I'm a young male looking for a professional clinic in London to treat me with laser for all over my body. Olive skin & dark hair

Hi i'm a young male looking to get laser treatment all over most of my body, I need some help with finding somewhere to go & what laser is best for me. I have olive skin & dark hair, but after reading things on the internet I'm worried about who is going to laser me because of the risks I've heard of & I can't seem to find many professional clinics in London. I would be so thankful for some help in finding me a place that isn't risky but safe & worth the money, with the best laser for me, Thanks
