Directions:

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

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 is 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 colour seasonally and this colour variation may be apparent in the formula from time to time.

-----

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.
