The acid mantle is a thin oily film, made up of sweat and sebum, which sits on top of the outmost layer of our skin and protects skin from bacteria entering. Many of the contaminants that might enter our skin, such as chemicals from the atmosphere and harmful bacteria, are alkaline in nature, which means they have a pH of higher than 7. When bacteria are killed by acid they can’t damage the skin but if you strip skin of its acidic mantle by using it becomes much easier for bacteria to find its way in. Our skin’s natural acidity neutralizes chemicals and bacteria, which is a necessary part of the body’s defense system.
The acid mantle becomes unbalanced with the use of strong alkaline soaps, cleansers and detergents. Excess perspiration may also be a factor. If you perspire more than average, your acid mantle will have a higher proportion of sweat compared to others, throwing skin of its natural balance.
Maintain skins acid mantle by:
- Using pH balanced skin care products
- Avoiding harsh soaps
- Frequently moisturizing with a slightly acidic moisturizer
- Protecting yourself from the sun
Maintaining both the acid mantle and skins pH is a fine balance, but vital to being able to neutralize harmful bacteria, which can lead to acne, infection, or irritation. pHisoderm Cleansers restore skin back to its natural balance to help maintain healthy looking and feeling skin.
