Necessary to apply glycerin when using RF device?

[cuh4cuh]

Hello bhais, I've seen many people who use RF online apply glycerine to their face before using RF device, but is it mandatory? What happens if you don't apply glycerin?

Also, if any of you use RF device, PM me please saar.

Idk tbh. Might have to look into it. I’m getting the device for Christmas so I’ll know before then
