Science
Mechanism of Action
This botanical extract operates on multiple fronts: its rich composition of flavonoids and saponins provides significant antioxidant defense against environmental stressors like pollution and UV radiation. These compounds also contribute to its anti-inflammatory actions, which reduce skin redness and provide a soothing effect. Furthermore, it aids in restoring the skin's natural moisture balance, diminishing dryness and tightness for a smoother texture. The extract's preservative capabilities, attributed in part to natural parahydroxy benzoic acid (PHBA), inhibit microbial growth, thereby extending product shelf life.

Key findings
- 01 Lonicera caprifolium L. flower essential oil demonstrated potent wound healing, achieving 98.08% wound closure by day 12, and exhibited significant antinociceptive (pain-reducing) activity with a 73.88% writhing reduction. (Note: This study refers to the essential oil, not the aqueous extract typically used in cosmetics for these specific effects.)
- 02 A blend containing Lonicera japonica and Lonicera caprifolium extracts (Plantservative WSr) at concentrations of 0.5%-1% was effective as a broad-spectrum antimicrobial preservative, inhibiting bacteria, yeast, and mold growth.

It is also temperature tolerant up to 95°C (208°F), allowing for flexible integration during manufacturing. It maintains emulsion stability and does not alter surfactant viscosity.
Synergies
- Lonicera Japonica (in a lonicerin complex) for enhanced preservative action and stability.

Safety
Safety Profile
Generally regarded as safe for cosmetic use, Lonicera Caprifolium Extract has a low irritancy rating. While a blend including this extract was determined to be 'non-irritating on intact human skin' at 3.5% in a 24-hour occlusive patch test, a patch test is still advisable for individuals with highly sensitive skin or known predispositions to allergies. The European Cosmetics Regulation permits its use, adhering to general usage guidelines. EWG rates it 'low' for irritation but 'Restricted' for EWG VERIFIED products without further substantiation.
