While appearance might be the first thing others judge you by - it is really the person you are inside that matters.
I didn't look at your pic. But I am 55 and hope that what I ran up against over years and the actions I took might be helpful to you.
Take a few extra minutes to style your hair.
Apply a little make-up to accentuate your best features.
Dress professionally - in a way that reflects the job you want to get.
If you feel unsure about the best styles of hair, make-up and clothing - head off to the stores. There are so many free consulting services these days! And, if you do have to spend a little bit of $ for good advice - the return on the investment might just shock you.
Wishing you the best.
