Efficacy of a moisturizing cream and facial mask for alleviating skin problems associated with medical mask use: A half‐face, randomized controlled study.

Background: Prolonged use of medical masks has increased skin‐related issues. Aim: To evaluate the efficacy of a facial cream and facial mask in mitigating medical mask related skin symptoms. Methods: Healthy women were randomly assigned to apply a facial cream (n = 32) or a facial mask plus a facial cream (n = 32) on half‐faces after wearing medical masks for 4 h (Tb). Transepidermal water loss (TEWL), dryness score, and redness area were assessed at Tb and 10 min after using the cream (T1) in the facial cream group, and at Tb, 1 h after using the facial mask (T2), and 10 min after using the cream (T3) in the combined use group. Results: In the facial cream group, the treated half‐face showed significantly better improvements from Tb to T1 in TEWL (−2.95 ± 0.38 vs. −0.68 ± 0.35 g/h·cm2, p < 0.001) and skin dryness score (−1.00 ± 0.12 vs. 0.00 ± 0.00, p < 0.001). In the combined use group, the treated half‐face showed significantly better improvements from Tb to T2 and T3 in TEWL (T2, −3.46 ± 0.33 vs. −0.09 ± 0.13 g/h·cm2; T3, −4.67 ± 0.31 vs. −0.28 ± 0.22 g/h·cm2) and skin dryness score (T2, −0.63 ± 0.13 vs. 0.03 ± 0.03; T3, −0.94 ± 0.17 vs. 0.19 ± 0.07) (all p < 0.001) then the untreated half‐face. The combined use group had significantly lower TEWL at T3 than T2 (p < 0.05). The reduction in redness area was similar between the treated and untreated half‐faces in both groups. Conclusions: The test facial cream and mask significantly improved skin barrier function and alleviated dryness symptoms associated with medical mask use, with the combined use offering superior benefits.
