Brill thank you!I'm using the nuface branded one because it came with the device but I wash it off straight after so I do not plan on replacing it when I'm out! I've just ordered this to try: Amazon product but any ultrasound gel should allow the microcurrent to get through (and loads of people say normal aloe vera gel works too but I'd rather be sure it's working)
edit: I don't think my amazon link has worked. it's anagel ultrasound gel, £3.95 for 250ml
