Absolutely! Another problem with skin typing is the assumption that your skin (and skin type) will be the same forever, or at least until you age. That, too, is rarely the case. If your skin-care routine focuses on skin type alone, it can become obsolete the moment the season changes, your work life becomes stressful, or your body experiences hormonal or diet fluctuations or other physical changes, and whatever else life may bring.
To complicate things even more, in any given period you may have multiple skin types! It is not unusual for women to have a little bit of each skin type simultaneously or at different times of the month or week. An overview of how your skin behaves and changes is necessary to assess what your skin needs so you can then respond by applying the appropriate products to those problems areas.
