Depending on how conservative your ob/gyn is regarding ingredients like essential oils and willow bark extract, you might get different answers from different practitioners. This also depends on your body, your personal sensitivity to these ingredients, what risks are present or absent with the pregnancy, etc.
The truth is, little to no studies have been done in vivo since no woman wants to potentially endanger her baby for the sake of science.
moss’s founder Celestyna Higgins personally used all the moss products during her pregnancy (healthy full term baby) but if you have any doubts, it is advised to consult your doctor.
Please also note, the body goes through drastic hormonal changes during pregnancy and this manifests in different ways for different skins. Whether or not you use moss during pregnancy, be prepared for your skincare needs changing (often multiple times) during your pregnancy as well as your tolerance/preference for textures and scents.
More important than skincare, what we recommend (if at all possible), is to enjoy lots of rest and “empty” time during the pregnancy, building up reserves of energy and love. Pregnancy can be likened to the chrysalis stage in the life cycle of a butterfly, so stillness and inviting change, preparing for chance are highly recommended.
