What is skin pH?
PH is a measurement of how acidic or alkaline (basic) a substance is in comparison to distilled water which is neutral. A neutral pH is 7.0, anything above is alkaline and anything below is acidic. The normal pH of your skin is around 4.5- 5.5, so slightly acidic. Skin tends to be in its healthiest state with a pH of less than 5.
The pH of the skin plays a role in maintaining the skin’s natural, healthy bacterial flora, AKA microbiome, and its natural protective barrier, AKA acid-mantle. The acid mantle is a thin layer on the skin’s surface made up of sebum combined with lactic and amino acids to create the skin’s pH. The acid mantle and microbiome of your skin protect you from invaders like bacteria, viruses, fungi, and pollutants. When your skin’s pH is chronically too high, you may experience more acne, rosacea and rashes. So, keeping your skin’s pH at an optimal level will not only protect you but also give you supple, beautiful skin.
The pH of your skin can be altered with exposure to substances like water, harsh skincare products, detergents, diet, infection and pollution. Water is the most altering substance that we are all exposed to on a daily basis. The water source that you use to wash your skin with usually has a pH of 8.5 or more depending on how hard it is. The other most common mistake we make is using harsh cleansers and skincare products. If you skin feels squeaky clean after cleansing, then your cleanser has a high pH and is disrupting the acid mantle.
By maintaining a healthy pH, your skin will not only be more radiant and supple, but more youthful and smooth.

Bioactive ingredients… Let’s talk about what makes skincare WORK!!!
Why does Skincare have to be so complicated?
All of us want beautiful and healthy skin. We want that youthful radiance to last us for years to come. And most of us continue to fall for marketing gimmicks that tell us THIS is the holy grail product so buy me now!! So we do!! Speaking from experience, it was the constant let down that I got from product after product that led me into my career field of aesthetic dermatology and aesthetics.
