Usage instructions

After cleansing and applying toner in your skincare routine, remove the cap and replace it with the dropper. Dispense 2 to 3 drops at the serum stage, apply evenly across the entire face, and gently pat with your palms to help absorption. Secure the dropper and shake it gently from side to side before use. Evening use is recommended; if used during the day, apply sunscreen alongside the product to help protect the skin and active ingredients. For best freshness maintenance, store the product in the refrigerator after opening, and complete usage within 3 months of opening.
