Skin pH and barrier health guide for managing irritation

Maintaining the skin's natural pH balance is essential for a healthy acid mantle, which typically ranges from 4.5 to 5.5. This slightly acidic environment helps retain moisture and protect against germs. Disrupting this balance can lead to redness, irritation, dryness, and increased inflammation. Research indicates that skin with a pH below 5 often exhibits better moisture retention and stronger barrier measurements, whereas higher pH levels are associated with conditions like acne and atopic eczema.

When the skin barrier is compromised, individuals may experience stinging, tightness, or flaking. To support barrier repair, experts recommend using products containing lipids such as ceramides, cholesterol, and fatty acids, as well as humectants like hyaluronic acid and glycerin. Soothing agents like panthenol and colloidal oatmeal can also help calm sensitivity. Recommended products for rebuilding the barrier include the Innisfree Green Tea Ceramide Cream and CeraVe Moisturizing Cream.
