Alternative to Nuface primer gel?

[Uptonogoodtoo]

Anybody recommend a gel when using the nuface toner? The gel they use is to expensive. I’ve tried Aloe Vera from H & B but my skin doesn’t seem to like it.
Any suggestions? Does collagen gel work with the device?

Yes I’ve used collagen gel before and it was fine.

I bought some medical ultrasound gel from amazon - huge tub for not much!

I also use a big pump dispenser of ultrasound gel from Amazon. Has worked perfectly well. I just chose one with good reviews.
