Sometimes, these patches also appear on the neck, chest, forearms, and other body parts exposed to the sun (1).Maternal health is generally unaffected by the condition and poses no harm to the baby. Although the patches can be treated with topical medicines, they fade with time in most women.

Is It Normal To Have Melasma During Pregnancy?

According to a research paper published in the Croatian journal Collegium Antropologicum, melasma affects around 50% to 70% of pregnant women. The National Institutes of Health state that its prevalence fluctuates between 1.5% and 33%, contingent upon the population studied. The increased levels of estrogeniXA sex hormone responsible for the development of female sexual characteristics , progesterone, and the melanocyte-stimulating hormone (MSH) in the third trimester could trigger melasma (2). Melasma is not a painful condition and does not lead to any pregnancy complications. But what might cause it?

Causes Of Melasma During Pregnancy

  • The exact cause of melasma is unclear. It is likely to develop when the melanocytesiXCells that create the melanin pigments that give hair, eyes, and skin their color of the skin produce extra color. Those with darker complexion are likely to develop melasma as they have active melanocytes than those with a lighter complexion (3).

Some of the common melasma triggers include

  • Exposure to Ultraviolet light (UV rays) from the sun stimulates melanocytes, leading to melasma. The condition might worsen during summers (4).

  • Hormonal changes are another reason for pregnancy melasma. The symptoms of melasma are likely to be triggered in pregnant women during gestation by increased levels of hormones such as estrogen, progesterone, and MSH in the third trimester (5) (6).
  • Other factors include genetic history (if someone else in the family has been suffering from it), skincare products, drugs, multiple pregnancies, and older maternal age.

Melasma that occurs during pregnancy tends to go away after a few months postpartum when the hormonal activity stabilizes (7).

Certain medicines, such as anti-epileptic pills, some antibiotics, and blood pressure medicines, may also trigger melasma (11).

Ways To Reduce The Melasma Patches

Although melasma disappears with time, certain things might help in minimizing the flare-ups on your skin.

  • Stay out of the sun: The foremost step is to avoid sun exposure as much as possible, to prevent skin damage and the consequent skin discoloration. If your work forces you to go out in the sun, apply a broad-spectrum sunblock. Choose sunscreens or blocks with SPF 25 or higher that may help to prevent exacerbating chloasma (8). Also, wear a wide-brimmed hat, long-sleeved dress, and sunglasses, and avoid tanning salons.
  • Avoid skincare products or cosmetics: Facial cleansers, skin creams, and make-up products may irritate your skin, making melasma worse. Avoid them until you have given birth, or the melasma disappears.

  • Do not wax: Waxing for removing hair might worsen melasma as it could cause skin inflammation. The effect may be high, especially in the areas affected by hyperpigmentation (uneven skin tone).

Although no specific diet or prenatal vitamin can help prevent melasma. A well-balanced diet with adequate vitamin D may help keep the skin healthy.

Use dermatologist-recommended, fragrance-free, gentle skincare products to avoid irritating the skin or worsening the existing condition (12).

Can Pregnancy Melasma Be Treated?

Besides taking precautions to prevent flare-ups, you could talk to a dermatology expert about the treatment options to minimize the patches. However, the treatment options are limited for pregnant women.

  • Topical medications such as retinoids and hydroquinone are usually prescribed for melasma, but their safety during pregnancy is not studied (9).
  • Plant products with vitamin C, glycolic acid, arbutiniXA substance extracted from the bearberry plant that is considered to be a skin-lightening agent , azelaic acidiXA natural compound found in grains, rye, barley, and animal products and synthetically used to treat certain skin issues , licorice extractiXA flowering herb known for aiding digestive problems and infections , or soybean extract help protect the pregnancy glow. Again, you may only use them when their benefits outweigh their risks (8).
