Review title is Unpleasant smell [SEP] I purchased this gel to use with my solawave device. The cost per ounce was very reasonable. I opened it and I was put off by the unpleasant smell. I don’t know if I got a spoiled batch or that’s the way it smells. Conductive gel is a must if you are using any kind of a facial device.<br />The Nuface gel works well and doesn’t have an unpleasant smell.
