Lactoperoxidase

What Lactoperoxidase is & what it does

An enzyme with natural antimicrobial activity that helps protect the formula and support a balanced skin surface. It is gentle and multifunctional.

Is Lactoperoxidase safe?

Lactoperoxidase is an enzyme used in some cosmetics, often as part of a natural preservation or antimicrobial system, and is generally considered safe at the levels used. As with any protein-based ingredient, sensitive skin may want to patch test. For specific concerns, consult a qualified professional.

What does Lactoperoxidase do in skincare?

Lactoperoxidase is an enzyme that helps support a formula's preservation or antimicrobial system, often paired with other components in a natural preservative blend. It works through enzyme activity rather than as an active skincare treatment. In a sunscreen it would play this supporting role rather than acting as a UV filter.

Is Lactoperoxidase vegan?

Lactoperoxidase is an enzyme that is traditionally sourced from milk, so it is typically of animal origin and is generally not considered vegan. Some versions may be produced by other methods, so if vegan status matters, it is best to confirm the source with the brand.
