Swiss STS whitening needles have seen advertisements on TV direct sales, but can more than two thousand really turn white safely? But not many people use it. I don't know the actual safety and future side effects. I suggest calling later. Don't be the first experimenter. Many people in the first batch of plastic surgery have many problems, and many things will have adverse consequences after more than ten years or decades. You can't see them in a few years, and you can't ruin your health for a few years.
These things are constantly improving, so it's best not to use them in a hurry.
Alas, I also want to turn white! Apply more mask first.
