Everything You Need To Know About Your Skin's pH
By OANA MURESAN
Define pH
The term “pH” stands for “potential of hydrogen” and measures the activity of the hydrogen ions in a water-based solution. We use pH to measure the acidity or alkalinity and it is used throughout the fields of agriculture, biology, chemistry, and even the skincare field.
Skin pH
Because our skin is made of 64% water it has a pH measurement. Our skin rests in the acidic range starting at 7 when we’re born and dropping as we age. Experts state that we should aim for a 'weakly acidic' pH for our skin with a pH level of around 5.5 being the ideal target.
Acid Mantle
Your skin's pH is calculated based on your acid mantle which is the very thin film on the top of your epidermis that’s a combination of sebum, the natural oil secreted by sebaceous glands, and sweat. There are both internal and external factors that can disrupt the composition of the acid mantle and cause problems for our skin.
pH Fluctuations
Some warning signs of pH fluctuation include dryness, itchiness, breakouts, and tight or sensitive skin, and can also mean that your acid mantle has been damaged or destroyed. Furthermore, people with a high pH balance (high alkaline) are more likely to develop more fine lines and crow's feet than those with acidic.
External Factors
Pay attention to what your skin comes into contact with on any given day and discard products (cleansers, detergents, beauty products, etc.) that are throwing off your pH. Environmental triggers, like pollution, are more difficult to address, but hydrating your skin if you live in an overly dry area or using SPF to avoid UV damage can help.
