I use it once a month, and people comment on how white my teeth are the very next day! The box will last you four months

The instructions say not to use it more than once a day. It is probably because the lights may harm your eyes more than they would harm your skin though. Using once daily in the am worked over the course of a week with noticeable improvement seen in two days for us.

I like the 14% Day White better than the Night White, because I don't like sleeping with bleaching trays in my mouth. I get good whitening from the Day White formula. I use it twice a day and leave it on my teeth for 30 minutes, each time.

I'm slow on understanding the question, but when using the product it should be no longer than 10 min at a time. I don't know if that's for your skin safety or the machine.

3-4 hours is what I would recommend. Also keeping it covered in plastic and warm. Sit in the sun or warm with a dryer or warm towels periodically. Speeds the process and helps promote richer color

I want to add that I do it for about 4 to 5 days. For best results, use it right after a dental cleaning. Once your teeth get whitened, you can use it only periodically when you feel it is necessary or again after your next dental cleaning. Hope that helps.

Hi Dana.This is all gonna depend on how your teeth react to whitener and how many shades you want to whiten. I usually use 1 pack per 2 weeks. Now that is 14 days straight of whitening because I want the "Hollywood" white smile. Then I can go 4 months before I "Touch-Up" with 1 tube for a few days. I would recommend one pack and see how your teeth react first. Also keep in mind the % this made my teeth so sensitive I could only handle 1 day of whitening at a time. If you have never used the whitening before I might recommend a 20 or 25% instead of 35%

I leave it on one hour but I'm doing touch up only, not original whitening. My original was done in the dentist office. I now touch up after each time I get my teeth cleaned. There is an instruction sheet with the package.

I use for about 1 minute. You do not need to use it every day. Only when you need it, such as before a makeup since the effect is instantaneous.

I use it overnight on the 30 seconds on and 30 seconds off cycle. I can go 2 nights before having to refill.

I usually use it after I cleansed my face w/ hypoallergenic facial creme. Make sure that you wipe w/ alcohol before and after use. There's no instruction on the frequency of the use, but w/ me, when I have a zit, I use it almost every night and its really effective.

For me the effects last 4 to 6 hours depending on activity factors. Unless you over-apply there shouldn't be any visible residue to flake off.

Every other day for the first week. Once my skin is used to it, I use it once a week as a peel, leaving it on for five minutes then rinsing off then applying a new ght creme. Hope this info helps.

Depending on the amount used. Need only a small amount on scalp at night time

It's about the same as applying the original several days in a row. Not a huge difference.....I'd recommend either, unless you're really pale.

I used to apply them at night only for a few minutes (half an hour max.); only slept with them on a couple of times or so. I noticed a slight increased effect by leaving them overnight,though. For a while, I was using them every night, then- not as often, which reminds me to go back to using them, because in my case they were very effective at smoothing wrinkles, especially my laugh lines. Hope it helps. Good luck!

I usually brush them half an hour/one hour before using the white strips to prevent sensibility.
