Alpha-Citrus™ (Alpha Glucosyl Hesperidin) Usage Rate for Eye Area

Based on the product information for Alpha-Citrus™ (Alpha Glucosyl Hesperidin), the recommended usage rate is 0.5-3%.

For skin under 35 years old, a rate of 1-2% is recommended. However, for skin older than 35 years, a rate of 3% is recommended.
