How We Tested
Each serum was used by our test panel for six consecutive weeks. We tracked improvements in fine lines, texture, tone, and overall radiance, alongside tolerability markers like dryness, peeling, and sensitivity.
Our consulting dermatologists, Dr. Maya Patel and Dr. James Lin, independently evaluated ingredient lists, formulation quality, and published clinical data for every product before testing began.
