Question: 1 / 400

What is the purpose of pH in cosmetology products?

To enhance color vibrancy

To maintain skin integrity and prevent irritation

In cosmetology, pH plays a crucial role in maintaining the skin's integrity and preventing irritation. The skin has a natural acidic barrier known as the acid mantle, which helps protect it from external aggressors and pathogens. Using products with a pH that is too high or too low can disrupt this barrier, leading to issues like irritation, dryness, and an increase in sensitivity.

When formulators create cosmetology products, they aim to match the pH of the product closely to that of the skin, which typically ranges from 4.5 to 5.5. This helps ensure that the product is gentle and effective, allowing it to cleanse, moisturize, or treat the skin without causing harm or discomfort. Therefore, the appropriate pH level in cosmetology products is fundamental for enhancing skin health and ensuring consumer safety and comfort.
