Help Needed

I do six 12 hours and one 8 hours shift forth nightly. Mostly night shifts. And that's not including the shifts for overtime. So overall in one month I do around 10-14 nights shift. It is quite difficult because I don't get much sleep during the day and during the night when I'm off. I've been doing this job for more than 13 years now. Don't know how many years more I can cope. Looking myself in the mirror make me scared to death because I can see wrinkles slowly showing up. If you know any wrinkle cream that works wonder please do tell me. Help me please. I don't want to get old early.
