Evidence Becomes The Purchase Criterion After Disappointment
Clinically validated multi-wavelength masks grow at 11.7% against 7.8% for the category because a second-time buyer behaves completely differently from a first-time one. Someone who spent several hundred on a device that produced nothing looks for trial data on that exact product rather than for a wavelength claim, and around 22% of devices can supply it. That group is growing steadily as the installed base of disappointed owners accumulates, which makes evidence a commercial asset rather than a regulatory formality. The installed base of disappointed owners from 2021 is where most of that demand is coming from.
