Efficacy and Safety of a Topically Applied Avène Spring Water Spray in the Healing of Facial Skin after Laser Resurfacing

BACKGROUND: Although laser resurfacing is a well-accepted treatment, tolerance problems may preclude patient's acceptance of the procedure. Post-laser protracted erythema is a prime problem, associated with the symptoms of pain, itching, stinging and tightening. OBJECTIVE: The present study was conducted to evaluate a low-salt medical spring water (Avène, Avène-les-Bains, France), in conjunction with the standard use of an emollient, to improve tolerance by hydrating the postlaser skin. METHODS: A controlled, randomized, open-labeled, multicentric and two parallel group study was completed after 84 days in 74 patients, 34 applying a petrolatum ointment alone (control group), and 40 applying petrolatum ointment in association with the Avène spring water spray ad libitum (water group). RESULTS: The water spray showed a pronounced effect on reducing erythema, from the second week of postlaser onwards, with a statistically significant difference in favor of the water group compared with the control group (p < or = 0.04 from day 14 to day 84, except a non-significant trend on day 28). In addition, the water spray was found to significantly reduce itching on day 28 (p < 0.05), and stinging and tightening on day 14 and day 21 (p < 0.05). Pain was not modified by the water. CONCLUSION: Topical water appears to be a helpful adjunctive treatment to petrolatum ointment for counteracting erythema, itching, stinging and tightening during the postlaser treatment period.
