Lactobionic Acid for Lip Application: Concentration & pH

Lactobionic Acid is a Polyhydroxy Acid (PHA) known for its gentle exfoliating and moisturizing properties. While it can generally be used on the lips, it is important to use it with caution due to the sensitive nature of lip skin.

We recommend using Lactobionic Acid at a lower concentration, typically not exceeding 5%, as higher concentrations can cause irritation. It's always best to start with a very low concentration (e.g., 0.5-1%) and observe your skin's reaction before gradually increasing if needed.

For lip formulations, consider the overall pH of the product to ensure it is balanced and gentle enough for this delicate area.
