The med-spa side of the business demands perfection from its master injectors. In addition to using needles, these highly trained professionals wield cannulas for administering facial fillers, which—though generally more expensive and demanding of skill—reduce the likelihood of bruising and are safer. Similarly, cosmos ensures quality hair services with rigorous training for its stylists. No matter how much experience these cosmetologists gain after receiving their license, all cosmetologists joining Cosmos must spend at least three months as an apprentice, learning the demanding standards of the salon from basic blowouts to cutting-edge techniques while being mentored by the creative director.
