Under 18s in Scotland are now officially banned from using sunbeds because of fears they can cause cancer.
New laws brought in on Tuesday, also ban coin operated tanning salons because if there aren't any staff there, no-one can check your age.
Earlier this year a cancer charity warned that using sunbeds could increase the risk of getting cancer.
Campaigners reckon more than 100 UK deaths from skin cancer could be linked to the use of sunbeds.
And they want the new Scottish laws to be introduced in the rest of the UK too.
In July, the International Agency for Research on Cancer (IARC) said people younger than 30 who use sunbeds are more likely to get cancer than those who don't.
The Sunbed Association disagreed - at the time it said there was "no proven link" using sunbeds responsibly can cause cancer.
