Sunless Tanning Certification

Hi Everyone!

My names Alyson, I am starting to open a new sunless tanning business. I have tanned clients in the past and stopped offering spray tans because I wanted to go to college for computers
Anyways, I have some free time again and am starting things back up. In the past I got certified with Norvell and took all the classes they offered. That was a couple of years ago so I am going through Aviva Labs to get certified now.
I was just wondering if any of the certifications that are recieved after taking the sunless course hold more value or weight in the industry. Or is it just a matter of personal preference? I feel like all the courses would have the same fundamental information with a different type of spraying technique no matter where one recieve the certification.

Does anyone have any suggestions or ideas on what are considered the best rated places to get a sunless tanning certification please?


Thanks

Alyson
