How does Ken Walker's collaboration with Colgate Optic White outperform other whitening products?

Ken’s collab with Colgate Optic White High Impact Toothpaste stands out because it fits real, everyday use instead of feeling like a gimmick. In that post, Ken mentions being “usually skeptical about other whitening products” but still chose to start a journey with Optic White, which says a lot about trust and results over hype.

Compared to strips or one-off treatments, this kind of toothpaste:

1. Works as part of your normal brushing routine
2. Is easier to stay consistent with
3. Aims for whiter teeth over time instead of a harsh quick fix

What matters most to you in a whitening product: speed, sensitivity, or long-term maintenance?
