Top layer of gels peeling off?

[Zo3x]

Hi everyone just a quick question on why our top layers of gel would be peeling or cracking off? We use gel bottle builder gel in the pot, gel bottle gel polish and sometimes bio sculpture gel. TIA xo

I don't use TGB but I think if you use the search option there are a couple of posts about TGB top coat peeling, I think there is a specific one needed over certain products. It's not a one Top Coat works on all products in the range.
