I was recently re-reading my favorite skin care textbook (like you do) and I came across this friendly reminder of the importance of exfoliation: the Cell Renewal Factor (CRF). The CRF refers to the process that keeps the cells of the body from building up. We’re constantly shedding and regenerating, although this process slows with age. Babies have a cell turnover rate of about 14 days whereas those who are 50+ require anywhere from 42-84 days to accomplish the same task.

This is why we need to get increasingly savvy about exfoliation as we get older—to keep skin looking as fresh and new as possible. How are you exfoliating? Are you using a scrub? Or something more like this...
