When it comes to wax melts, the safety during pregnancy largely depends on the ingredients used in the product. Generally speaking, wax melts that are made from natural ingredients such as soy or beeswax and scented with essential oils are considered safe. However, it is important to read the label and ensure that there are no potentially harmful chemicals or synthetic fragrances added to the wax melts. Pregnant individuals should also be cautious about any specific scents that they may have sensitivity to, as strong fragrances might trigger nausea or headaches during this time.
