Importance of pH in Hyaluronic acid skincare products

Human body is engineered to perfection, with ultimate management of each single cell role in performing certain task.
By far, the biggest organ in our bodies is – the skin, and it performs many tasks. Skin acts as a waterproof, insulating shield, guarding the body against extremes of temperature, damaging sunlight, and harmful chemicals. It also exudes antibacterial substances that prevent infection and manufactures vitamin D for converting calcium into healthy bones.
Our skin is made of layers, and their purpose is to protect our body. Each of this layers has a specific pH that is keeping everything in balance. When your skin barrier isn’t functioning properly (if the pH is too low – acidic, or too high – alkaline), you may be more prone to developing the skin conditions (itchiness, acne, infections).
When using skin care products, it is important to maintain the skin’s natural, slightly acidic pH (around 4.9). This value protects against harmful bacteria and fungi, promotes the growth of beneficial microorganisms and supports the skin’s own enzymes.
A disturbance in the skin’s pH value can be detected by beauticians by measuring pH directly on the skin.
Investigating the pH value of cosmetics that your customers are currently using often provides quick information about the causes of skin problems: Many skincare products are too greasy or even alkaline and shift the skin’s pH value upwards. Now it is important to restore it with suitable, acidic care products and to support the skin in it’s regeneration.
This is exactly  why the skincare experts put maximum effort in ensuring the proper pH of each product while formulated in research & development.
Quality products are not characterized by smell, appearance or price, but by their composition.

One of the top skincare ingredients is hyaluronic acid. Hyaluronic acid is commonly used as a humectant – it’s attracts water.
When applied topically it’s main function is to help the skin maintain moisture.
Hyaluronic Acid has a low pH and can be unstable when mixed with other ingredients. Furthermore, Hyaluronic Acid is an expensive ingredient that might not be worth the price tag if not formulated correctly. However, when actual Hyaluronic Acid is formulated correctly, it can reap major benefits like producing collagen production and hyaluronic acid synthesis.
What we do know, that is pH dependent and special care should be taken while bringing it to formulations.
You need to know the exact pH of your product
The same way these type of products are not diluted before application, they should not be measured in diluted form.
For pH measurements of creams & emulsions Hanna has formulated special pH probes.

HI9810432

HALO2 Wireless Refillable pH Tester 
for Cosmetic Creams
Accurate and easy to use, HALO2 Wireless pH Tester for Cosmetic Creams is ideal for measurements in samples that would be a challenge for standard design pH electrodes. The HI9810432 features a non-porous, glass body that is easy to clean and withstands harsh chemicals.
Refillable electrode
The triple ceramic junction allows a higher flow rate of electrolyte from the reference cell into the solution.This high flow rate provides faster electrode response and a more stable measurement in viscous solutions or samples of low conductivity.The triple junction design prevents both clogging and any potential precipitation of silver at the junction.The fill solution will diffuse through the ceramic junction as it is used.
The HI9810432 can be used as a stand-alone pH tester or can be connected to compatible smart device with the Hanna Lab App via integrated Bluetooth.
  • Compact, waterproof casing, and automatic pH calibration at up to three points, or four points when used with the Hanna Lab App
  • Automatically temperature compensated readings
  • The open-source Bluetooth® protocol allows easy integration with the Hanna Lab App and current Laboratory Information Management System (LIMS).
  • This HALO2 Wireless pH Tester is GLP compliant.
