    GlossarySkin pH (skin acidity)

    Skin pH, also known as skin acidity, refers to the measure of how acidic or alkaline the skin's surface is. Typically, healthy skin has a slightly acidic pH, ranging from 4.5 to 5.5, which helps maintain the skin's barrier function, protect against harmful bacteria, and support the natural microbiome. This balance is crucial for overall skin health and can be influenced by factors such as skincare products, environmental conditions, and individual health.
