If you are prone to adverse reactions from certain ingredients it can be a good idea to do a small patch test before using our products. Even though we use gentle, botanically derived ingredients, there is still the potential for sensitivity. Simply rub a small amount of the Cream on an unaffected area of the skin, either on the inside of the elbow or on the nape of the neck. If the tested area becomes red or irritated within the next 24 hours it is best to avoid the use of the product(s) in question. If you are sensitive to a particular ingredient and are unsure about our formula, please feel free to get in touch with us directly. We are more than happy to help in any way we can.
