It is generally safe to use Pears baby lotion on your skin during pregnancy, including at 20 weeks and 6 days. However, it is important to check the ingredients list for any potential allergens or irritants that may not be suitable for your specific needs. If you have any concerns or known allergies, it is recommended to consult with your healthcare provider before using any new skincare products. Additionally, it's always a good idea to do a patch test on a small area of your skin before applying the lotion all over your body. This will help ensure that you don't experience any adverse reactions. Overall, Pears baby lotion is designed for delicate baby skin and can provide gentle moisturization for pregnant women as well.
