EUTHYMOL Teeth Whitening Strips Kit | Booster Gel+Strips (5 Count)

I sorta dropped the ball on using them consecutive days in a row but they still worked well for me. Using the comparison strip, I think I improved by around 4 shades. It's only hard to tell because my teeth were at the yellowest shade, and some of the ones in the middle look really similar. The booster isn't spicy and the sensitivity afterwards isn't extreme. It will be a little hard to use if you have big teeth.

I had to refer back to the online product page to read the English version of the instructions for this teeth whitening kit since I received instructions in a foreign language. It’s pretty simple. You apply the PINK whitening gel directly onto your teeth with the syringe pen. It takes several pumps to get the pink gel flowing. Smooth a thin layer all over the front of your teeth, being careful not to get the gel on your gums. Then place cap on syringe pen and apply clear white strips over your top and bottom teeth just as you would any other white strips. Wait 30 minutes or so for pink color to totally disappear before removing strips. It really does change color and doesn’t leave a pink stain on teeth. Remove strips and rinse mouth. I am on day 2 of the five day strip set. So far I feel like this process works just as well as other white strip sets I have tried, not better, not worse. Will have to see if my teeth are noticeably whiter on day 5. The gel is non irritating to gums, but does kind of leave an unpleasant taste in my mouth. The color changing gel idea is a smart way to make sure strips are left on teeth long enough to clean and brighten them. Not sure if it’s really necessary, but it’s a fun process.

I was very disappointed to find that the only English instruction is a label on the back of the box, while the bulk of the instructions and all the Q&A about use are not in English. The tooth strips are skinny and not very easy to cover my teeth. During the LONG 30-minute treatment time, the strips kept slipping, and the taste was not a very pleasant experience. I tried using the treatments once, but I had so many questions that I couldn't feel comfortable without full instructions, so I couldn't evaluate their effectiveness, whitening, or overall quality.

The old-fashioned vibe of the packaging and of the brand name drew me to this product. I also have to admit to being curious about the pink gel that purportedly acts as a tooth enamel lightening agent. I have now tried the product and wish I liked it better than I do. The instructions that came with the gel (called “booster”) and strips (termed “patches”) are 100% in Korean, a language I don't read. The instructions on the back side of the box are in English, the language I do read, however. It appears to me that the Korean instructions are more comprehensive than the English ones. In the English version there are three drawn illustrations with one-sentence instructions under each. One is first directed to put ‘an appropriate amount’ of the pink booster thinly and evenly on one’s teeth. I am not sure how much is appropriate. The tube of gel is obscure plastic, so I can’t tell how much remains after each application. I had some gel left over after five days though I felt I had plenty on my teeth each day. The second illustration’s text tells one to attach the patches to the teeth. However, with the booster under them, these narrow patches drift all over the surface of the teeth. They do not cover my teeth, top or bottom, but they slip down onto my lower teeth or onto my gums. I had to toss them out before each session was over because they did not stay in place and would become deformed, useless. The third directive is to check your teeth to see them become whiter; recommended time, 1.5 hours, every day. The illustrations show a mouth with pink teeth that have become white. I have not noticed any significant whitening after five days of use, though some coffee stains have diminished. Nothing suggests that oral trays might be needed when using the booster liquid. Since this pink gel is supposed to remain on the teeth for one and a half hours each time it is used, trays would be a good idea. None come with the kit. The booster gel slid down my teeth and into my mouth over time; I spit pink stuff into a sink often during the 1.5 hr. waiting period, and I wore a napkin as a bib so as not to stain my clothing. I did not want to venture into public while waiting for the pink to turn white. I had not considered this when I ordered. Sometimes, when using bleaching strips of a different brand, I have gone out because I don’t think that clear strips are visible. The directions say that “using the patch and booster together gives a 67% more improved effect.” Does this suggest that the results will be 67% better than using the booster alone? If so, the patches should be made to work better with the booster. Perhaps this is the reason I had what I consider to be poor results; the patches did not adhere. I will not order this Euthymol Whitening Program kit again. I would have liked tips on how that booster gel could better work with the patches. The product requires a significant wait-time and I have not seen results. The pink colorant was a disincentive to spending wait-time in public for me.

I really liked this whitening kit, although I was a bit skeptical at first. Seems to work VERY well, and only takes a few days to remove old stains such as from prolonged use of coffee. Simple instructions and well packaged. The initial application doesn't taste half bad, and you can save yourself a LOT of money from going to a dentist for much the same thing. Liking the pearly whites, and will likely go though this a few times a year as a part of general hygiene and maintenance...

Not only is it a five day process but you do this for more than an hour everytime which is not a problem to me because teeth whitening aren’t always an easy job. It did lighten my teeth a little and definitely would try this process again in a couple of months for maintenance or just to lighten it more. The taste is a little bad but tolerable. I also like patting my teeth with a clean towel or tissue to dry it before application.

I am conflicted about this 5 day teeth whitening set. The directions are on the box in English (mine had a label adhered over the back of the box). You receive 5 packs of strips (2 in each pack) and the tube of whitener. The stuff is pink which surprised me somewhat. You are supposed to put the whitener on your teeth and then put the strip over your teeth. I would suggest doing one strip on the upper or lower and then putting the whitener on the other row, followed by the strip. The directions say to leave on for 90 minutes which to me is excessive and hard to do. I felt that the strips did not stay in place and moved around a bit. I do think that my teeth are whiter but I also don’t feel that my whole tooth was covered with the whitener in all places. I think saliva cleared off some of the whitener. I did not notice any sensitivity (and I usually do have sensitivity with some other products). I think this kit is pricey for what it includes.

I am not a regular teeth whitening person but I thought that this product would work if I kept up use of it. I have sensitive teeth and did not experience any extra sensitivity from using this product. Whitening was minimal for me but like I said I would need to continue use for longer to get better results, I think.
