Are Photosensitive Gels The Only Whitening Gels That Work With LEDs?

🎙️ Whitening Wednesday Episode 87: Are Photosensitive Gels The Only Whitening Gels That Work With LEDs?

📣There’s a big myth in whitening that only “photosensitive” gels actually work with an LED light — and if your gel doesn’t have a photo initiator, your light is just for show. Let’s science behind peroxide activation, and why the “photosensitive gel” label is more marketing than truth.

⏱️ Timestamps:
00:00 – Intro: Truth or Trend: Are photosensitive gels the only gels that work with an LED?
00:55 – The myth explained: LED is useless without a “photosensitive” gel
01:20 – The science: Peroxide gels (hydrogen + carbamide) and how they oxidize stains
01:55 – Chromophore theory: Free radicals + reactive oxygen species doing the real work
02:44 – Blue spectrum LED: Why light/heat accelerates peroxide breakdown
03:01 – Photo initiators explained: Titanium dioxide as the common additive
03:40 – Marketing gimmick: Why companies push the “photosensitive only” message
04:20 – The truth: Peroxide reacts to LED with or without a photo initiator
05:00 – Recap + final verdict: ❌ You don’t need a “special photosensitive gel” for LEDs to work ✅ All peroxide-based gels accelerate under light/heat energy
05:45 – Final mic-drop: Your LED is there to help accelerate oxidation, not to complete it — don’t fall for the photosensitive gimmick.
