For optimal performance and ingredient stability, we recommend avoiding concurrent use with highly concentrated peptide-based products, including our Blue Peptide Serum and Blue Peptide Cream, as well as other high-strength actives such as Retinol products and our Niacinamide 15 Serum. We recommend applying these products at different times of day rather than within the same routine. For example, use Vitamin C 23 Serum in the morning and Blue Peptide Serum or Blue Peptide Cream in the evening.\u003c\/li\u003e\n \u003cli\u003eANTIOXIDANT SYNERGY: A powerful antioxidant complex works in synergy with Vitamin C to help neutralise free radicals.
