Lactic Acid 10% + HA
The Ordinary Lactic Acid 10% + HA is an alpha hydroxy acid that exfoliates the skin. This 10% formulation 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. A milder 5% formula is available here.
The Ordinary Lactic Acid 10% + HA's 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.
Review(s) on The Ordinary Lactic Acid 10% + HA:
"Love the 10% lactic acid! My skin so dewy and glows! It has helped significantly with skin congestion and acne, without drying out the skin. I like the light texture and don't mind the "runny" formula, I like how it glides on nicely and absorbs well." -AG's review of The Ordinary Lactic Acid 10% + HA 2% from theordinary.com
"Applied on my inner cheeks as the first step after cleansing (the spots where I have very large pores that are visible even under silicone primer), lactic acid has dramatically reduced the look of my pores. It hasn't dried me out either. Thank you!" -JL's review of The Ordinary Lactic Acid 10% + HA 2% 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.

Best lactic acid i have ever tried.
Acids are not very new to me for i’ve been dealing with them for quite some time now to address my skin concerns. Despite that, it’s my first time trying out Lactic Acid. Over the brief span of time that i’ve used it, it hasn’t given me any drastic effect yet however, i could say that it contributed to my skin’s brightening and refined texture. I am yet to see if it is effective in diminishing hyperpigmentations and other flaws.
If you're just starting out with chemical exfoliatora, you should probably try the 5% Lactic Acid variety. It has a smell that i never got used to.
