Baby oil is a mineral oil-based product commonly used for moisturizing and soothing the skin. It is often applied to infants to help prevent dryness and keep their skin soft. The oil is typically fragrance-free and hypoallergenic, making it suitable for sensitive skin. In addition to its use on babies, baby oil can also be used by adults for various purposes, such as a massage oil or a makeup remover. It is important to note that while baby oil is safe for external use, it should not be ingested or applied to broken skin.
