THE ORDINARY Lactic Acid 10% + HA - 30ml

Lactic Acid is an alpha hydroxy acid that exfoliates the skin. This 10% formulation offers mild exfoliation and is supported with a purified Tasmanian pepper berry known to reduce signs of inflammation and sensitivity that are often associated with exfoliation. A milder 5% formula is available here.

This formula contains a studied Tasmanian Pepper berry 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.

Contraindications: Lactic Acid should not be used on sensitive, peeling or compromised skin. Please refer to the additional sun protection note and other warnings in provided Directions.

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.
