Other forms: suntans
A suntan is the brown colour skin turns after days outdoors. Melanin, produced as a defence.
That is the uncomfortable fact about it, since tanning is the skin responding to damage, and there is no such thing as a safe one. Fashion reversed entirely on this within a century, since pale skin signalled wealth when the poor worked outdoors and a tan signalled leisure once they worked in factories. Sunburn is the painful version and a fake tan avoids the sun altogether.
