Lactic Acid is an alpha hydroxy acid (AHA) that offers superficial exfoliation to enhance smooth skin texture and radiance. This formula is supported by the addition of purified Tasmanian pepperberry extract to offer a comforting benefit to the skin in effort to reduce sensitivity that is associated with acid use. The formula is further supported with the inclusion of hyaluronic acid for multi-depth hydration. A milder 5% formula is available here.
This pH of this formula is approximately 3.8 and Lactic Acid has a pKa of 3.8. The pKa value is the most important aspect to consider in formulating with acids as pKa implies acid availability. When pKa is close to pH, there is an ideal balance between salt and acidity, maximizing the efficacy of the acid and reducing the potential of developing irritation. Higher pH values in such a case would increase the concentration of salt, which counter-intuitively would make the formula even more irritating than if the formula was more acidicContraindications: Lactic Acid should not be used on sensitive, peeling or compromised skin.

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.Notes: 1. The Tasmanian Pepperberry derivative included in this formula is of plant origin and as such will vary in colour seasonally. This colour variation may be apparent in the formula from time to time.
2. While exfoliating acids can result in quick visible benefits, we generally suggest indirect forms of skin exfoliation for a gentler approach. Please refer to NIOD's Non-Acid Acid Precursor for such a reference.

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. If irritation persists, discontinue use and consult a physician. (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 this product and for a week afterwards.)
