Active Ingredient Strength is another area of separation. The Ordinary Buffet scores 8.4 here versus 4.1 for COSRX The Vitamin C 23 Serum. That difference comes down to how each formula is built — the ingredient list tells the story.
The Ordinary Buffet brings Palmitoyl Tripeptide-1, Palmitoyl Tetrapeptide-7, and Allantoin as actives, while cOSRX The Vitamin C 23 Serum relies on Ascorbic Acid and Allantoin. Both approaches have merit, but the positioning and supporting ingredients make the difference.
