clear photograph in good light if you want to track a patch, keeping the date with the image. A clinician can check whether the pattern fits melasma or another cause and discuss suitable options, such as a prescribed cream or a procedure. Do not use unlabelled lightening products, especially those that may contain potent steroids or unsafe bleaching ingredients.

Arrange a medical review for a mark that is new and changing in size, shape or colour, has an uneven border, develops several colours, repeatedly bleeds, crusts, itches persistently or does not heal. Seek advice sooner if pigmentation appears suddenly across large areas, affects the eyes or mouth, or comes with other new symptoms.

A general clinician or dermatologist can examine the skin and decide whether testing is needed. Do not assume a changing mark is a menopause symptom simply because it appeared during the same period.

Ask what type of pigmentation the pattern suggests, whether any medicine or skin product could be contributing, and which treatments are appropriate for your skin tone. You can also ask how long to try a treatment, how to protect the area from sunlight, and which changes should prompt another appointment.
