Affiliate & advertising disclosure
Editorial independence & funding
- Funding
- Affiliate and referral links. If you start a treatment or buy a product through one, we may earn a commission — at no additional cost to you.
- Grading
- Grades reflect published evidence and a fixed, public rubric. A commission can never raise a provider's grade or move it up a ranking.
- Independence
- We accept no payment to review, re-grade, or feature a provider, and competitors we compare against are shown without any affiliate tie.
Full method and ledger: our transparency report.
Longevity Graded maintains editorial independence. Product rankings are determined by published evidence and editorial assessment. Affiliate or referral relationships never alter our rankings or conclusions.
