It better not be. I think I would become a hermit without my 16% tan.
I'm no skin geek, but I know it would dramatically affect the industry if people who like a dark tan, or even darker skin clients who want the extra glow, can't get it professionally done. It will end up that more will be finding alternate ways such as tanning pills.
I often use sunbeds myself, but the ones who don't and can't get a dark tan will probably move to beds, and in their quest for a dark colour fast will over use them causing damage to their skin.
No doubt this has been imagined up by some pasty skinned ugly person who has no idea about the world of vanity, or understands that some just want to be very dark safely, x
