So i just bought Zoya's Utopia collection off of eBay. The colors are so gorgeous, so i'm thrilled to try them out. However, i only own a Sally Hansen base/top coat combo. I checked the ingredients and it contains the 'big 3': toluene, dibutyl phthalate and formaldehyde. I read somewhere that big-3-free nail polishes don't work well with base/top coats that have those chemicals in them.. Is this true? If so, can anyone recommend a good big-3-free base/top coat? Zoya's set was just a bit too expensive for me to invest in.. Thanks!
