A healthy skin starts from the inside out. It is crucial to understand that the food we eat and the lifestyle we follow dramatically affect how healthy our skin is. Let’s be very clear, no one element is responsible for the health of our skin. Nonetheless, food and lifestyle are huge factors.
The acid mantle is our skin’s defense system, a very fine slightly acidic film produced in part by our outermost layer of skin (or the Stratum Corneum) where it contributes sebum (oils, waxes, esters) and sweat (water, salt). The acidity develops when the bacteria on our skin (don’t worry, this kind of bacteria is our friend, and he’s awesome!) breaks down these oils into fatty acids and glycerol. The average pH of the acid mantle of healthy skin is 5.5. Depending on your age, gender, skin type etc. this number can change.
