To use this cream, first clean and moisturize your face. Then, take a small amount of the cream on your finger or a makeup brush and gently apply it to the areas with freckles, acne, or other blemishes under your eyes. Blend it well with your skin for a natural look. Remember to keep the cream in a cool and dry place. If you have sensitive skin, it's a good idea to do a patch test first. Also, make sure to close the cap tightly after each use to maintain its quality.
