Where Paula's Choice Clinical 1% Retinol Treatment really shines is active ingredient strength, scoring 7.1 compared to Glossier Super Glow Vitamin C Serum's 2.0. Its formula features Retinol, Palmitoyl Tetrapeptide-7, and Dipotassium Glycyrrhizate in high positions, signalling meaningful concentrations.
Hydration Efficacy is another area of separation. Paula's Choice Clinical 1% Retinol Treatment scores 9.8 here versus 5.4 for Glossier Super Glow Vitamin C Serum. That difference comes down to how each formula is built — the ingredient list tells the story.
Paula's Choice Clinical 1% Retinol Treatment brings Retinol, Palmitoyl Tetrapeptide-7, and Dipotassium Glycyrrhizate as actives, while glossier Super Glow Vitamin C Serum relies on Melia Azadirachta Flower Extract, Melia Azadirachta Leaf Extract, and Coccinia Indica Fruit Extract. Both approaches have merit, but the positioning and supporting ingredients make the difference.
Both sit in the mid-range bracket, so value comes down to formulation quality. Paula's Choice Clinical 1% Retinol Treatment gets the nod here with its 8.9 overall score — you're getting more for a similar outlay.
