why this region
The argument for reading skin carefully.
Skin is the highest-leverage region for almost every face we read. It's also the region most flattened by filters, which means people consistently underestimate their own. Vaesyn reads it without filter assumptions and routes you to the AM/PM protocol calibrated to your specific signature.
