Usnic Acid: Lichen-Derived Active for Deodorizing, Sebum-Regulating and Purifying Formulations

Molecular Identity

• INCI Name: Usnic Acid
• Molecular Formula: C₁₈H₁₆O₇
• Source: Extracted from lichen species such as Usnea barbata

Function & Application

Usnic Acid is a naturally occurring dibenzofuran compound derived from lichens, used in cosmetic and personal care products for its purifying and odor-neutralizing properties. Due to its molecular characteristics, it is particularly suitable for formulations aimed at oily skin, scalp regulation, or body freshness systems.

• Deodorizing Action: Frequently included in deodorant systems and freshness-enhancing body care
• Sebum Regulation: Applied in facial and scalp formulations to manage oil balance
• Natural Origin: Aligns with clean beauty and bioactive positioning
• Microbiome-Conscious: Used in low concentrations to support formulation hygiene without disrupting skin flora

Used in oil-control emulsions, deodorizing gels, scalp tonics and purifying cleansers. Supplied in bulk format with full B2B documentation.

Typical Usage & Handling

• Deodorant creams or sprays: 0.01–0.2%
• Scalp and facial care: 0.02–0.1%
