I have just purchased the Brisa Gel intro pack and am waiting for my conversion course. I have read everyones rave reviews on Brisa and it happens to be available at a local supplier making it a lot more convenient to purchase. I have watched the video, however, I still have a few questions. First, when my clients come in for a rebalance, do you recommend removal of the current gel on their nails or can Brisa be applied overtop of the existing gel? Second, it doesn't say in the video about colored smile lines. Do you have to trench in a new smile line and completely remove the gel at the smile line and free edge or can the free edge just be thinned down? Third, I am assuming the paint on white is applied after the rebalance and the nails are shaped and filed. Apply paint on white, cure, and top gloss. Is this incorrect? Does there need to be an inhibition layer on the nails before the paint on white? Any and all advice is appreciated.
