Ikon.iQ all the way for me!
Think of it this way, if you are going to handle a product on a daily basis wouldn’t you want it to be one least likely to damage your health?
It’s alarming to see how many companies are popping up that have really polished marketing but actually just buy in their products from Chinese wholesalers and have different branded packaging.
Be aware that in China there are zero safety regulations on Gel ingredients and the risk of you, or one of your clients, developing an allergy are increased dramatically. The highest incidence of allergy has been seen in the DIY market... using gels from Amazon, eBay etc. They all come from China.
Now that ‘pro’ brands are being presented that come from the same place, the logic is that there is going to be an increase in reactions seen in trained nail techs. The wholesalers are also adept at providing misleading mSDS data to hide the high HEMA content in particular so it’s a real mine field.
Until this state of affairs changes I would restrict your choices to products manufactured in the USA or EU where exacting regulatory safety criteria must be met. If you invest a fortune in training and setting up a business, it’s a good plan these days, to do a bit of research to ensure you will be able to operate long enough to reap the rewards rather than end up being allergic to your stock in trade.
