The Ordinary Lactic Acid 10% + HA High-Strength Exfoliating Serum For Uneven Texture
A high-strength exfoliator that works to reveal smoother skin.
Step 2: Treat
Lactic Acid 10% + HA is an alpha hydroxy acid solution that offers effective exfoliation targeted at the skin’s surface. It is supported with purified Tasmanian pepperberry extract, a known anti-irritant. 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 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 optimal balance between salt and acidity, optimizing the delivery of the acid form to ensure it provides an effective exfoliation that can be used daily.
