BACKGROUND Coronavirus disease 2019 has rapidly spread all over the world. Personal protective equipment (PPE) including masks and gloves is needed to avoid transmission. Adverse skin reactions associated with PPE have been described, but there is no information regarding objective measures to assess skin impairment related to PPE. OBJECTIVE The aim of the study was to evaluate the impact of using facial mask and nitrile gloves on epidermal barrier function and skin homeostasis. METHODS A cross-sectional study was designed. Thirty-four health care workers wearing nitrile gloves and a mask for 2 hours were included. Transepidermal water loss, stratum corneum hydration, erythema, and temperature were measured. RESULTS Transepidermal water loss (31.11 vs 14.24 g·m-2·h-1), temperature (33.29°C vs 32.57°C), and erythema were significantly greater at the area covered by gloves compared with the noncovered area. Transepidermal water loss (22.82 vs 13.69 g·m-2·h-1), temperature, and erythema (411.43 vs 335.52 arbitrary units) were significantly increased at the area covered by mask, whereas stratum corneum hydration was lower. Transepidermal water loss was greater at the area covered by a surgical mask than at a filtering respirator mask coded filtering facepiece 2 (27.09 vs 18.02 g·m-2·h-1, P = 0.034). CONCLUSIONS Skin homeostasis and epidermal barrier function may be impaired by gloves and mask use. High-quality PPE should be provided, and adequate skin prevention measures should be implemented to reduce epidermal barrier damage.
