If it’s too acidic, you’ll increase your chances of inflammatory skin conditions like eczema and acne.”

How can pH affect human being?

pH of Different Body Fluids Although the pH of blood ranges from 7.35-7.45, the pH of other body fluids is different. pH indicates the level of H+ ions, where low pH indicates too many H+ ions and high pH indicates too many OH- ions. If the pH levels drop below 6.9, it can lead to coma.

Why is pH important for skin?

Skin’s pH plays an important role in skin condition. The acid mantle is key to skin’s protective barrier. It neutralises alkaline-based aggressors (such as harsh surfactants), inhibits the growth of bacteria and restores and maintains the optimal acid environment in which skin’s natural flora can thrive.

Is low pH water bad for your skin?

As the surface of your skin is slightly acidic, increases in pH have been found to have a dehydrating and irritating effect on the skin. Research has also shown that several inflammatory skin diseases, such as eczema, are often accompanied by a rise in pH ( 20 , 21 ).

What does pH of skin mean?

The pH level of the skin refers to how acidic or alkaline it is. This acid mantle is made up of sebum (free fatty acids) excreted from the skin’s sebaceous glands, which mixes with lactic and amino acids from sweat to create the skin’s pH, which ideally should be slightly acidic – at about 5.5.

What is pH level in skin care?

pH stands for potential hydrogen and is a measure of how acidic or alkaline a substance is. For your skin to remain balanced, your acid mantle will naturally stay slightly acidic with a pH of around 4.5-5.5. This can be thrown off by anything from UV rays, humidity and skincare products.

Is there a unit for pH?

pH is a logarithm (the negative of the logarithm of H+ activity), and as such it has no unit.
