It's not exactly the same, but I recently tried biogel here in Toronto. I think it's the same idea -- they just paint a clear gel over your real nails to keep them stronger, and the gel sets with a UV light. After 3 weeks, you need to get them filled at the bottom. I just went for my first fill and also got the french manicure -- I'm very happy with it! The white gel is also painted on and set with the UV light so it will not chip or fade.
The first appointment cost about $60 CND because I also got a manicure and polish, but then the refill with the french manicure only cost $35. I went to Planet Nails at Yonge & Eglinton, if anyone is interested.
I hate the feel of acrylic nails, so I think this is a great option for the wedding. I might try to keep them a little longer for the next fill.
