Exfoliating Serum 30 ml

Our Acide Lactique 10% + HA solution, based on alpha hydroxy acid, provides effective exfoliation targeted at the skin's surface. It is combined with purified Tasmanian pepper extract, which has been proven effective in addressing the feeling of irritation and sensitivity sometimes associated with the use of acids. This water-based serum is ideal for dry skin. The pH of this formula is approximately 3.8. Lactic acid has a pKa of 3.8. The pKa is the most important aspect to consider in acid-based formulas, as it indicates the availability of acids. When the pKa is close to the pH, the salt balance is ideal, optimising the acid's effectiveness and reducing the sensation of irritation. Show less
