What's the best way for an RN nurse to start in aesthetics/spa work?

I'm an RN, and I don't know if I should do the training first (botox/laser/collagen, etc.) , or how well that's respected, or if there's some other way into the business. I'm also a male, which may be a handicap, and I'm not young (I'm 42), though I am not in bad shape (I know that industry is all about appearance).
BTW, I already have 13 years of experience as an RN, in ICU/Tele and then homecare.
