How To Use

After cleansing, during the serum phase, shake the bottle lightly once or twice from side to side and apply a few drops to the skin. Use fingertips to gently massage and absorb the serum, starting from the inside of the face working towards the edges. For the first use, attach the enclosed dropper in the product package. Recommended to use within 2 months of opening due to active ingredient protection. Highly concentrated serum should only be used in the evening? NO! This serum can be used in the morning and/or afternoon. If applied in the morning, be sure to use with a SPF of 30 or higher.

Precautions: Gas can be generated due to the nature of vitamin C. When opening the cap, it may make a sound. With a specially designed cap to seal vitamin C, it can be safely stored by controlling the gas generated inside the container. If you shake it before opening, it may overflow, so shake lightly, from left to right after fastening the pipette. Extra room in the container has been secured for safe use. Vitamin C products are recommended to be used within 2 months of opening due to easy discoloration caused by oxidation. Keep it away from high temperatures and direct sunlight. It is recommended to be stored in the refrigerator when it is not being used every day after fastening the pipette. Keeping it refrigerated can help maintain the freshness of the vitamin C. KEEP REFRIGERATED (3~10°C) *Please use immediately after purchase and store upright in refrigerator once opened.
