What it is
This ingredient is derived from the nest of swiftlets, which is built largely from the birds' salivary secretions and is rich in glycoproteins. Hydrolysis breaks these into smaller, more soluble fragments used in skincare to condition the skin and support a smooth, hydrated feel. Edible bird's nest is a prized ingredient in parts of East and Southeast Asia, and in sunscreens this extract functions as a supporting conditioning ingredient rather than a UV filter.
Safety & warnings
Hydrolyzed bird's nest extract is generally well tolerated at cosmetic levels. Because it is an animal-derived glycoprotein material, individuals with relevant protein sensitivities may wish to patch test. It is not associated with comedogenicity.
Origin & sourcing
Animal-derived. It is sourced from the edible nests of swiftlet birds, which are composed mainly of hardened salivary secretions, and then hydrolyzed. It is not suitable for vegan formulations.
History
Edible bird's nest has a long history of culinary and traditional use in East and Southeast Asia, and the glycoprotein-rich material has more recently been adapted as a cosmetic ingredient.
