Why is pH so Important for Better Skin?
Working With Your Skin's Nature
Your skin's natural pH levels are normally in the acidic level on a scale, and is naturally at an average of about 5.5, which is leaning towards being slightly acidic.
As we age, our skin’s acid mantle starts to become more alkaline, which means that the pH level starts creeping higher. The more alkaline the skin’s natural pH level, the weaker the skin’s acid mantle is.
Why is that important?
Your Skin’s Acid Mantle
The acid mantle is the first layer of defense for your skin’s microbiome. Sudden changes in your skin’s pH levels have the ability to impact your skin’s microbiome. When your skin becomes too alkaline, it’s an environment where the bad bacteria in your microbiome have the ability to thrive, grow, and disrupt the balance of good to bad bacteria.
The Secret to Managing Aging Skin
Keeping your skin healthy and strong will help reduce the visible signs of aging, slow down the process, and even reverse some of the signs as you help restore your skin’s naturally occurring functions.
The Promise of Probiotics in Skincare for Aging Skin
The use of probiotics in skincare is useful for restoring your skin’s acid mantle “due to the fermentative metabolism that involves the production of acid molecule, thus acidifying the surrounding environment.” 
Additionally, probiotics will help reduce some of the cellular activity that is attributed to breakdown of your skin’s collagen which is one of the main causes for lines, wrinkles and decreased volume and firmth. The anti-inflammatory mechanisms of probiotics show that they are ultimately a very promising treatment in the field of anti-aging skincare, which is constantly evolving as we continue to learn more about our skin’s microbiome.
