The Ordinary Lactic Acid 10% + HA



The Ordinary Lactic Acid 10% + HA is a high-strength lactic acid superficial exfoliating formulation.

Why We Love It

This exfoliating serum uses lactic acid and other humectant ingredients to draw moisture into the skin whilst sloughing off dead skin cells overnight. 

 The Ordinary Lactic Acid 10% + HA

Lactic Acid 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.

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.


Apply 1-3 times per week, ideally in the PM to clean, dry skin. Can be diluted with other treatments to reduce strength until skin develops tolerance.


Massage 2-3 drops into skin. Leave on skin - do not rinse off. Do not use on sensitive, peeling or compromised skin. Avoid contact with eyes. Use only as directed on unbroken skin. Patch testing prior to use is advised.


Continue with additional skin treatments as needed.


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.

Sodium Hyaluronate Crosspolymer

A modified form of skin-replenishing hyaluronic acid attached to a polymer structure that keeps it within skin’s uppermost layers longer, allowing for enhanced hydration.

Lactic Acid

Exfoliates surface layers of skin by breaking down the material that holds dead skin cells together, allowing it to shed naturally as it once did. Lactic acid may cause sensitivity, although this isn’t common and can be minimised/eliminated if the formulation contains soothing ingredients (as this one does). Helps brighten and even skin tone.
