I don't think any "healing process" is necessary unless the capacitor 
experiences voltage breakdown. This is unlikely in a low voltage circuit.

Longer integration times are available by changing the resistors 
instead of the capacitors. Modern opamps are available that can run 
rings around the old ones (probably LM208, as I recall) originally 
used. You just have to get the input bias currents much lower, 
allowing higher circuit resistances.
