Comparison of a novel wound dressing vs current clinical practice after laser resurfacing

There are many postprocedure skin care options, but no consensus on the best formulation to optimize healing. Silicone gels have only been used to treat keloids and hypertrophic scars and typically applied after the wound has healed. This study compared the healing response after fractional ablative erbium laser resurfacing with a petrolatum-based ointment and a silicone gel.

A randomized, open-label, split-face study was performed. Ten subjects underwent Erbium:YAG (Sciton) fractional laser resurfacing. Patients were randomized to apply a petrolatum-based gel or a silicone gel (Stratacel^® ; Stratpharma) on either the right or left side of the face. Subjects applied the products twice a day for 7 days and were evaluated in person 7, 30, and 60 days postprocedure. Subjects reported on the overall general aesthetic outcome, perceived pain, itch, and tightness via questionnaires using the Global Aesthetic Improvement Scale and the Wrinkle Severity Rating Scale (WSRS).

All subjects healed without complications. By day 60, there was no difference in signs and symptoms of healing between the two different dressing approaches. However, patients treated with the silicone gel had less post-treatment erythema and hyperpigmentation.

A novel silicone gel resulted in reduced signs of erythema and hyperpigmentation postprocedure, without an increase in adverse events. Additionally, the silicone gel dries to form a thin, full contact film and can be covered with sunscreen or cosmetics once dry. This new silicone gel presents a good option for postprocedure care after ablative fractional laser resurfacing.
