*Cautions*
As this product contains a high concentration of Vitamin C, we recommend avoiding use alongside Copper Peptide products, including our Blue Peptide Serum & Cream, as well as other high-concentration actives such as retinol. For best results, use them at different times of day (morning/evening) to optimize absorption and maximize the benefits of each product.
