What is the difference between the Designer Skin Tanning Lines?

I%26#039;d like to know if anyone knows the difference between Designer Skin%26#039;s %26quot;Bronzing Ambiance%26quot; line (Whisper, Anarchy, etc...the vertically tall bottles), and it%26#039;s regular line (Bombshell, 14 Karat Gold, etc).





Common sense would be that the broning line has bronzers, but so does the other lines. any help would be appreciated.|||I used to own a tanning salon and the only difference I found with the lines is that the more expensive ones have more anti aging products in them. I used them a lot and of course the more expensive ones worked better.
