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 Garnier Brightening serum's 7.2. With Glycerin, Butylene Glycol, and Pentylene Glycol in its top ingredients, Kiehl's Retinol Skin-Renewing Daily Micro-Dose Serum delivers stronger moisture-binding capability.

Irritation Risk is another area of separation. Kiehl's Retinol Skin-Renewing Daily Micro-Dose Serum scores 9.5 here versus 7.6 for Garnier Brightening serum. That difference comes down to how each formula is built — the ingredient list tells the story.

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