Science
Mechanism of Action
This ingredient forms an immediate, elastic micro-film upon application, resulting in a perceptible skin tightening and micro-lifting effect. It enhances skin texture through moisturizing and toning properties, yielding a smoother, more rehydrated complexion. Rich in vitamins B2 and C, alongside critical amino acids like L-lysine and L-proline, it actively supports skin health and the body's natural collagen production pathways. Functioning as a potent antioxidant, it neutralizes free radicals, provides defense against UV radiation and environmental pollutants, and rejuvenates skin cells to combat signs of aging. Certain antioxidants within the juice may boost localized blood flow to minimize scar appearance, while others offer anti-inflammatory benefits, potentially reducing acne and fine lines by enhancing cell metabolism and microcirculation. It also strengthens the skin barrier and possesses soothing attributes, making it suitable for sensitive skin by mitigating inflammatory processes. When fermented, its efficacy is amplified, demonstrating the ability to promote fibroblast proliferation, inhibit the gene expression of TIMP-1 and Tropoelastin, reduce MMP-1 activity, and suppress tyrosinase activity and melanin synthesis, collectively contributing to enhanced anti-wrinkle and skin brightening effects.

Clinical Evidence
Medium confidenceN/A
Key findings
- 01 A 50% ethanol extraction of sorghum seed extracts demonstrated antimelanogenic and anti-wrinkle potential, evidenced by significant antioxidant capacity, antityrosinase activity, and the suppression of matrix metalloproteinase (MMP)-1, -2, and -3 protein expression in human neonatal foreskin HDF-N cells. Fermentation with Aspergillus oryzae NK further enhanced these cosmeceutical benefits.
- 02 Enzymatically derived kafirin peptides from white sorghum (fractions <1 kDa and 1-3 kDa) exhibited significant protective effects on human skin cell cultures exposed to UVB radiation. These included a reduction in oxidative stress, suppression of pro-inflammatory cytokines (IL-1β, TNF-α, IFN-γ), and inhibition of photoaging-associated enzymes such as elastase, collagenase, and tyrosinase.
