What kind of rays cause a suntan?

I,don't tan I,burn do not go into the sun.

we are bombed by GAMA RAYS EVERY SECOND . the rays pass through the Earth by our STAR CALLED THE SUN.

I love sun bathing!!! in the nice sun!! and it's like 80 degrees!! ahh no shade!! it's nice!!

i love 💕 my ⛅ tan

As we know in Australia it doesn't so much give you "a suntan" as it gives you skin cancer and the nightmare sunburn known as "hell's itch" 😱
