Do you deliver the product with a cold pack? I understand the solution should keep cold?

Hello, the expertwhitening 16%CP is Carbamide peroxide (which is a stabilized form of hydrogen peroxide) that does not require a cold pack for shipping. Also, it does not require refrigeration at home. It can be stored at room temperature away from direct heat.

I already have the teeth trays that I got from my dentist, is this product safe for my trays for whitening?

Yes, this gel is specifically for tray whitening. This is the most gentle formula gel with amazing whitening results. You can wear this gel in your trays for one hour or overnight. Whiten for 7-10 days in succession (once a day) until you achieve your desired shafde of white - then only whiten (or touch up) as needed.

Is this product ok to use after brushing my teeth daily at night?

Yes. It works perfectly after you've brushed your teeth. You can wear it in your trays for 60 minutes or overnight. Whether you would wear the gel EVERY day without taking a break is not necessary. Your teeth will reach a certain shade of white and not whiten any more (the natural whitest base color of your natural teeth). After that you whiten (or touch up) as needed.

How long should I use this product on my teeth trays for?

I found the answer below on the web, and would add that you can keep increasing the time by 15 minutes if you don't experience much sensitivity:Wear gel in trays over teeth for recommended time (determined by the strength gel that you are using). 16% (60-minutes) / 22% (45-minutes) / 35% (30- minutes) and 44% (15-minutes).The website is http://expertwhitening.com/pages/directions-for-use
