Apologies for the confusion, but I'll need the product description to continue. Could you please provide the details of the product?

Main Highlights

BRIGHTENS DULL SKIN - Give your skin a double dose of supercharged brightening and rejuvenation with 15% Vitamin C & EGF Serum; This powerful yet gentle; skin-brightening serum is formulated to reduce the appearance of hyperpigmentation; improve dull skin and help to visibly brighten and even skin tone
POWERFUL INGREDIENTS - Powered by 15% Ascorbyl Glucoside; a stable form of antioxidant vitamin C; to help brighten skin and protect from damage caused by environmental aggressors together with plant-based peptide Epidermal Growth Factor (EGF) to help visibly regenerate skin’s appearance and improve the feeling of elasticity for firmer-looking skin
FOR ALL SKIN TYPES - Suitable for all skin types; especially those with hyperpigmentation, it is cruelty-free and fragrance-free
HOW TO USE - Gentle enough for daily use; Can be used in AM and PM, however, if only used once per day we recommend AM; On cleansed skin apply a pea-sized amount to the face and neck; If you would like to use other skin care products on top, wait around 10 minutes before using them; This gives the skin cells enough time to respond to the EGF and won't affect the rejuvenation process; If using in the PM use on a different night to Retinol and AHA exfoliators
