To get the pH value, moisten the skin surface, make a mark with the pencil, wait for 15 seconds, and then compare the color to the chart. This product is very helpful for determining clients' skin pH.

Using these pH measuring pencils is easy. First, wet the skin surface with water. Then, use the pencil to make a mark on the wet area. Wait for about 15 seconds. After that, compare the color of the mark to the included color chart to get an approximate pH value. When using the pencils, make sure the skin is clean and the water used for wetting is pure. Don't press too hard when marking to avoid inaccurate results. After use, keep the pencils in a dry and cool place. If the color of the pencil tip fades or changes, it might be time to replace the pencil.
