Sensitivity level is different in every person so it’s difficult to say exactly what is causing your reaction. We recommend a conservative approach to skincare – less is more – so you may want to discontinue use of the product for a few days and then try again. If you still experience discomfort, we have a 100% Customer Satisfaction Guarantee – if you are not completely and unconditionally satisfied with the product simply return the unused portion to us referencing your order number and we will issue you a full refund. If you need to return the product please reference our website for returns procedures.
