What An Extra Has To Prove Before We Recommend It
An optional extra arrives with a price and a promise, and the promise is usually the louder of the two. Before an extra earns a good rating on this site, it has to get past three plain checks.
What an extra has to prove
First, it has to be named. A bundle that says "add-on included" without listing the treatments inside it cannot be priced. Second, it has to show the price it replaces, so the saving can be tested against a real number. Third, it has to give a benefit window, meaning how long the effect is expected to last, with a source behind it. An extra that passes none of these sits low, however large the headline saving.
Some optional extras pay back and some are mostly marketing. These checks are how the two get separated.
Reading offer terms and independent studies
Estimates here start from the offer's own terms and from independent studies, read before any value is put on an extra. The provider's terms say what is actually being sold. Independent material says what to expect from it. For general background, Harvard Health's guidance on skin care for aging skin, Cleveland Clinic's overview of laser procedures and the laser hair removal overview from the AAD are useful to have open.
How the rating method handles headline savings
The ratings cover Ann Arbor, Michigan. Providers are ranked by the count of non-surgical treatments each lists on its own published services page, and the count is read from that page, not from advertising. A longer menu shows range. It does not show that any single extra repays its cost, so the ranking never stands in for a verdict on an offer.
A headline saving is the gap between two numbers. The method asks for both of them, and where one is missing the saving is treated as unproven.
