Ingredient Name: Citric Acid
What is it? Citric acid is an alpha hydroxy acid (AHA) derived from citrus fruits, such as lemons, limes, oranges, and grapefruits. It is used as a natural pH adjuster for cosmetic products to maintain a pH similar to the skin. The skin functions most optimally when the pH is balanced. Skin that’s too acidic or too alkaline can lead to irritating conditions like eczema, dryness, and acne
Why do we use it? We use it in the Mother of All Creams and our Scalp Therapy Shampoo as a natural way to balance pH and protect the skin barrier's function.
