摘要： A wearable article, a moisturizing composition and a method for preparing a wearable article have been disclosed. The wearable article includes at least a layer of a flexible material, wherein the flexible material is an elastomeric material and an inner surface of the layer of flexible material is a coated with a coating formulation comprising 1% to 7% by weight of a moisturizing composition and 93% to 99% by weight of solvent. The moisturizing composition includes 10 to 30% by weight of at least one humectant and 1.0 to 5.4% by weight of at least one antioxidant. Thereby, the present invention reduces transepidermal water loss (TEWL) and promotes skin barrier recovery.
