Review on 🌈 Universal Litmus Test Strips: Expanded Application by Matt Hamilton

Very inconvenient to use - as a beautician I like to test the pH of my products to make sure I am keeping my skin barrier healthy. The only thing this thing read accurately was the water, which turned it green. I tested it with products that already had a pH so I could compare the results to make sure they were correct. As for my scrubs, the readings for all of them were about the same, even though their bottles said different pH levels. Extremely frustrating and frustrating because basically all I can do is accurately test the water. Now I'm looking at a hyaluron pen that just needs to be dipped in water and then it works like clockwork.
