Actinidia Chinensis Fruit Extract

Actinidia chinensis fruit extract is derived from kiwifruit and contains polysaccharides — naturally occurring carbohydrate compounds found within the fruit's tissues. In skincare formulations, these polysaccharides function as an emollient and skin conditioning agent, helping to soften the skin surface and support the skin's natural moisture barrier.

The extract also contains ascorbic acid (vitamin C) and other plant compounds, though the concentration and bioavailability of these components in cosmetic products can vary depending on extraction and processing methods.

The polysaccharides in kiwifruit appear to interact with cell receptors and energy-production pathways in skin cells (keratinocytes and fibroblasts). Research conducted in controlled laboratory settings has shown these compounds may stimulate cell proliferation and mitochondrial activity — essentially encouraging skin cells to function more actively — whilst also supporting collagen synthesis, a protein essential for skin structure and elasticity.

As an emollient, the extract also forms a protective layer on the skin surface, helping to reduce transepidermal water loss and maintain hydration. However, most evidence for these mechanisms comes from cell cultures and laboratory models rather than clinical studies on living skin.

Kiwifruit extract is typically found in serums, moisturisers, and hydrating products at concentrations ranging from 1% to 57%, though exact percentages vary by formulation. It can generally be used daily as part of your regular skincare routine. If you have sensitive skin or are introducing a new product, patch test first to ensure compatibility. The ingredient works well alongside other hydrating or nourishing ingredients and does not require any special application technique.
