Semen Coicis Extract (Job's Tears/Coix Seed Extract), a scientifically validated botanical active ingredient that offers a comprehensive solution for modern skincare challenges. Rooted in traditional Asian medicine, this extract is now supported by contemporary research for its potent efficacy in moisturizing, brightening, soothing, and balancing the skin.

1. Hydration and Barrier Support

Semen Coicis Extract is a powerful humectant. Clinical studies demonstrate that formulations containing this extract significantly improve skin hydration for over six hours, outperforming standard moisturizing bases . This superior moisturizing effect helps reinforce the skin’s natural barrier function, preventing transepidermal water loss and maintaining long-term skin health .

2. Brightening and Anti-Aging

The extract exhibits notable antioxidant properties and a significant inhibitory effect on tyrosinase, a key enzyme in melanin production . Research shows that a 1 mg/mL concentration of the extract can inhibit human tyrosinase activity by up to 50.7%, demonstrating a clear efficacy in reducing melanin content and fading hyperpigmentation . Furthermore, its rich content of phytosterols and polyphenolics combats oxidative stress, contributing to a reduction in wrinkles and promoting a more youthful complexion .

3. Soothing and Sebum Regulation

Ideal for sensitive and acne-prone skin, Semen Coicis Extract provides anti-inflammatory benefits. In vivo studies on atopic dermatitis models have shown that topical application reduces skin lesion severity, lowers serum IgE and IL-4 levels, and significantly decreases mast cell infiltration, confirming its efficacy in calming irritation and redness . Concurrently, it regulates sebaceous gland activity, reducing excess oiliness and refining skin texture without compromising hydration .
