Conditions
Summary
Some individuals have cosmetically un-pleasing prominent blue veins under their eyes or in their temporal regions. Although there are a number of methods to treat these, a simple, effective and safe method is using a type of laser called ND:YAG which targets the blue pigment in the vein. Unfortunately, patients often describe this as uncomfortable or painful. Therefore, the purpose of this study is to determine if using a lidocaine gel prior to treatment will result in a reduction in pain.

Interventions
1cc volume of topical 30% lidocaine in Lipothene gel (Treatment). This was a split body design such that for each patient, one side of the face received the treatment gel and the other side of the face received the placebo gel. Both the treatment and the placebo gel was applied over prominent veins on the infra-orbit and/or lateral temporal area using a cotton tip applicator. Only veins identified by the surgeon and patient undergoing the treatment was treated with the intervention. The intervention and placebo gel remained on the patients face for 15 minutes.
