The Ordinary Lactic Acid 5% + Ha 2% Serum

Lactic Acid 5% + HA is a gentle alpha hydroxy acid solution that provides effective exfoliation targeting the skin's surface. 

A milder exfoliator that works to reveal smoother skin!

This water-based serum is fortified with purified Tasmanian pepper berry extract, which has been demonstrated to alleviate the irritation and sensitivity that can accompany the use of acids. 

With a pH of approximately 3.8, this formula is particularly suitable for individuals with dry and sensitive skin. 

When pKa is close to pH, there is an optimal equilibrium between salt and acidity, maximizing the acid's effectiveness while minimizing irritation.

Use after cleansing and water-based serums, before oils, suspensions, or creams.
