Bio Shop™ pH Test Strips are high-quality, easy-to-use strips designed to quickly measure the pH level of liquids, making them ideal for DIY skincare, cosmetic formulations, soap making, shampoos, creams, lotions, and serums. These strips help you ensure your formulation is skin-safe by confirming the correct pH balance, which is especially important when working with active ingredients like acids, niacinamide, or preservatives. Simply dip the strip into your solution for a few seconds and compare the color change with the provided chart for accurate results. Always test at room temperature and avoid touching the test area with wet fingers for best accuracy, and store the strips in a dry, sealed container to maintain reliability.
