Levulinic Acid

What Levulinic Acid is & what it does

A plant-derived preservative and skin-conditioning acid, often paired with sodium levulinate for natural preservation. It also adds light hydrating benefits.

Is Levulinic Acid safe?

Levulinic Acid is considered safe for use in cosmetics at the concentrations normally used, where it serves as a mild acid and part of preservative systems. It is generally well tolerated on the skin. As with any acid, very sensitive skin may prefer to patch test first.

What does Levulinic Acid do in skincare?

Levulinic Acid is mainly used to adjust and buffer a product's pH and to support its preservation, often paired with sodium levulinate. It also has some skin-conditioning properties. It is typically present in small, functional amounts rather than as an active treatment.

Is Levulinic Acid natural or synthetic?

Levulinic Acid can be produced from plant-derived sugars and starches, which is why it is sometimes described as nature-derived. The grade used in cosmetics is made through industrial processing of these raw materials. The final ingredient is the same compound regardless of source.
