Masking Monday - Heated Mask Sheets

Hi guys, quick question. I know that cooling mask sheets has been the latest craze, but have you heard of heating mask sheets before use? Not sure if it's a Myth or Fact but placing the entire package in lukewarm water or rubbing between palms before use, heats up the mask. Once applied the heated mask increases blood circulation and ultimately promotes uptake of nutrients within the active ingredients. Has anyone ever tried heated mask sheets before? Please do let me know if this works!
