petrolatum is a petroleum product that has been used for years as a skincare ingredient. It is known for its ability to lock in moisture and create a barrier on the skin, which can help to protect it from environmental damage. However, there is some concern about the safety of petrolatum, as it is a petroleum product and can be contaminated with harmful chemicals. There is also concern that it can clog pores and lead to breakouts. However, petrolatum is considered safe for most people to use on their face, and it is widely available in skincare products.
