Who pays us (and what that does not buy).

When you click a partner link on this site and later buy, book, or sign up, we may earn an affiliate commission. Partners may include clinics, brands, telehealth services, or other companies we write about. You do not pay more because you came through our link.

Affiliate links are a form of advertising. If we run display ads or labeled sponsored posts later, those are advertising too. We will mark sponsored content so you can tell it apart from our own guides.

• Clinics and brands can't pay to rank here.
• A commission never changes our rankings or our verdicts.
• Money cannot buy a "Worth it?" chip, and it cannot bury a risk, a recovery downside, or a "who should skip this" note.

If a page on this site ranks products, services, or clinics, it will include a short line near the top, next to an advertising disclosure, that points back to this page. Pages that don't rank anything won't carry that line.

We choose what to cover. We choose the sources, the dates, and when to update or correct a page. Partners don't write our copy, and they don't get to sign off on a ranking. For the full method, see our Editorial policy. For a longer money explainer, see How we make money.
