Basically a tingle cream stimulates blood flow to the skin, which can help speed up the tanning process, there is a factor of how much tingle you will get from one of these creams so start low if you're going to. All I can say is you really might not like the sensation, it could be described as hot and itchy.
Accelerators have products in them which assist the body's production of melanin before and after UV exposure.
Bronzers are pretty much what they sound like, they kick start the tanning process with a little DHA for immediate colour.
I don't personally use sunbeds now, I have a few times in the past but noting major as I'm very pale and you have to understand the massive risks and for me it wasn't worth it - I'd much rather use a fake tan. They're not like they used to be and there are many that deliver very nice colour. I have used the lotions and stuff but it was usually outdoors when I was in the US. One of the purposes of tanning lotions is to moisturise, so I see no harm in using other moisturisers before and after using a bed.
In terms of going everyday, I don't think that is sensible at all, if you're going everyday you are at far greater risk of burning which means you can't then tan at all. Anyway the tanning process takes 48-72 hours so this eliminates the need to go that frequently and because of this if you didn't burn the first time doesn't mean at the next session you won't. Always tan in moderation if you must, try 3/4 times a week to build a base tan and then 1/2 times a week maintenance. I mean I don't mind answering the question but at the same time I really don't think sunbeds are the way to go, atleast with fake tan it's quick to apply, you can apply as much/little as you want and when, you get almost instant colour and all in all it's not harmful.
