A High-Strength Lactic Acid Superficial Peeling Formulation. Lactic Acid is an alpha hydroxyl acid that exfoliates the skin. This 10% formulation offers 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 milder 5% formula is available here.

More Product Information

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, maximising 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.

Great product

I mix this with The Ordinary's Buffet, to avoid the tingling sensation. I have very sensitive skin, so this hasn't been an issue for me.

Works very well on acne-prone skin with another serum

Never use this alone because it will be too drying. But combining it with another hydrating/anti-aging serum can do wonders.
