What is pH?

In chemistry, the pH (potential of Hydrogen) is a measure of acidity and alkalinity. The pH scale ranges from 0 to 14, with 7 being neutral (neither acidic nor alkaline). Anything under 7 is acidic. Anything above 7 is alkaline (or basic).

pH of Common Items
* Lemon Juice pH 2.0. * Vinegar pH 3.0. * Water pH 7.0 (neutral). * Baking Soda pH 8.0. * Soap pH 8.0-11.0. * Ammonia pH 12.0.

The pH of the skin is one of the most important things to understand about healthy skin care.

Healthy skin has a pH of around 5.0 - 5.5 (which is slightly acidic)

This is an average, but can range from 4.5-6.5 depending on your skin chemistry, the products you have been using on your skin and indeed what you have in your diet.

Acidity plays a key role in healthy skin

Certain enzymes in the Stratum Corneum are activated at an acidic pH. Changes in pH affect enzyme activity and interfere with the skin’s normal shedding process (desquamation), which is why maintaining the correct pH of your skin is essential for healthy skin.

Additionally, an acidic pH inhibits the growth of certain harmful bacteria on skin.

The Acid Mantle Protects Skin.

The Stratum Corneum (the outermost layer of the epidermis) is a protective barrier to the external environment.

The combination of sebum and perspiration forms a film on top of the Stratum Corneum known as The Acid Mantle. It is both a physical and chemical barrier that provides a crucial form of protection, the skin’s first line of defence.

If it is disrupted or removed, skin becomes more permeable to microorganisms (such as bacteria), harsh chemicals, and pollutants. In addition, water escapes from skin at a quicker rate. You may often here someone say “I want to protect my acid mantle” that’s because it’s easily bothered (over exfoliation is a prime example or using products with the wrong pH).

As our skin is naturally acidic, it’s important that we apply products that are consistent with our skins natural pH (ie. acidic).

All of the Skinlabs Direct products are purposely acidic to protect the skin’s outer layer.

Skin care for all ages and skin conditions.
