This gel spreads on the skin super easy and provides appropriate slip throughout my whole session (maybe that's why it feel little sticky to the touch). Unlike any conductive gels this one has so so many extra beneficial ingredients for the skin. I actually don't wash it off and keep it as an overnight mask as well.
The bottle lasts me about 3.5 months as I treat my skin almost everyday, using 4 -5 pumps each time, depending on my skin condition and ambient humidity (less in the summer). It has no fragrance whatsoever, so I'd assume it is user-friendly, even the sensitive ones or with hyper sense of smell. I highly recommend it as one of my favorite skim products.
