Why Kiehl's Retinol Skin-Renewing Daily Micro-Dose Serum comes out ahead

Where Kiehl's Retinol Skin-Renewing Daily Micro-Dose Serum really shines is hydration efficacy, scoring 9.6 compared to Drunk Elephant C-Firma Fresh Day Serum's 6.6.

Both approaches have merit, but the positioning and supporting ingredients make the difference.
