Abstract:
Background: Fractional erbium 1550 nm laser is an effective treatment for improving many skin problems. However, the side effects and complications have been reported. Nowadays there are no standard treatment for post laser wound care. Betaglucan is considered using as a natural skin care. It can promote wound healing, and also have soothing and moisturizing skin. There has been no clinical trial of betaglucan for post procedural wound care after laser treatment.
Objective: To evaluate the effect of 10% betaglucan mask sheet for post procedural wound care after fractional erbium 1550 nm laser by comparing with the placebo.
Method: A prospective, randomized, double-blinded, placebo-controlled study were performed and enrolled 30 mild to moderate photo aging skin subjects who underwent fractional erbium 1550 nm laser in to the study. All subjects were randomly assigned to receive either betaglucan mask sheet or placebo. The measurement of trans epidermal water loss by Tewameter® TM 300, erythema and melanin index by Mexameter®MX18 were evaluated at baseline, after laser immediately, and also in day 3, day 7,day 10 and day 14 after laser treatment. Adverse effects were also evaluated. Betaglucan mask sheet group demonstrated significantly greater reduction in trans epidermal water loss at day 7 post-laser than the placebo group (p value = 0.02). Erythema and melanin index by Mexameter MX18 measurement and adverse effects did not show the differences between two groups at any time points. There was no serious side effect. Betaglucan mask sheet is effective and better reduction in trans-epidermal water loss than the placebo for post-procedural wound care after fractional erbium 1550 nm laser treatment.
Results: Betaglucan mask sheet group demonstrated significantly greater reduction in transepidermal water loss at day 7 post-laser than the placebo group (p value = 0.02). Erythema and melanin index by Mexameter MX18 measurement and adverse effects did not show the differences between two groups at any time points. Betaglucan group also reported with high satisfaction rate (80%). There was no serious side effect.
Conclusion: Betaglucan mask sheet is effective and better reduction in transepidermal water loss than the placebo for post-procedural wound care after laser treatment and has no skin irritation effect.
