Its perfectly right. That would be the normal amount of time for for a SOG enhancement (or a L&P enhancement) which is a 3 week service not a fortnightly service and perfectly acceptable as it always has been for clients for the last 20 years. Now with the new CND Nourishing Remover it is even more acceptable.
CND always quote the longest scenario though, to account for different thicknesses of product as people vary. We all know that for most of us Shellac soaks off in less than 10 minutes but 10 is what they quote.
With Brisa Lite Sculpting gel you are moving into the enhancement category of nails ... It's different to UV colour coats. Full service Nail technicians will understand it very well.
I am actually enhancement trained so I do understand. I havent heard of 30 minutes being normal to remove soak off gel. I have used young nails maniQ system with full set of extensions and it has taken 20mins tops
How long is removal for the smoothing gel?
