Again, it probably has to do with age, but instead of "quitter's acne", I just got very oily skin without any breakout around my third week. It subsided in about 10-days and left me with a much more healthy complexion. Now if it would just extend to these old dry hands!! LOL But I have noticed less itchy legs and feet (another aging factor), so I would have to say it has been an all-over improvement. Remarkable what those ole ciggy chemicals actually affected!
