Study Summary
The objective of this study is to assess the comparative utility of topical formulations in hastening the resolution of skin bruising. For each subject, four standard bruises of 7 mm diameter each were created on the bilateral upper inner arms, 5 cm apart, two per arm, using a 595-nm pulsed-dye laser. Randomization was used to assign one topical agent (5% vitamin K, 1% vitamin K and 0.3% retinol, 20% arnica or white petrolatum) to exactly one bruise per subject, which was then treated under occlusion twice a day for 2 weeks. A dermatologist rated bruises in standardized photographs immediately after bruise creation and at week 2.
Primary Outcome
Mean change in bruising level detected by dermatologist rater on Visual Analogue Scale at 2 weeks compared with baseline for each of the four agents (Petrolatum USP, Vitamin K and retinol ointment, Vitamin K ointment, Arnica ointment). When responding to a VAS item, respondents specify the bruise severity by indicating a position along a continuous line between two end-points (0 and 10, 10 being the most bruised).
Interventions
- DRUG Petrolatum United States Pharmacopeia (USP)
- DRUG Vitamin K and retinol ointment
- DRUG Arnica ointment
- DRUG Vitamin K ointment
