Use twice weekly at nighttime only. If used as part of a NIOD regimen, apply CAIS/MMHC first and then apply a thin layer of this masque over the entire face, avoiding direct eye contact. Outside of a NIOD regimen, apply over lighter serums and avoid application of thicker cream formulations. Massage for about 20-40 seconds. Do not apply other products over VM. Do not rinse off until the AM. VM is not recommended for very oily skin types and should not be applied on peeling or irritated skin. If irritation occurs, cease use and consult a physician. Use only as directed on unbroken skin. Patch testing prior to use is advised. Refer to our in-depth guide to patch testing. Keep out of reach of children.
