*For best results, use immediately after purchase. Once opened, store upright in the refrigerator.
*Cautions*
1. For first use, attach the dropper included in the product package.
2. To preserve the active ingredients, we recommend using within 2 months of opening.
3. Can I use a highly concentrated serum only in the evening? No! This serum can be used both in the morning and evening.
4. If used in the morning, always follow with a sunscreen of SPF 30 or higher.
5. As this product contains a high concentration of Vitamin C, we recommend avoiding use alongside Copper Peptide products, including our Blue Peptide Serum & Cream. For best results, use them at different times of day (morning/evening) to optimize absorption and maximize the benefits of each product.
