The Ordinary - Lactic Acid 5% + HA 2%

 Lactic Acid is an alpha hydroxyl acid that exfoliates the skin.

The Ordinary Lactic Acid 5% + HA 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.

 The pH level of this formula has been carefully adjusted to -3.8 to maximize the efficacy and reduce signs of redness and sensitivity.

Key benefits of The Ordinary Lactic Acid 5% + HA 2%

When to not use The Ordinary Lactic Acid 5% + HA: 

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. Ensure that this formula is introduced slowly into your routine.

The 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 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.

Conflicts: Do not combine with other strong acids, EUK 134 0.1% or Peptides.
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.

Contact of the product with the skin must be of limited frequency or duration - we recommend 2 to 3 times a week.

If irritation occurs, cease use and consult a physician.

Use only as directed on unbroken skin.

Patch testing prior to use is advised.

Keep out of reach of children.
