pH simply refers to how acidic or alkaline (basic) a substance is.
The pH scale ranges from 0.0 (acidic) to 14.0 (alkaline). A pH level of 7 is considered neutral. Your skins pH level is usually around 4.5 – 5.5 and is slightly more acidic. This is because acidity helps to fight harmful bacteria.
If this balance is disrupted, it will affect the acid mantle of the skin.
The acid mantle is a thin protective layer on the very outside of the skin. This is apart of the stratum corneum layer and is made up of sebum (lipids) and sweat. This mix is known as the acid mantle and acts as a barrier and defence system for the skin.
Everything we come in contact with can have the potential to harm and break down our acid mantle and the potential for the skin to protect itself.
The acid mantle protects the skin from bacteria, viruses, chemicals, pollutants and other microorganisms. If unbalanced pH levels disrupt this barrier, it will be extremely hard to have manageable skin.
If it is too far outside of 4.5 – 5.5 your skin may become inflamed, irritated, sensitive and dry. It may also contribute to skin conditions such as eczema, dermatitis and rosacea as well as acne. The skins process of generating new skin cells and shedding of the old will also be disrupted.
Certain skin care products you’re using may not be balanced and will be contributing to these factors daily without you knowing it. It’s always handy to check, which you can do by using pH tests found at a pharmacy.
It’s so important to have a healthy balance, as you want your skin to have the ability to heal, protect itself and keep in moisture for a naturally vibrant and healthy glow.
