The main thing is not to overdo it, especially if you’re new to exfoliating. Each time you exfoliate, a regeneration process is set in motion, and this can cause stress for the skin. Be gentle and learn what your skin needs and wants.
As a general rule, exfoliating your face twice a week as part of your weekly skincare routine is enough to keep dry, dull skin at bay, without stripping away too many of your skin’s natural oils. Although oily skin often needs more regular exfoliation.
Exfoliating sensitive areas of the body too often, such as the face, can have the opposite effect and lead to dryness, redness and itchiness.
Age is a factor too. It usually takes around 28 days in younger people for the complete cycle of cells to turnover. However, this process slows down as we age and takes longer, around 45 days to complete. So as we mature, even though we still need to exfoliate we might need to exfoliate less, maybe once a week instead of twice.
