BrightBoost 無過氧化物美白粉

My dentist warned me about peroxide sensitivity, so the PAP formula was the main reason I tried this. Two weeks in, my coffee stains are visibly lighter and there's zero of that harsh tingling I used to get.

The silica really does the heavy lifting—my coffee stains are noticeably lighter after just a week, and there's zero of that harsh peroxide taste I hated in other powders. It's a bit messy to scoop, but the results make up for it.

I was skeptical about a peroxide-free whitener, but the PAP formula really did lift coffee stains after about a week of nightly use. The powder has a fine grit that dissolves quickly, no harsh chemical taste either.
