While pregnant and breastfeeding, there are certain ingredients to keep an eye out for.
It’s important to note that there’s limited scientific evidence for many topical treatments.1 As they haven’t been tested on pregnant people for ethical reasons, we can’t be completely sure they’re safe or not.1 That’s why only the mildest treatments are often recommended.2
Salicylic acid (BHA), found in many acne treatments and cleansers, may have harmful effects during pregnancy.1
Retinoids (for example
retinol, retinal, tretinoin and isotretinoin) are based on vitamin A. They’re used to even out skin tone and help with acne.
1 Retinoids have been linked to birth defects and should be avoided during pregnancy.
1 Risks for breastfeeding newborns have also been demonstrated with
tretinoin (a concentration of pure retinoic acid, which makes it stronger than retinol).
1 Bakuchiol, a plant-based alternative to retinol, is generally considered a more gentle option that could be used in pregnancy – however, it’s best to check with your doctor or a dermatologist first.
Hydroquinone is used to treat hyperpigmentation.1 Avoid it during both pregnancy and breastfeeding, as it has high systemic absorption and can be passed onto your baby.1
Parabens (for example, methylparaben, propylparaben, butylparaben and ethylparaben) are used as preservatives in skincare products and have been linked to various effects, including impacts on birth weight and maternal blood pressure.14,15
Some
chemical sunscreens are absorbed through the skin and have been found in the bloodstream. Instead, choose physical (mineral)
sunscreens containing zinc oxide or titanium dioxide, which provide sun protection.
1 Finally, some
essential oils, like rosemary, clary sage or jasmine, may induce uterine contractions – though evidence either way is limited.
16,17 It’s best to err on the side of caution and speak to your doctor before having a massage with essential oils. The NHS suggests that direct contact with essential oils should be avoided in the first trimester.
