To enhance expression of an antioxidant-related substance in an epidermis by using a diacylglycerol PEG adduct, a method for enhancing expression of an antioxidant-related substance in an epidermis is provided which includes applying a diacylglycerol PEG adduct to the epidermis as an active ingredient. The antioxidant-related substance is an oxidative stress response gene, an antioxidant enzyme, or an antioxidant protein. The diacylglycerol PEG adduct is selected from the group consisting of PEG-12 glycerol dimyristate (GDM12), PEG-12 glycerol distearate (GDS12), PEG-23 glycerol distearate (GDS23), PEG-23 glycerol dipalmitate (GDP23), and PEG-12 glycerol dioleate (GDO12).

Disclosed herein are fully synthetic polymer-based lung surfactant materials, for the first time, as next generation SRT. In vitro studies on these polymer lung surfactants show that the candidate materials effectively mimic the surface tension controlling properties of currently marketed natural lung surfactants. Further, the polymer lung surfactants have strong protein resistance, which makes this class of materials promising also for potential use in Acute Respiratory Distress Syndrome (ARDS) treatment.
