THE ORDINARY Lactic Acid 5% + HA - 30ml

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 are 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 color seasonally and this color variation may be apparent in the formula from time to time.

When pKa is close to pH, there is an ideal balance between salt and acidity, maximizing the 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.

Apply once per day, ideally in the PM. Can be diluted with other treatments to reduce strength until the skin develops tolerance.

Avoid contact with eyes. Contact of the product with the skin must be of limited frequency or duration. If irritation occurs, cease use and consult a physician.

Use only as directed on unbroken skin. Patch testing prior to use is advised. Refer to our in-depth guide to patch testing. Keep out of reach of children.
