Brief summary

Patients will be randomized either to receive standard daily dressing or hydrocolloid dressing using a randomization generator. After closing the wound with the sutures,the scar will be covered by a hydrocolloid dressing, which will be left in place for 7 days(Experimental) or the standard dressing (Control) that will be covered with petrolatum jelly and bandaging during this time period, which has to be re-applied daily. Patients and dermatologic surgeons will then complete surveys 7 days, 30 days, and 90 days after surgery to evaluate the cosmetic appearance of these scars.

Interventions

A single hydrocolloid dressing will be applied to the surgical site for 7 days following dermatologic surgery

OTHERPetrolatum jelly dressing

The patient with the control wound will be covered with petrolatum jelly during this time period, which has to be re-applied daily.

Outcome results

Primary

Cosmetic Outcome

Patient and surgeon assessment of cosmetic outcome using modified visual analogue scar scale. The minimum value is 1 and the maximum value is 10. 1 is the worst possible scar appearance and 10, is the best possible scar appearance.

Time frame: 30 days

Population: The above numbers reflect the number of patients who responded at 30-day postoperative followup and is smaller than the original number of participants in each arm and the number of participants analyzed at 7-day followup due to lack of response by some participants
