Swiftlet Nest Extract

Swiftlet nest extract comes from the solidified saliva of swiftlets, small birds native to the Indo-Pacific region. This ingredient has been used in traditional foods for centuries and is composed of over 60% protein, much of which is glycosylated (bound to sugars), creating complex structures that remain largely intact during digestion.In skincare, swiftlet nest extract functions as a skin conditioning agent. When processed into peptides—smaller protein fragments—it may help support skin hydration and reduce inflammatory responses, though human clinical evidence remains limited.

Swiftlet nest extract contains bioactive peptides that are released through enzymatic processing. These peptides are small enough to potentially interact with skin cells, where they may help improve moisture retention and modulate inflammatory pathways.The glycosylated proteins in the extract may also form a protective film on the skin surface, contributing to its humectant and emollient properties. However, the exact mechanisms by which these compounds work in topical skincare remain incompletely understood.

Swiftlet nest extract is typically found in serums, essences and moisturisers at lower concentrations. As with any new ingredient, introduce it gradually and monitor your skin's response. It pairs well with other hydrating and soothing ingredients such as glycerin and niacinamide.

Swiftlet nest extract is generally considered safe for topical use and well-tolerated. Those with shellfish or seafood allergies should exercise caution, as cross-reactivity is theoretically possible with animal-derived ingredients.
