I would say over filing.It only needs a light buff and anyway there are many threads on here that state that done properly it is fine to remove shine and will not damage nails most other systems all require that anyway.
They look dehydrated but thats the acetone or remover ,and if you are not putting the gel back on and then oil them they are fine after an hour or so. Also as with other systems a client needs to oil their nails and look after them so they will grow healthy underneath and keep the free edge nice and flexible.
In removal especially in salons where they can be back to back with clients I think sometimes people get impatient with getting them off and scrape and file, when if left it will really just fall off often in one or two pieces.
Also if they are infilled they get thick and it is often kinder to soak off quickly rather than infilling.
Bio sculpture,calgel and other soak off gels have been really knocked on here in the past for being soak offs because many said it was bad to have nails in acetone for so long when more often or not it would be for about 15 mins every 4 weeks or more, unlike shellac which is every two, but suddenly it is alright to do so, maybe it isnt and people who have lovely natural nails who used to have manicures and polish will now find their nails breaking after a while.
Generally with bio and calgel etc people have it because they need the strength and cannot grow their own nails at all.
They also do not want to have to come every two weeks so i dont see how the new gel polishes are a replacement for people who usually have soak off gels.They are a seperate thing all together.
