Most people with psoriasis find relief from their symptoms with a combination of traditional treatments, lifestyle changes, and natural at-home remedies, such as moisturizing oils. However, there’s not enough scientific research to prove that oils actually make a difference to psoriasis symptoms—so your dermatologist might not suggest that you stock up on oils for those itchy, flaky plaques.

“Oils are not an approved therapy for psoriasis, as there are no randomized studies evaluating their use,” warns board-certified dermatologist Rhonda Klein, M.D. of Modern Dermatology in Westport, Connecticut. “Thus, caution is advised.”

Still, many people who live with psoriasis do find relief from certain oils, so they may be worth a try. If you want to use them, ask your doctor first, as some oils aren’t recommended for people with certain health conditions or people who are pregnant or breastfeeding.
