What is the significance of pH in skin care products?

• A. It affects skin barrier function and product efficacy
• B. It determines fragrance strength
• C. It changes the texture of the product
• D. It enhances color absorption

Answer: (A)

The significance of pH in skin care products primarily lies in its impact on skin barrier function and the efficacy of the products. The skin has a natural pH level that typically ranges from 4.5 to 5.5, which is slightly acidic. This acidity helps to maintain the skin's protective barrier, known as the acid mantle, which plays a crucial role in preventing moisture loss and protecting against harmful pathogens and environmental pollutants. When skin care products are formulated with a pH level that is too high or too low, it can disrupt this delicate balance. A product that is too alkaline may compromise the skin's barrier function, leading to dryness, irritation, and increased susceptibility to infections. Conversely, ingredients with an appropriate pH can enhance product absorption, ensuring that active ingredients are effective and well-tolerated by the skin. Thus, maintaining the correct pH in skin care products is vital for both protecting the skin’s health and ensuring that the products perform effectively.
