Science
Mechanism of Action
Dendrobium candidum polysaccharides (PDC) actively support epidermal barrier function by upregulating mRNA expression of critical tight junction proteins, occludin and claudin-1. This extract boosts skin hydration by increasing levels of filaggrin (FLG), caspase-14, and bleomycin hydrolase. Additionally, it demonstrates anti-inflammatory action through the inhibition of nitric oxide release and pro-inflammatory cytokine production. Broader research on Dendrobium species also suggests potential antioxidant, anti-aging (via MMP2 inhibition), and skin brightening (via tyrosinase inhibition) properties.

Stability
This extract exhibits good stability in aqueous systems, supported by its water solubility and the common use of water extraction methods for Dendrobium candidum leaf extracts. A related Dendrobium extract was also found to be stable at 0.2% in a skincare preparation.
Safety
Safety Profile
Dendrobium candidum extract has not been specifically reviewed by regulatory bodies such as CIR, SCCS, or FDA for topical cosmetic use. While no specific human safety or sensitization data is available for this extract, a study on a related Dendrobium extract (Dendrobium kentrophyllum) indicated safety for human skin cells at concentrations ranging from 6.25–100 μg/mL.
