Adverse skin reactions, including redness, itching, or burning sensations, are uncommon but can occur, particularly in individuals with sensitive skin. Allergic contact dermatitis is a documented possibility, therefore a preliminary patch test is recommended. Due to a lack of specific data regarding topical use during pregnancy or breastfeeding, professional medical consultation is advised. The EWG Skin Deep database notes moderate concern for allergies and immunotoxicity, with low concern for other toxicological endpoints.
