I am horrified (but sadly not shocked) that there are so called training providers training unqualified students to do dermaplaning!! It's no wonder people think they can take a short cut into the industry! Although the educators are primarily at fault here, students themselves have to take some responsibility too in researching before they enroll on these courses!
Insurance companies are happy to take your money, but will always try and look for a loophole not to pay out if there's a claim, so you really do need to read ALL the small print on their policies!
Insync aren't perfect either from what I've heard. They will only cover you whilst you are insured with them, so if you change insurance providers and then get a historical claim (which could happen), they won't honour it, even though you were insured with them when the treatment was carried out.
