    Shah NS, Lazarus MC, Bugdodel R

    Published in Journal of the American Academy of Dermatology

    Methodology

    Split-face randomised controlled trial of topical vitamin K before and after pulsed-dye laser treatment.

    Key Findings

    Vitamin K applied after treatment modestly reduced purpura severity; pre-treatment application had no effect.

    Conclusions

    Topical vitamin K may slightly speed bruise clearance but does not prevent bruising.

    Limitations

    Very small split-face design; laser-induced rather than spontaneous bruising.
