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 is often associated with exfoliation. A milder 5%
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.
Contraindications: 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.
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.
Note: While Lactic Acid can result in quick visible benefits, we
generally suggest indirect forms of skin exfoliation in favour of direct
forms such as this formula due to potential inflammation and
sensitivity associated with acids. Please refer to
NIOD's Non-Acid Acid Precursor for such a reference.
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. 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.
Sunburn
Alert: This product contains an alpha hydroxy acid (AHA) that may
increase your skin's sensitivity to the sun and particularly the
