Testers per product
3 + panel
Every cream is tested by all three members of the BLC editorial team, plus a rotating panel of 4 to 6 reader volunteers recruited per product cycle through the contact form.
Testing Protocol
How we test lifting creams
A reproducible 8-week protocol applied to every product in our catalog before a verdict is published. The specifics below are what we actually do, not the marketing version.
The protocol at a glance
Six fixed parameters every BLC test cycle follows. Deviations are flagged on the review page if they happen.
Skin types represented
4
Each cycle spans all four skin types in our scoring rubric: oily, dry, sensitive, and combination. If we cannot recruit testers for one type, we mark that gap explicitly on the review page.
Age range
28 to 58
Testers span the four age brackets we score products against: 25 to 34, 35 to 44, 45 to 54, and 55+. We do not test mature-skin claims on testers under 40.
Testing duration
8 weeks
Minimum 8 weeks of consistent use before any structural verdict (firmness, wrinkle depth, lift). Hydration, texture, and feel observations are captured starting from day 1.
Application cadence
2x daily
Tested at the brand's instructed cadence, typically twice daily morning and evening. Single-use products (essences, masks) are tested at their labeled frequency.
AM and PM testing
Both
Morning testing happens under SPF and under makeup to surface pilling, flashback, or finish issues. Evening testing happens on bare skin after cleanser and toner.
How we record what happens
Three documentation channels run in parallel across the test cycle. Each feeds the final verdict differently.
Irritation tracking
Captured on a 5-point scale (0 = none, 4 = product discontinued) at week 1, week 4, and week 8. Any redness, tightness, stinging, breakout, or barrier compromise is logged with timestamp and tester ID. Discontinuation events end the test for that tester and are reported in the review.
Before / after documentation
Standardized 3-point softbox lighting, fixed phone-camera distance and angle (front, 3/4 left, 3/4 right). No filters, no retouching, no auto-enhance. Photos captured at baseline (day 0), week 4, and week 8. We do not publish photos without tester consent.
Subjective scoring
Each tester completes a 12-item structured questionnaire at week 4 and week 8 covering texture, finish, fragrance, layering, comfort, and self-perceived firmness. Numerical scores feed our 7-criteria scoring rubric.
What counts as visible lift
We call a cream "visible lift" when at least one of the four perceptible changes below is reported by the tester and independently confirmed by two blinded raters viewing the standardized photos.
- +Improved jawline definition (perceptible reduction in jowl softness)
- +Reduced nasolabial fold depth (perceptible smoothing of the smile-line area)
- +Smoother forehead surface (reduction in horizontal forehead-line depth)
- +Increased mid-face firmness (perceptible reduction in cheek descent)
What we do not measure
The protocol has hard limits. The list below is what we explicitly do not claim, no matter how aggressive a brand's marketing copy gets.
- -Clinical biomarkers (collagen density, elastin content, dermal thickness)
- -Long-term efficacy beyond the 8 to 12 week window
- -Sun damage repair or photoaging reversal
- -Disease-state outcomes (rosacea, eczema, melasma improvement)
- -Comparative efficacy against injectable or prescription procedures
From protocol to score
The data we capture from the 8-week cycle feeds our 7-criteria scoring rubric: tier, ingredient strength, skin-type fit, climate fit, age fit, value, and certifications. The protocol is the input; the rubric is how we translate it into a comparable verdict.
