The Faze Gel system is a 2 gel system..............
Faze is a simple one step gel......... offering you Faze2 as the finishing gel....mostly used to seal in Airbrushed art......
Flexible and not bad to use........
Brisa is Liquid and Powder Technology in Gel form..........Retention+ Technology
You use a thin brush on bonder, a builder in clear or pink, a sculpting white gel, a paint on white gel and a finishing Gel..........
You are a bit limited with Faze as sculpting is not as good with this gel as it is with Brisa... well I never managed it as well as I do with the Brisa gel....
So Brisa is the best in my book
