Suffering from allergies can cause a variety of issues, not only difficulty breathing and speaking but your allergies can also cause beauty issues.
For instance nasal congestion may cause blood to flow back up under the eyes and can produce dark circles not to mention puffiness. In order to lessen these affects you may use cold tea bags, cucumbers or even a cold compress (wet towel) on and near the affected area. The caffeine in the tea bags will slightly reduce the swelling but the additional cool temperature help constrict blood vessels, minimize darkness, and it will also help reduce swelling.
