Worsening that means some of the rashes that may develop related to wearing a mask would be well suited to be treated with a topical Niu Age Skin Serum steroid so I'm not saying that tubful steroids and necessarily a hard-and-fast no but I caution you against self treating with them because problems can arise especially if you're treating the wrong type of rash with a topical steroid so3 I would say try and resist the urge to self treat with a topical.
