The extract

The Multi-Functional Science of Coix Seed Extract

Coix Lacryma-Jobi Ma-yuen Seed Extract, also known by its common names Job's Tears, Adlay, or simply Coix Seed, is a time-honored botanical revered in traditional beauty practices. Formulate Labs supplies this premium active strictly under its INCI designation, ensuring chemists receive the precise botanical identity for consistent formulation and reliable performance, rather than generic supplier SKUs or various trade names.

Dual mechanism: Coix Lacryma-Jobi Ma-yuen Seed Extract provides comprehensive skin benefits through two key pathways. Primarily, its bioactive coixol acts as a competitive tyrosinase inhibitor, effectively interrupting melanin synthesis to visibly reduce hyperpigmentation and brighten overall skin tone. Concurrently, the extract leverages its rich concentration of polysaccharides, phytosterols, and flavonoids to deliver significant moisture retention, support the epidermal barrier, and neutralize oxidative stress, resulting in a soothed and more resilient complexion.

Use levels: — For Formulate Labs' 5% hydroglycerin stock, incorporate 2.0% – 3.0% into standard emulsions, toners, and serums to achieve optimal cosmetic efficacy.

Market context: — Coix Seed Extract is a cherished "Hanbang" active heavily featured in K-Beauty and J-Beauty for addressing impaired skin barriers, dullness, and hyperpigmentation. It is also positioned as a clean, plant-derived alternative to synthetic brightening agents, meeting consumer demand for non-irritating ingredients. Furthermore, it serves as a synergistic formulation enhancer, commonly combined with ceramides, niacinamide, and fermented filtrates in premium formulations for sensitive, acne-prone, or aging skin profiles.

Pricing context: — Public pricing data for pre-solubilized hydroglycerin or propanediol-based Coix seed extracts is limited. Formulate Labs offers a transparent B2B price ladder for our solubilized, value-added extract, with a 500g sample priced at $78.00, 1kg at $120.00, and a 17kg pail at $1,632.00 (equivalent to $96.00/kg), reflecting its value as a specialized cosmetic active.

Published research

Peer-reviewed literature for due diligence.

The cosmetic efficacy of Coix Lacryma-Jobi Ma-yuen Seed Extract is rigorously supported by peer-reviewed literature, validating its multi-functional benefits in skin care. Studies confirm its role in barrier protection, anti-pruritic activity, and significant skin brightening through distinct mechanisms. These are independent, third-party papers we link for formulators evaluating mechanism, tolerability, and published panel data. We did not conduct this research and do not guarantee replication in your finished formula.

None

See journal record

This paper confirms that the bioactive coixol is a strong melanogenesis inhibitor that disrupts the tyrosinase pathway without being cytotoxic to melanocytes. This highlights the extract's value as a non-irritating ingredient for visibly improving skin tone and reducing hyperpigmentation.
