Nephelium Lappaceum Seed Extract

Nephelium lappaceum seed extract is derived from the seeds of the rambutan fruit, a tropical plant native to Southeast Asia. The extract is obtained through solvent extraction methods and contains a notable concentration of flavonoids and phenolic compounds, which are plant molecules with antioxidant properties.In skincare formulations, this ingredient functions as a skin conditioning agent. Its primary role is to help maintain skin's appearance through its antioxidant composition, which may help protect against oxidative stress.

The extract works primarily through its concentration of flavonoids and phenolic acids. These compounds have the ability to scavenge free radicals—unstable molecules that can damage skin cells and accelerate visible ageing. By neutralising these free radicals, the extract may help protect skin from oxidative stress.Additionally, the seed extract may support skin's natural barrier function and help reduce inflammatory pathways, though the precise mechanisms in living skin require further investigation.

This ingredient is typically found in serums, moisturisers, and treatment products. As with any new skincare ingredient, introduce it gradually into your routine to monitor your skin's response. It works well alongside other antioxidants and conditioning agents, though there are no known interactions that would prevent combination use.

Generally well-tolerated in cosmetic formulations. Those with known allergies to rambutan fruit should exercise caution, though sensitisation from the extract is uncommon.
