Tanning to Tighten Skin?

I was reading an article on T-Nation in which the author said that tanning seemed to assist in tightening the skin whether in the sun or the tanning bed. Is there any info on this? Anybody know if it works?

I don’t know scientifically whether it does, but i’m sure you’ve been sunburned before and noticed how tight your skin feels. Also I think a darker skin tone shows muscle definition better.

When they remove basal cell (pre-skin cancer) growths from your body, they make a football-shaped excision. After it is removed, they sew the two edges together and this tends to tighten the skin somewhat too.

tanning also makes you sweat which makes you lose salt and waterweight is decreased.
