The time to make a caffeine eye serum will take longer than you may think. Some of the ingredients will need to blend together and will take up to five days to fully process. This means the serum might take up to a week to prepare based on the time you have available.
Any old makeup bottle or plastic bottle can be used to apply your caffeine eye serum. The best container for your serum will be a glass or plastic eye dropper as you do not need to apply much under your eyes.
