Sun Protection and Pigmentation During Pregnancy

During pregnancy, increased estrogen and progesterone can increase melanin production and this can lead to skin discoloration. Melasma (pregnancy mask) can appear as brown spots on the face — especially on the forehead, cheeks, and upper lip area. A degree of hyperpigmentation can develop in a significant proportion of pregnant women.

Sun protection is very important: Sunlight can make spots more prominent. Using broad-spectrum SPF 30+ sunscreen daily — even on cloudy days — is a good habit. Physical (mineral) sunscreens (zinc oxide, titanium dioxide) are considered safer during pregnancy than chemical filters.

Additional protection: Wide-brimmed hats, sunglasses, and staying in the shade can help reduce spots. Avoiding excessive direct sun exposure between 10:00 AM and 4:00 PM may be wise. Vitamin C serum and niacinamide (B3) can help lighten spots and are considered safe during pregnancy.

After birth: Melasma usually fades on its own 6-12 months after birth. If it doesn't fade, consulting your dermatologist is best — options can be evaluated.
