Your skin hydration can change a lot during a short period of time. The weather, products on your routine, change of atmospheres and even your alimentary habits and sleep will affect your skin moisture.
There are many devices on the market that can measure your skin hydration in a matter of seconds so you will know if a more powerful moisturizer is needed or if your new products are working. Also, dermatologists can use these devices to provide diagnostics and follow a treatment result.
Most devices with this objective will measure the stratum corneum water content, the quantity of water that is present on the external layer of the skin. For this, they will use the electrical properties of the skin (capacitance, conductance, or impedance) to obtain the results in real time. These methods are noninvasive and very easy to use, available from different manufacturers and provide reliable results.
Among the wide number of options, we can cite the Corneometer®, which is one from the German company Courage & Khazaka and is based on capacitance principle. It is mostly used in cosmetic research and by dermatologists and is known for being very harsh in dry conditions. The results are given in arbitrary values. The higher the value is, the higher the skin hydration will be.
The SkinUp® is more portable and measures the skin moisture, oiliness, and elasticity through the impedance principle. The measurements are given in arbitrary hydration percentage units and although it is not very cited in the scientific literature, it has a lower price range and works very well for its objective.
If you want to invest in a skin hydration device, look for the ones that are based on electrical properties of the skin and enjoy! Your skin will be more hydrated and will look healthier than ever.
