How to Use
Apply a few drops to the face in the morning and evening. A tingling sensation can be expected after application. If the sensation is too strong, the formula can be mixed with other creams or serums of your preference before each application to reduce the strength. If irritation occurs, rinse off, cease use, and consult a physician. Use only as directed on unbroken skin. Patch testing prior to use is advised. Keep out of reach of children.
