We love sunbeds! They provide a fast and easy way to get a golden tan, no matter the weather or time of day. The body is of course exposed to heat, even if you tan for a short period of time. So, once your session is over you will feel the need to take a shower.
Although a shower seems like a good idea, you know, to refresh yourself. A shower after your session could impact your tan. The body doesn't cool down immediately. It takes some time. Something similar happens to the melanin in your skin.
Melanin is the pigment that gives colour to your skin which is stimulated by UV light, making the skin darker. The stimulation doesn't stop immediately after your tanning session. It's a process that keeps going even after you leave the tanning salon. If you shower straight away your going to minimise the effectiveness of your tan and that's the total opposite of what you want!
Bronzers and accelerators are made to speed up your tanning process. Having a shower will wash away every last drop of that solution without allowing it to work it's complete magic on your skin.
Sunbeds feel like a quick process, and it is, but your body keeps working after and you should it give it some time to tan. Give it atleast 2 hours before you decide to take a shower. You'll get more effective and longer lasting results that way.
