What kind of school do you go to for collagen or botox injections?

I understand that only doctors can administer botox, what about collagen? Are there any other plastic surgery type jobs that dont require so much education? Im very interested in the beauty industry, but not interested in going to cosmetology school for hair or nails. Thanks
