When a product is contraindicated during pregnancy or breastfeeding, this information will be mentioned on the product page in the "Precautions for use" section. These are generally products containing essential oils, certain hydrolats or molecules such as retinol, which are not recommended during pregnancy.
If there is no mention of Precautions for use on the product page then there is no contraindications.
