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.
After about 48 hours, heat in the form of a warm washcloth applied to the bruise for 10 minutes or so, 2 or 3 times a day will increase circulation to the bruised area allowing the skin to reabsorb the blood more quickly. Ultimately, the bruise will fade.
