Understanding Skin pH for a Healthy Glow
Learn what your skin's pH is and why maintaining its natural acidity is crucial for a healthy, radiant complexion and a strong skin barrier.
What is it?
The pH of skin refers to its acidity level. Measured on a scale from 0 (most acidic) to 14 (most alkaline), healthy skin is naturally acidic, with an optimal pH between 4.7 and 5.75. This acidity is maintained by the "acid mantle," a thin, protective film on the skin's surface composed of natural oils, sweat, and ceramides. This barrier is the body's first line of defense against external aggressors like harmful bacteria, pollution, and allergens. A balanced pH is essential for the skin's protective barrier to function correctly, retain moisture, and keep its microbiome in harmony.
Why is it trending?
The concept of skin pH is gaining traction as consumers become more educated about skincare ingredients and the science behind them. There's a growing understanding that a compromised skin barrier is the root cause of many skin issues, including dryness, sensitivity, and acne. Using products with a pH that is too alkaline (like many bar soaps) can strip the skin's natural oils and disrupt the acid mantle. This disruption can lead to increased dryness, irritation, and vulnerability to damage. Consequently, the beauty industry is emphasizing "pH-balanced" products designed to work in harmony with the skin's natural state.
How does it affect people?
An imbalanced skin pH can lead to noticeable skin problems. If the pH becomes too alkaline, the skin can lose water and dry out, leading to tightness, flakiness, and increased sensitivity. This state weakens the skin's protective barrier, making it more susceptible to conditions like eczema and rosacea. Conversely, if the skin becomes overly acidic, it may result in redness and irritation. To maintain a healthy pH, it's recommended to use gentle, pH-balanced cleansers, avoid harsh scrubs, and moisturize regularly to support the skin's natural barrier.
