There either is some extra step you can pay for to halt your own aging or some technology from another Singularity for that.
In Lobotomy Corporation, Chokmah was visibly older than when he was Benjamin in spite of being only a few days into the loop. Manipulating the protocols made him either age faster or keep piling up natural age through the loops, I don't remember which. It isn't like Ayin cared enough for a QoL function to keep him young since he gets Benjamin killed some days in and turns him into a Sephira. I'd guess something like K Corp. ampules could restore age if necessary and someone rich enough to live weeks in days could likely afford some of those.
