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.
