Your skin has an acid mantle, which is actually a thin layer that protects your skin. Having a skin ph level less than or higher than 5.5 inhibits your body's ability to produce lipids, also known as fat. Lipids produced by your body maintain a healthy barrier against germs and other irritants that cause allergies and other skin conditions like acne and eczema and bacteria and organisms like staph and candida.

Let's take a look at how your skin's acid mantle functions to maintain your skin's health.

What Does Your Skin's Acid Mantle Do?

Your Skin's Natural Defense

Lipid Production

Your skin relies on its ability to produce lipids, or fats, to maintain a healthy barrier against irritants and germs. If your skin pH is higher than 5.6, the enzymes that create those lipids can’t function, leaving your skin dry and vulnerable.

Producing Antibiotics

Within your skin barrier, antimicrobial peptides are created that fight off bacteria and organisms like P. acnes, staph and candida. But they, too, can only function in a pH of 4.6-5.6. What’s worse is that all those bad bugs thrive in an alkaline pH, and all of them are associated with conditions like eczema, acne, rosacea, and intertrigo.

Preventing Inflammation

Slightly acidic skin pH inhibits inflammation. In fact, babies born with a genetic tendency for eczema may never develop an acid mantle, which leads to them developing eczema.

Resisting Allergies

Skin allergies are much more common in people with a skin pH that is too alkaline, which is why eczema patients are also much more likely to have skin allergies. (For instance, 24% of non-eczema sufferers develop nickel allergies, whereas 90% of eczema patients are allergic to nickel.

Sloughing Dead Skin

Your skin’s pH affects what is called “cellular differentiation”, or the process by which your skin changes the outermost skin cells to form a healthy and constantly-renewing barrier, which sloughs off as dead skin and is replaced. When your pH is too alkaline, it disturbs the amount of calcium in the skin layers, and that renewal process can’t function properly. Now that that's out.
