Our Methodology
How We Test & Review
Every score on LumaGrid Reviews follows the same process. No shortcuts, no sponsored placements — just honest research and transparent scoring you can actually trust.
Our 5-Step Process
Category Research
We start every guide by mapping the full competitive landscape. We identify all major products in a category, study manufacturer claims and clinical data, and read real-world feedback across Amazon, Reddit, skincare forums, and beauty communities. This ensures we're comparing the right products against each other — not just the ones with the biggest marketing budgets.
Expert Source Aggregation
We compile and synthesize reviews from trusted expert sources — board-certified dermatologists, aestheticians, hair stylists, beauty editors at Allure and Byrdie, and wellness specialists. We look for consensus across sources rather than relying on any single opinion. When experts disagree, we flag it and explain why.
Real User Validation
Lab conditions and expert opinions don't always catch long-term issues — build quality failures, skin reactions that appear after weeks of use, or software problems that reviewers missed. We cross-reference thousands of verified reviews from Amazon, Sephora, and Ulta to surface common complaints and repeated praise across a large sample of real owners with different skin types and hair textures.
Value Assessment
A product's score is never purely about raw results — it has to be appropriate for its price point. We score products relative to what you pay. A $79 LED mask that delivers noticeable results can outscore a $400 device that only marginally outperforms it. We always flag when a budget-friendly alternative performs nearly as well as the luxury pick.
Editorial Scoring
Our final ranking is a weighted composite across the five criteria below. We update scores when a product receives a meaningful firmware or formula update, when new competitors enter the market, or when long-term reliability data from real users changes our assessment. Guides are reviewed at minimum every six months.
Scoring Criteria
How we weight each factor in our final editorial score
Editorial independence: LumaGrid Reviews does not accept payment for positive reviews, sponsored rankings, or "featured" placements in our buying guides. Brands have no editorial input. Our affiliate commissions are earned after the fact and have no bearing on our recommendations. If we think a product is overpriced or underwhelms, we say so.
