However, less attention has been paid to air permeability and moisture loss prevention which also play important roles in injury healing. Methods: In the present work, we prepared a hyaluronic acid‐poloxamer (HA‐POL) hydrogel and tested the therapeutic effect of the hydrogel on skin‐wound healing. Results: The HA‐POL hydrogel transformed from sol to gel at 30°C, close to body temperature, and had stable moisturizing properties. HA‐POL hydrogel promoted skin‐wound healing and increased protein accumulation in the wound area. HA‐POL hydrogel allowed greater air permeability than Band‐aid, a typical wound covering. Results from transwell assays showed that the HA‐POL hydrogel effectively isolated skin‐wounds from bacterial invasion. Conclusion: This work demonstrates the advantages of using HA‐POL gel materials in the treatment of cutaneous wounds. 关键词：HA‐POL HYDROGEL hyaluronic acid POLOXAMER 407 skin‐wound HEALING
