PH of Skin

Skin is a multi-tasker, performing several roles for our overall well-being. The most important role it plays is as a protective barrier between our bodies and the outside world, and skin’s pH is one of its key protective mechanisms.

The pH of our skin is constantly challenged by external aggressors such as pollution, and chemicals. Some skincare products can help maintain skin’s optimal PH. This makes skin more resilient and better able to carry out its important work. The optimal pH value of skin on most of our face and body lies between 4.7 and 5.75. A pH of 7 (that of pure water) is considered neutral. so skin’s natural pH is mildly acidic.

There are many external factors that may have an impact on skin’s PH.
Frequent washing in water that is too hot, can stress skin.

The external factors that stress skin include:

• Changes in temperature and humidity
• Chemical exposure
• Dirt and pollution

Other factors that can affect skin pH include:

Acne

Antibacterial products

Change in seasons, with different humidity levels

Cosmetics

Detergents

Antibacterial soaps and gels

Sebum/skin moisture

Sweat

Substances with an alkaline pH can be detrimental to skin’s pH. They may overtax skin’s natural neutralizing capability and impair the skin’s protective moisture barrier.

Skin’s pH plays an important role in the skin’s barrier function. If skin’s pH rises into the alkaline range, its natural balance is disturbed. This could lead to compromising skin’s barrier function, and water loss from the skin.

When skin’s barrier function is compromised, it is less resilient and more sensitive to environmental triggers. It can become dry or sensitive

Skin pH is just one of the aspects in overall skin health. Taking care of your skin with a cleanser and moisturizer for your skin type helps strike the right balance of oil your skin needs to stay at its healthiest.
