Bergenia Crassifolia Root Extract

Product Description

Our Bergenia Crassifolia Root Extract is high-purity botanical material from direct factory supply, extracted from authenticated Bergenia crassifolia L. roots with batch COA traceability for hydrating and tone-evening formulators.

Arbutin, bergenin, and tannin-rich phenolics modulate tyrosinase activity, scavenge ROS, and retain cutaneous moisture as a CosIng-listed humectant in aqueous mask and serum systems.

Siberian-sourced bergenia root meets demand for arbutin-dense botanical alternatives, offering dual-marker depth beyond isolated synthetic brightening actives or generic Saxifragaceae leaf powders.

Key Benefits & Applications

Bergenia Crassifolia Root Extract delivers arbutin-bergenin actives for formulators building hydrating, tone-evening, and antioxidant skincare lines.

• Root arbutin modulates tyrosinase activity for tone-correcting water-based serums and brightening essences.
• Bergenin and phenolic antioxidants scavenge ROS and limit oxidative stress in daily protective day care.
• CosIng humectant profile retains moisture and improves skin feel in hydrogel masks and cream bases.
• Phenolic tannins calm inflammatory triggers in sensitive-skin recovery and post-blemish formulas.
• Supports even skin tone appearance in sheet-mask serums and under-eye treatment gels at 0.5–2%.

Formulation Guidelines

Use at 0.5–2% w/w in water-based hydrating and brightening systems; maintain pH 4.5–6.5 and add below 40°C to preserve arbutin markers.

• Recommended use level: 0.5–2% in essences, hydrogel masks, and brightening creams.
• Optimal formula pH: 4.5–6.5 to stabilize arbutin and bergenin actives.
• Add during cool-down below 40°C after emulsification to limit heat degradation.
• Compatible with hyaluronic acid and niacinamide in aqueous humectant bases.
• Avoid extreme alkaline pH above 7.5, which may hydrolyze arbutin content.
• Synergy: Boost tone recovery by adding Tranexamic Acid to bergenin-arbutin root in post-inflammatory spot gels.
