I also use BioSculpture, and am very happy, as said before - not quite as strong as l&p, butI have found it's more flexible and some clients prefer this.. Although I use l&p as well, i prefer working with biosculpture gel and all my clients are happy. :biggrin:
I also find my rep (Ilona) really helpful, as she's always on the end of the phone if you have any little niggles or probs - which is dead handy.
I've not used any other gels (other than a 'playday' with star nails gel - which I found much harder to work with and required and lot of buffing etc - the end result was not far off l&p. i thin this is the difference between 'european' and 'american' gels - or at least that's what the star nails trainer said.
Biosculpture needs no buffing, as it is very self-levelling - and cures to a high gloss finish, just a wipe and top coat for protection.
Hope this helps - I'm pretty new to it all so I don't have a lot to compare it to, but if I can get on with it anyone can! It is pretty expensive - but to be honest, all the 'better' products are - at least you can charge a premium knowing the product won't let you down!
