How does pH affect skin care products?

pH plays a crucial role in determining how compatible a product is with the skin. The skin has a natural acidity, usually within a pH range of about 4.5 to 5.5, which helps maintain its barrier function and overall health. When skin care products have a pH level that is significantly different from that of the skin, they can cause irritation, disrupt the skin's natural barrier, and affect the overall skin microbiome.

Products that are too alkaline can strip the skin of essential oils and disrupt moisture levels, leading to dryness and sensitivity. On the other hand, products that are too acidic could also irritate the skin and lead to issues such as inflammation or an impaired barrier. Therefore, understanding and formulating products within an appropriate pH range is vital for ensuring they work harmoniously with the skin, maximizing efficacy, and minimizing adverse reactions. This compatibility is what makes the connection between pH and skin care products particularly significant.
