Lactic Acid 5% + HA
A mild lactic acid superficial peeling formulation
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.
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 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 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. Do not use
on sensitive, peeling or compromised skin. 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. 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 possibility of sunburn. Use a
sunscreen, wear protective clothing, and limit sun exposure while using
