Cao Y, Wang P, Zhang G, et al. - In the present study, the researchers sought to assess the effectiveness and tolerance of skin care regimens containing β-glucan (Dermdoc®;Songyang Biotech) in repairing postlaser inflammation and skin barrier dysfunction after fractional laser therapy. In total, 20 patients with facial atrophic acne scars who accepted fractional laser therapy were selected: 10 patients treated with ablative fractional CO2 laser and 10 patients treated with 1565nm nonablative fractional laser. The skin care regimens were well tolerated and had no obvious side effects. Skin care regimens containing β-glucan may aid in the recovery of skin inflammation and barrier function following fractional laser therapy.
