So lets try this... how about making those expensive serums last a little longer? Try using the nano chip tip with just a little of your favorite skin serum. (you know ... then one that you used almost every last drop... but its a little pricey... so you've hesitated to order more).... Yes that bottle. Apply over area, then turn on the iLLUMA with nano head attached and run over the area up to 3 times. Instant stimulation and gratification... and a feel good "me time" that also feels good to your "skin budget".
