Is It Okay To Use Castile Soap On Your Body?

Castile soap is a natural, vegetable-based soap used for both personal hygiene and household cleaning. Originating from the Mediterranean, Castile soap got its name from the Castile region in Spain (via Healthline). Although the soap was originally made from pure olive oil, it can also be made with various other plant-based oils, including coconut, hemp, castor, and avocado oils. 

Known for its versatility, Castile soap is a multi-purpose soap that can be used for many different types of cleaning and is generally safe to use as long as it's diluted properly, according to Healthline. For household purposes, it can be used as dish soap, detergent, window cleaner, and toilet cleaner. And when it comes to personal hygiene, Castile soap can be used as a shampoo, facial cleanser, body wash, makeup remover, hand soap, and shaving cream. Research has shown that it can also heal minor wounds and clean open fractures. But is this versatile soap safe for all skin types?

Castile soap's effect on sensitive skin

As a natural cleanser and moisturizer, Castile soap can be a great addition to your hair and skincare routine. According to experts at Byrdie, Castile soap's natural and environmentally friendly formula is safe and effective for most skin types. In addition to being vegan and free of harsh chemicals, Castile soap can effectively cleanse, soften, and moisturize your body.

However, for some people with sensitive skin, Castile soap may not be a suitable fit. "Castile soap is alkaline and not perfectly pH balanced, so those with sensitive skin or compromised skin barriers may do better with a different cleanser," Blair Murphy-Rose, board-certified dermatologist, told Byrdie. "Still, it is often okay for sensitive skin," she explains. You may also want to steer clear of the soap if you're allergic to lye and essential oils, which tend to be highly concentrated in Castile soap. If your skin develops a reaction shortly after using it, Castile soap might not be the right soap for you.
