Aspergillus … Ferment Filtrate

This ingredient is a fermented filtrate combining centella asiatica (also known as cica), a traditional Asian botanical, with swiftlet nest extract. The fermentation process breaks down plant and animal materials into smaller, more bioavailable components that can penetrate the skin more readily than their whole-ingredient counterparts.The resulting extract functions primarily as an antioxidant and skin conditioner. It works to protect skin from environmental stressors whilst supporting the skin barrier through emollient properties that help maintain hydration and suppleness.

The fermentation process breaks down the plant and animal materials into peptides, amino acids, and other small molecular compounds. These are more readily absorbed by the skin than larger molecular structures, allowing the ingredient to deliver its benefits more effectively at the cellular level.Once absorbed, the antioxidant compounds work to neutralise free radicals — unstable molecules that damage skin cells and accelerate visible signs of ageing. The emollient components sit on the skin surface and within the stratum corneum, drawing moisture in and creating a protective layer that red…

This ingredient is typically found in serums, essences, creams, and sheet masks at concentrations that support overall skincare routines rather than standalone treatment. Layer it with other hydrating or barrier-repair products to maximise its conditioning and antioxidant benefits. It integrates well into both morning and evening routines and pairs comfortably with most actives, including vitamin C, niacinamide, and gentle acids.

Generally well-tolerated across most skin types. Individuals with known sensitivity to centella asiatica or fermented ingredients should patch-test first, though allergic reactions are uncommon.
