Science
Mechanism of Action
As a specific type of oligosaccharide, Nigero oligosaccharides are expected to act as prebiotics on the skin. This involves selectively promoting the growth of beneficial resident skin microorganisms while simultaneously inhibiting the proliferation of pathogenic bacteria. They also function as humectants, attracting and binding water molecules to the skin, thus improving hydration. Beyond these primary actions, the broader class of oligosaccharides demonstrates antioxidant properties, helps reduce inflammation by suppressing pro-inflammatory cytokines like IL-8, and has shown potential for anti-melanogenic and wound-healing effects. Furthermore, they can stimulate collagen synthesis, mitigate the degradation of the extracellular matrix, enhance cell proliferation, and encourage keratinocyte differentiation, collectively contributing to anti-aging outcomes.

Key findings
- 01 Galacto-oligosaccharides (GOS) at 5% (w/v) in vitro stimulated beneficial *Staphylococcus epidermidis* and inhibited pathogenic *Staphylococcus aureus* in both nutrient broth and cosmetic formulations.
- 02 Melibiose, a non-digestible oligosaccharide, demonstrated anti-inflammatory potential by suppressing IL-8 production in HaCaT keratinocytes at a 5% concentration.
- 03 A seaweed oligosaccharide–zinc complex (SOZC) significantly reduced *C. acnes* counts by 74% in vitro at 5.6%. In human trials, 5% SOZC notably improved acne vulgaris symptoms within 14 days, reducing sensitivity and promoting skin healing.
- 04 Oligochitosan displayed antimicrobial activity against *C. acnes* at 32–64 μg/mL and exhibited synergistic antibacterial effects when combined with antibiotics.
- 05 Oligosaccharides derived from *Ulva sp.* (at 1000 μg/mL) modified bacterial biofilm structures and reduced the inflammatory potential of *C. acnes* on keratinocytes by up to 39.8% in vitro.
- 06 Oligosaccharides obtained from *Medicago sativa* (alfalfa) supported collagen type I synthesis, limited extracellular matrix degradation by decreasing metalloproteinase-1 activity, and increased synthesis of cytokeratines 4 and 19 (retinoid activity markers), suggesting anti-aging properties comparable to retinol.

Stability
Specific pH stability data for Nigero oligosaccharides is currently unavailable. However, other oligosaccharides exhibit varying stability: fructo-oligosaccharides (FOS) may degrade in highly acidic conditions (pH < 4) and at elevated temperatures (>70°C), while generally remaining stable in neutral to basic environments (pH ≥ 5). Gluco-oligosaccharides and xylo-oligosaccharides typically show stability across a broader pH range, and laminaran oligosaccharide is known for its stability to heat and low pH.
Safety
Safety Profile
Specific safety assessments by the CIR or SCCS for 'Nigero oligosaccharides' have not been identified. However, the FDA has affirmed Isomalto-oligosaccharides (IMO) and certain yeast-derived glycans as Generally Recognized As Safe (GRAS) for food applications. The CIR Expert Panel has also concluded that a broad category encompassing many monosaccharides, disaccharides, and related oligosaccharides are safe for use in cosmetics, suggesting a generally favorable safety profile for the class.
