I use shellac and biosculpture and shellac is the easiest to remove by far.
Just to stir up a hornets nest here, I know we keep getting told that Shellac isnt a gel polish, it's a power polish, but I disagree. Power polish isnt a technical term, but gel polish is. What is the definition of a gel? It's an acrylate product that contains monomers and polymers which cure under the UV light. Shellac does indeed contain acrylates and cures under a UV light so unless someone can provide me with a technical reason why shellac is not an acrylate product containing monomers/polymers I would have to disagree and argue that it is reasonable to describe shellac as a gel polish, or in the very least an acrylate based hybrid polish. CND were describing shellac as a hybrid polish when it first came out and before they coined the term power polish and I was much more comfortable with that term. Power polish doesnt really say much about the product in my opinion.
Go on then, feel free to shoot me down in flames and tell me I'm wrong!! On a serious note though I'm really not trying to kick up trouble so please dont take what I've said the wrong way, this is by no means a sleight on shellac or CND or S2 I have nothing but respect for the product and the companies, and if anyone can give me further information to disprove my theory I'm quite open minded about the subject and would be happy to be proved wrong if there's further info out there :green:
