The Timeline was composed from several sources, one of which is from noted regency romance author Candace Hern. Additional resources such as the Chronology of Culture, What Happened When and The timetables of history have been used to supply over six thousand entries.
Bruising around the mouth and nose area is quite common after injections. I always tell my patients to avoid aspirin, alcohol, NSAIDs, herbals (G's: Ginkgo, Garlic, Ginseng) at least one week before treatment. If a bruise develops, it usually takes about a week to resolve.
The appearance of a bruise changes over time, and you can tell how old a bruise is and where it is in the process of healing by observing its color. Generally, your skin should look normal again in about two to three weeks after an injury.
