Efectivo para la higiene

Does a good job and very easy to use

I bought this in March 2021. Just cracked it open in Nov 2023. It works. The photo is after only 3 treatments! Lightened 2 levels. My teeth are a little sensitive so I know it's working, ugh!

Bought 3 of these as a stocking stuffer. The boys use them bc who doesn’t want nice white teeth!

First of all, I had an issue with the pens leaking upon arrival like a couple of other reviews had mentioned. It happens. During registration, I was contacted by a real person who wanted to resolve my issue, no questions asked.I've been using the kit for a few days now. I have used other kits before, and had relatively good results. The difference is in this kit, you don't need to use trays. The brush pens work really well getting the gel between the base areas of the teeth where it seems harder to lighten. There is less product to use as it doesn't have to squish all over, and less time per sitting.There is little to no irritation. I was able to use this kit 2x/day for the past 3 days and I am really seeing a difference. After the second application, my lips may have been a little dry, as if I've sucked on a lemon or something, but it goes away within an hour. Gums and teeth don't ache or become sensitive like other gels I have used. The light is a better design than others as well - being powered separately. With others I have had, it is a battery, and while not heavy, having something hanging out of the front of your mouth vs a wire- it really is more comfortable, and a brighter light (I can only imagine that helps with the results).I am using this while also doing Invisalign. I have cemented nibs on my teeth for the trays that stain super easily and dark. This kit has definitely won me over. I could do this every day.
