Ordinary Lactic Acid 10% + HA

Regular price $6.70 $0.00

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.

Contraindications:

Lactic Acid should not be used on sensitive, peeling or compromised skin. 
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.

Directions

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.
