    Lactic Acid 5% + HA

    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 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 the 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.

    - 30 mL / 1 fl. oz.

    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. 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 afterward.)

    Ingredients:
