Nephelium Lappaceum Peel Extract

Nephelium lappaceum peel extract is derived from the rambutan fruit, a tropical plant native to Southeast Asia. The extract is obtained from the fruit's peel and contains a concentrated profile of polyphenolic compounds, including quercetin and other flavonoids that give the ingredient its biochemical activity.In skincare formulations, this extract functions as a skin conditioner. Its primary mechanism centres on antioxidant activity and the ability to interact with enzymes involved in skin ageing processes, particularly those responsible for breaking down structural proteins.

The peel extract works primarily through its polyphenolic content, which exhibits antioxidant capacity. These compounds can scavenge free radicals (reactive oxygen species) that accumulate in skin cells and contribute to ageing.Additionally, research suggests the extract may inhibit elastase and collagenase—enzymes that break down elastin and collagen respectively. By moderating these enzyme activities, the ingredient may help preserve skin's structural integrity, though the extent of this effect in live skin remains under investigation.

Nephelium lappaceum peel extract is typically used as a supporting ingredient within broader skincare formulations rather than as a standalone product. It integrates well into serums, essences, and moisturisers designed to address signs of ageing. As with any new ingredient, introduce it gradually to allow your skin to adapt.

The extract has demonstrated safety in cellular studies with no adverse effects on human fibroblasts. It is generally well-tolerated, though patch testing is advisable if you have known sensitivities to tropical fruit extracts.
