What significance does pH have in skincare?

pH is crucial in skincare because it directly influences skin barrier function and overall skin health. The skin has a natural pH level, typically around 4.5 to 5.5, which is acidic. This acidity helps maintain the skin's protective barrier, known as the acid mantle. When products have a pH that is too high (alkaline) or too low (too acidic), it can disrupt this delicate balance, leading to issues such as dryness, irritation, or increased susceptibility to infections.

A skincare product with an appropriate pH level helps to support the skin's natural defenses, ensuring that it retains moisture and remains protected against environmental stressors. Maintaining the proper pH in products is essential for promoting healthy skin function, efficacy of active ingredients, and overall skin appearance. Therefore, understanding the significance of pH in skincare is vital for making informed choices about products and their potential effects on the skin.
