medicube PDRN PINK PEPTIDE SERUM

A serum should deliver at least one evidence-backed active ingredient, and this Medicube PDRN Pink Peptide Serum doesn't clear that bar—neither PDRN nor the peptides it references have sufficient clinical evidence to qualify. Skip it and put your money toward a serum with a proven ingredient like niacinamide, retinol, or a well-studied acid.
