치아미백에 효과가 있나요?
My oral care item is none other than Perio's White Now!
White Now is a stick-on teeth whitening product.
I've been drinking too much coffee for a while, so one day I noticed my teeth in a smiling photo looked yellower than before... haha.
So, I bought this product in a hurry, but it offers good value for money, and I trusted it the most because the manufacturer was LG Household & Health Care.
They said to use it for 7 consecutive days, but I couldn't because I was busy. I used it intermittently every two or three days, and I definitely saw a whitening effect!
It seems like it has returned to normal a bit now that I'm drinking a lot of coffee again and not using the product... but if you use it once in a while when your teeth look severely discolored, I think you can see results like mine.
I think I'll be buying and using this every two or three months, too, haha. I recommend it to anyone who is concerned about their tooth color like me.
