- Track trends over days, not single numbers.
What the Numbers Mean
Each brand uses its own scale, so compare readings from the same device only. Use them as a relative guide rather than an absolute measurement.

FAQs
Are skin moisture testers accurate?
They’re good for spotting trends, less so for exact numbers.
What’s a good skin moisture reading?
It depends on the device’s scale. Compare against your own baseline.
Can a tester tell my skin type?
It can hint at dryness or oiliness, but it isn’t a diagnosis.
How often should I take readings?
Daily or a few times a week is enough for tracking.
