It depends: some products can be safe while others may harm you. When you are breastfeeding or grand, the company recommends that you should not use their Hand Treatment and Body Cream.
The Cream is categorized as safe to use when you are pregnant. But keep in mind that it features Retinyl Palmitate; however, this ingredient is included in the product at a safe level for anyone pregnant or breastfeeding. The Face Oil features a small amount of Licorice Oil, an ingredient that is classified as safe to use during pregnancy.
We recommend you visit the brand's website and read the instructions for each product you want to purchase and be able to identify which is suitable and which one is not. Be sure to visit a physician before applying any products while pregnant.
