Crest Whitestrips with LED Light vs Regular Strips
Crest sells a premium kit that includes a handheld Blue LED Light. Is the extra $25 cost worth it?

- Blue LED Light Function: The handheld blue light device targets hydrogen peroxide molecules to accelerate chemical breakdown during the final 10 minutes of application.
- Speed Result: Reaches maximum shade brightness slightly faster (in 10 to 14 days vs 20 days).
- Verdict: The regular Professional Effects kit produces identical final shade results by day 20. Unless you need ultra-fast results for an event next week, save your money and buy the standard kit.
