Reporting Groups
  Description
Average Bruise Improvement pulsed dye laser induced four 1 cm bruises at least 5 cm apart on the skin of the upper arm (two bruises on each arm). Subjects applied different topical ointments on each of their bruises twice a day. Ointments were: 5% vitamin K cream; 1% vitamin K and 0.3% retinol cream; 20% topical arnica; white petrolatum United States Pharmacopeia (USP) as placebo.

  Limitations and Caveats
  Hide Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
As only laser-induced bruising on the inner arm was studied, it remains to be seen if this result can be generalized to other postoperative bruises and at other anatomical sites.
