Allergic Reaction.  Possible Fake [SEP] I have other IBD gel builders but this one caused an allergic reaction on my face (from filing dust and touching my face after nails were done).  I had this happen with an acrylic monomer a couple years back and found out the brand had ingredients in it that were band from most countries.  I don't know if that's the case here, but it gave me the same allergic reaction.  Not worth the risk.  The consistency was off compared to my other IBD's as well, it's not as smooth.  However, it did harden and the the color was a nice rosey nude.
