Lactic Acid is an alpha hydroxyl acid that exfoliates the skin. The Ordinary Lactic Acid 10% + HA offers mild exfoliation and is supported with a purified Tasmanian pepperberry known to reduce signs of inflammation and sensitivity that is often associated with exfoliation.
The Tasmanian Pepperberry derivative helps to reduce irritation associated with facial acid use, including alpha-hydroxy acids such as lactic acid. Please note that Tasmanian Pepperberry varies in colour seasonally, and this colour variation may be apparent in The Ordinary Lactic Acid 10% + HA.
When to not use The Ordinary Lactic Acid 10% + HA: Lactic Acid should not be used on sensitive, peeling or compromised skin. Please refer to additional sun protection note and other warnings in provided Directions. Ensure that this formula is introduced slowly into your routine.
This pH of this formula is approximately 3.8. Lactic Acid has a pKa of 3.8 and pKa is the most important aspect to consider in formulating with acids. pKa implies acid availability. When pKa is close to pH, there is an ideal balance between salt and acidity, maximizing effectiveness of the acid and reducing irritation. Higher pH numbers in such a case would increase salt which counter-intuitively would make the formula even more irritating than if the formula was more acidic.
