Coix Lacryma-Jobi Ma-yuen 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' Standard or Concentrated 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.

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.
This research shows the extract protects the skin barrier from surfactant-induced dryness by downregulating pro-inflammatory markers COX-2 and PGE2. This supports its use in formulating gentle cleansers and other products designed to maintain skin integrity.
The study confirms potent anti-pruritic and barrier-protective properties by demonstrating a significant suppression of histamine release and other irritation mediators. This validates its application in cosmetic products designed to improve comfort and soothe sensitive or compromised skin.
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.
