Subject: Why the special smell of your skin after tanning in a sun-parlor?

When tanning in a sun-parlor (without the use of any lotions 
or other scented products)your skin gets a very special 
smell/scent it doesn´t get when tanning in the real sun. (Or 
maybe it is only hidden behind other smells then?) It smells a 
bit "clinical and oxidised", difficult to describe, but 
something must have happened to your skin as the smell is so 
strong it can be felt through whatever soap or lotion you use 
afterwards. What does this smell/scent arise from?
