The arithmetic we keep doing
We aren't interested in whether a treatment is good. Most of them work about as well as the honest descriptions say they do. We're interested in the sums underneath.
A neuromodulator that peaks at two weeks and fades at month three isn't a purchase, it's a subscription with an awkward billing cycle. A peel booked for the last week of June is a different product than the identical peel booked in January, because the sun is doing half the work in one case and undoing half of it in the other. A syringe priced at a flat rate is a volume, not an outcome, and two people can buy the same volume and get results that aren't remotely comparable.
None of that is secret knowledge. It's just rarely assembled in one place, in an order that matches how a real decision gets made.
