Where Kiehl's Retinol Skin-Renewing Daily Micro-Dose Serum really shines is active ingredient strength, scoring 7.8 compared to Round Lab 1025 Dokdo Ampoule's 2.3. Its formula features Niacinamide, Acetyl Dipeptide-1 Cetyl Ester, and Adenosine in high positions, signalling meaningful concentrations.
Hydration Efficacy is another area of separation. Kiehl's Retinol Skin-Renewing Daily Micro-Dose Serum scores 9.6 here versus 7.1 for Round Lab 1025 Dokdo Ampoule. That difference comes down to how each formula is built — the ingredient list tells the story.
Kiehl's Retinol Skin-Renewing Daily Micro-Dose Serum brings Niacinamide, Acetyl Dipeptide-1 Cetyl Ester, and Adenosine as actives, while round Lab 1025 Dokdo Ampoule relies on Chondrus Crispus Extract, Saccharum Officinarum Extract, and Dipotassium Glycyrrhizate. Both approaches have merit, but the positioning and supporting ingredients make the difference.
At premium pricing with a score of 9.0, Kiehl's Retinol Skin-Renewing Daily Micro-Dose Serum delivers strong value. Round Lab 1025 Dokdo Ampoule sits at the budget level with a 7.3 score — the extra cost doesn't translate to better scores here.
