What role does pH play in skincare products?

The role of pH in skincare products is crucial, especially when it comes to how these products interact with the skin. pH levels can significantly influence the effectiveness of a product, particularly its cleansing properties. Skin has a natural pH level, usually ranging from 4.5 to 5.5, which is slightly acidic. Products that are formulated to be either too alkaline or too acidic can disrupt this balance, leading to potential irritation or compromised skin barrier function.

When a cleanser has an appropriate pH, it can effectively remove dirt, oil, and makeup without stripping the skin of natural moisture or disrupting the acid mantle. This balance allows for effective cleansing while maintaining skin health. Conversely, a product that does not respect these pH levels may not cleanse as intended and could even lead to adverse reactions, such as dryness or increase the risk of infections.

In summary, pH is essential to how well a product cleanses the skin and supports its overall health.
