Right after cleansing, sebum has been washed away, and it builds back up over time. That's why even with a measuring device, the rule is to wait a set period after cleansing (usually 30 minutes or more) before measuring. When people take a selfie differs from person to person and from day to day. On top of that, the shine you see in a photo depends not only on sebum but on light reflection, sweat, and whatever products you've applied. INSKINVIEW assessing Radiance (how evenly light reflects) within Skin Texture is a different matter from measuring the amount of sebum.",[13,28,29],{},"Moisture is even harder. Skin hydration is measured with devices that use the skin's electrical properties — it isn't visual information. Skin that looks dewy and skin that actually holds a lot of moisture are not the same thing.",[13,31,32],{},"In my first post, I wrote that even device readings shift with temperature, humidity, and where the probe is placed.

Even if you don't mind them yet, they accumulate into visible change over time, and keeping a record of that trend has value in itself.
