Common, harmless changes
- Melasma ("the mask of pregnancy"): brown patches on the cheeks, forehead and upper lip. Sun protection is the best prevention.
- Linea nigra: a dark line down the middle of the abdomen that usually fades after birth
- Stretch marks: pink, purple or silvery streaks on the belly, breasts and thighs. They fade over time.
- Acne: hormone changes can cause breakouts. Many acne medicines are not safe in pregnancy, so check with your doctor before using any.
- Spider veins and varicose veins from increased blood volume
- Skin tags, which often appear in skin folds
Pregnancy-related rashes
- PUPPP (polymorphic eruption of pregnancy): very itchy red bumps and patches that often start in stretch marks late in pregnancy. It is uncomfortable but not harmful to the baby.
- Atopic eruption of pregnancy: eczema-like itchy patches, often in people with a history of eczema
- Pemphigoid gestationis: a rare, blistering rash that needs prompt medical care
Call your obstetrician right away if you have intense itching, especially on the palms and soles, without a rash. This can be a sign of intrahepatic cholestasis of pregnancy, a liver condition that needs monitoring.
Caring for your skin while pregnant
- Use a broad-spectrum sunscreen daily to limit melasma
- Moisturize often with a gentle, fragrance-free cream
- Check every skin product and medicine with your doctor, since some, such as retinoids, should be avoided
- See a dermatologist for any new or changing mole
