Standards
Review methodology
How we select, evaluate, and rate products - and how we keep affiliate relationships out of that process.
Selection criteria
- Availability from reputable retailers.
- Transparent ingredient / concentration disclosure.
- Documented safety information.
- Category coverage across professional, OTC, and DIY options.
Evaluation dimensions
- Effectiveness relative to evidence for the product class.
- Safety profile and sensitivity risk.
- Ease of correct use (fit, instructions, guardrails against misuse).
- Value relative to comparable products.
Independence from affiliate relationships
Product selection and ratings are decided before any commercial arrangement is considered. We participate in the Amazon Associates Program and disclose that relationship beside each linked product.
