[Routine Help] Event prep advice?

I have a major event coming up next week and was hoping for some suggestions on how to look my best. I know this has come up before, but the most recent post on it I could find was from several years ago, and I am wondering if there's new stuff that people can suggest. I remember years ago, Jane Pratt describing a routine on xojane, that included zinc? Or something like that...colloidal silver? I can't remember, but she had a 48-hour or so prep that she said made her glow. I want to glow. I'm 51, in peri, and have a pretty solid regular routine, including spf, but am wondering what I could do that is beyond my normal stuff. I don't think i have time for any in-salon stuff, but I am ok to spend a bit, if there is something I can do at home.
