Belli Pregnancy has set a higher standard for prenatal safety, as the only skin care line in the world that is teratology screened. Belli searches through over 16 million medical research articles in over 5000 international journals, and uses the information to exclude ingredients with even remote links to birth defects or other problems with pregnancy. Belli Motherhood is LactMed screened to avoid ingredients linked to harmful effects during breastfeeding. Belli Baby is screened for xenoestrogens—chemicals which can act like hormones that interfere with normal development of the reproductive system. So no matter which Belli products you use, you can have peace of mind erring on the side of caution.
