Why your skin pH is important?

pH is a scientific term that describes how acidic or alkaline a substance is. The range of pH varies from 0-14, lower the number is, the more acidic the substance is. Water, which is considered as neutral, has a pH of 7. Our skin is slightly acidic, with a pH range between 4.7 and 5.75 varies from body sites to body sites. In addition, pH increases slightly with age, females have lower skin pH value compared to male, deeper skin has more acidic skin than white skin. 

Due to the acidic nature of skin, there is a very thin layer of natural oils (sebum produced by your sebaceous gland), amino acids and sweat on the uppermost layer of the skin called acid mantle. It acts as a barrier to protect the skin from bacteria, viruses and other contaminants from the external environment. 

When the pH of your skin changes undesirably, acid mantle will be disrupted leading to dehydration, acne, inflammation and/or other skin disorders. Damaged acid mantle is not always permanent, for the most of time, it can repair itself in a couple of weeks. 

Because of the natural acidity, skin is compatible with acidic skin care products.  Therefore, check out for pH-balanced skin care products is essential to your skin care regimen. Most products on the market fall to the pH range of 4 - 7, except for products containing AHA/BHA. These products are designed to have a pH between 3 - 4 to provide extra benefits like exfoliating properties. Skin naturally equalizes to its normal pH for temporary pH changes, therefore, for exfoliating products, we recommend applying them once or twice a week.
