It is NOT illegal for anybody to do a Botox or other skin procedure on _themselves._ Is it WISE for an uncertified person who hasn't done any research & doesn't know what they're doing to do it, NO. Some things are equal to a layman performing surgery on themselves - not smart. It's also NOT illegal (nor black market) to buy your own products, but it is wise to make sure they're GOOD/legit products from a reliable source.
