Science
Mechanism of Action
Primarily a film-forming humectant, its high molecular weight Konjac Glucomannan (KGM) creates a breathable barrier to bind water and prevent Transepidermal Water Loss. It also supports the lipid barrier with glycosylceramides and promotes a balanced skin microbiome.

Key findings
- 01 Oral supplementation (100mg/day, 5% glycosylceramides) significantly reduced skin dryness, hyperpigmentation, redness, itching, and oiliness in a 6-week trial with 51 volunteers (Sudeep et al., 2020).
- 02 Topical application of 0.5%-1.0% Konjac Glucomannan forms a non-occlusive film that effectively reduces Transepidermal Water Loss and maintains skin hydration.

Dusting Analysis
This ingredient is valued for its hydrating, film-forming, and thickening properties, making it an active component rather than a filler.
The Formula
Formulation
Stability
Highly stable in aqueous solutions, with viscosity stable across a wide pH range. Viscosity can increase significantly when heated or in the presence of mild alkalis, and it is vulnerable to enzymatic degradation by beta-mannanase.
Conflicts
- High concentrations of alcohol
- Strong oxidizing agents
- Certain enzymes (e.g., cellulase, mannanase)
Safety
Safety Profile
While not specifically reviewed by the CIR, it is widely used in food (GRAS) and recognized as a non-toxic, non-sensitizing vegetal extract. Dermal safety is generally high with an EWG rating of 1.
