Time dilation doesn’t affect aging at all. In fact it doesn’t affect time from the perspective of the person in question at all ever. Time dilation changes how you perceive someone else’s “time”. So you may live 40 years and see someone come back from a space journey and they only aged 10 years, but to the person on the space journey they only spent 10 years while you spent 40.

To them they lived 10 more years and aged appropriately.
