Lactic Acid 5% + HA
The Ordinary Lactic Acid 5% + HA is a Mild Lactic Acid Superficial Peeling Formulation
Lactic Acid is an alpha hydroxy acid that exfoliates the skin. This 5% formulation offers very mild exfoliation and is supported with a purified Tasmanian pepperberry known to reduce signs of inflammation and sensitivity that is often associated with exfoliation. A stronger 10% formula is available here.
This formula contains a studied Tasmanian Pepperberry derivative to help reduce irritation associated with acid use. This derivative is of plant origin and varies in colour seasonally and this colour variation may be apparent in the formula from time to time.
Contraindications: 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.
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.
Note: While Lactic Acid can result in quick visible benefits, we generally suggest indirect forms of skin exfoliation in favour of direct forms such as this formula due to potential inflammation and sensitivity associated with acids. Please refer to NIOD's Non-Acid Acid Precursor for such a reference.

"The Lactic Acid 5% + HA has been a total game changer for my skin! I have combination skin and use this at night. My skin is so soft and clear in the morning. I'll be re-purchasing this for life! My #1 favorite product from The Ordinary!" -JB's review of The Ordinary Lactic Acid 5% + HA from theordinary.com
"After 3 applications I can say that this stuff works fast! I tend to have sensitive skin but wanted to try something as my skin was looking dull more often than not. This changed that after 2 treatments! I use it every other day and my skin just looks better." -TL's review of The Ordinary Lactic Acid 5% + HA from theordinary.com
The Ordinary's formulations are updated from time to time as part of their commitment to innovation. As such, the ingredient list shown here may vary from the box of the product depending on time and region of purchase.
Lactic Acid has a natural odour that some people find unpleasant. This formula was updated in October 2017 to use a grade of lactic acid that has no odour per customer feedback. Additionally, this update removed the use of carrageenan, a seaweed-based viscosity-enhancer, also due to feedback from customers. These changes improve the sensory aspects of the formula but do not impact efficacy.
