We cannot guarantee that every oil or bracelet is suitable for sensitive skin. Oil formulas, dilution, applicators, bead finishes, cords, adhesives and metal fittings can differ by product. Check the item page for its intended use and disclosed ingredients or materials; do not apply an oil that is not labeled for skin use. A small patch test may reduce uncertainty but cannot rule out irritation or allergy. Stop use if irritation occurs, and seek appropriate professional guidance if you have a known allergy or skin condition. Contact us with the exact product and option if a required material is not listed.
