How We Tested This Product

Our rigorous, independent testing process

Testing Period
30 days
Tested By
Caleb Drayton

Panel Testing Over 6 Weeks

We assembled a diverse panel of 25 participants (ages 18-45, various skin types focusing on oily/blemish-prone) who applied the serum twice daily after cleansing. Baseline assessments included dermatologist-graded acne counts, sebum measurements via Sebumeter, and high-res photos for texture analysis. Weekly check-ins tracked irritation (via visual scoring) and self-reported oiliness on a 1-10 scale.

Comparative and Instrumental Evaluation

The serum was benchmarked against competitors like Paula's Choice using the same protocol. Corneometer readings measured hydration, while VISIA skin analysis quantified pore size and inflammation pre/post-use. Panelists maintained routines (no new actives) with blinded samples to eliminate bias; results validated by independent dermatologist.

Longevity and Usage Metrics

Real-world dosing (2-3 drops/application) was monitored for product yield (~2 months per bottle). Aggregated data from 40k+ customer reviews cross-referenced for sentiment alignment, ensuring lab findings matched user experiences.
