sharpen old photograph

[Shinnen]

Hi,
I have a picture of an old photograph (about 55 years old, black and white) that shows the pixels when it's blown up. I'm hoping there's a way of making this a little clearer. I don't have the original print, just a picture of it.
Thanks,

Try the menu Filter > Noise > Dust reduction with a radius 5 or 7

Hi Antonio,
That helps a bit, but it's still fairly fuzzy. Is there a way of somehow producing a graduation in shading between pixels? I'm not really sure how to say what I mean.
Thanks,

Hi Antonio,
Thanks again. I think I figured it out. I found that increasing the size and resolution, then smoothing (blur/ smudge/noise reduction) the face helped quite a lot.
