The Ordinary Lactic Acid 10% +HA 2%
Lactic Acid is an alpha hydroxyl 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.
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.
Apply once per day, ideally in the PM. Can be diluted with other treatments to reduce strength until skin develops tolerance. Avoid contact with eyes. If irritation persists, discontinue use and consult a physician. (Sunburn Alert: This product contains an alpha hydroxy acid (AHA) that may increase your skin's sensitivity to the sun and particularly the possibility of sunburn. Use a sunscreen, wear protective clothing, and limit sun exposure while using this product and for a week afterwards.)

I love that this hasn't caused me any irritation. It has left my skin glowing, smoother and lines are minimized. In fact people have been asking me if I have had botox or fillers done recently. NOPE! Its just The Ordinary's Skincare.
I am so in love with these products and my skin has never looked better.
started with the Ordinary’s Lactic Acid 5% but quickly moved on to
their 10% so I could see more results. The 5% worked better for skin
conditioning, whereas the 10% had more of an overall profound effect
on texture, pigmentation, and glow. I alternate between the two
frequently and I’m so grateful to have options! It’s
irritating than glycolic acid, it also hydrates, increases natural
barrier lipids in the outer layer of skin, and lightens and brightens
the look of skin for those with discoloration.
10% lactic acid would be better for experienced AHA users. It can
cause extreme sun sensitivity and if used too frequently, actually
damage your skin. As long as you’re careful though, this product is
amazing. It gives me a dewy glow like nothing else!
