Test Mistakes To Avoid

The bare-face test only works if you run it cleanly. A few habits quietly skew the result:

  • Testing too soon: checking before the full hour shows post-cleanse tightness, not your real type
  • Bad lighting: bathroom bulbs hide shine, so judge in natural daylight
  • Recent products: leftover moisturizer or makeup masks how your skin truly behaves

One more trap: testing right after a workout or a hot shower. Sweat and heat spike oil output, so your skin reads far oilier than it actually is.
