In pregnancy, products from Nivea, Burt’s Bees, and Mustela are usually considered safe when they are basic skin care items used as directed, but safety depends more on the ingredient list than on the brand name. Based on the source provided, there is not enough evidence to say that one of these brands is clearly safer than the others.
The main point is to avoid products with ingredients that are more concerning in pregnancy, especially retinoids and hydroquinone. Most over-the-counter moisturizers and gentle skin care products have low absorption through the skin, which makes them less likely to pose a problem during pregnancy.
Mustela is described in the source as a brand that avoids certain ingredients, including some substances linked to endocrine concerns, but that does not prove it is safer than Nivea or Burt’s Bees overall. The source material also does not include a direct review of Burt’s Bees products, so a full brand-to-brand comparison cannot be made with confidence.
The safest choice is to prefer simple, fragrance-light products and check the label before using anything regularly during pregnancy. An obstetrician or dermatologist is the best specialist to review a specific product, and self-medicating with acne or skin-lightening treatments should be avoided.
