Restoring Severely Sun-Damaged and Dried Out Log Exterior

I recently purchased a log home. The logs are very dry and ”splitting”. This is purely sun damage which has dried them out. I recently started to stain with CWF-UV. The color is very dark in the driest areas. Almost like a purple. Is there a way to restore these before next staining in a couple of years? I have about half the house done now and plan to finish it this week.
