Citrus Aurantifolia Fruit Extract

Citrus aurantifolia, commonly known as lime, is a citrus fruit native to Southeast Asia and now cultivated globally. The fruit extract used in skincare is derived from the lime itself and contains natural compounds including acids, vitamins, and volatile oils.In cosmetic formulations, citrus aurantifolia fruit extract functions primarily as a skin conditioning agent. It is found in approximately 0.2% of skincare products, typically in formulations where its properties are valued for texture or sensory appeal.

The extract contains natural acids and volatile compounds that interact with the skin's surface. The conditioning effect is thought to work through hydration and smoothing of the stratum corneum, the outermost skin layer.The antioxidant activity comes from naturally occurring compounds in the fruit, though the magnitude of this effect in skincare formulations remains modest compared to concentrated actives.

Citrus aurantifolia fruit extract is typically used as part of a broader formulation rather than as a standalone active. It works well in general skincare routines and can be used daily as part of cleansers, toners, or moisturisers. If using products containing lime extract, avoid direct sun exposure immediately after application to minimise any risk of photosensitivity, particularly if you have a known sensitivity to citrus fruits.

Generally well-tolerated in cosmetic formulations. However, some individuals may experience contact dermatitis or allergic reactions; those with citrus fruit allergies should patch test first. Direct exposure to fresh lime juice in sunlight can cause phototoxicity, though this risk is negligible in diluted cosmetic products.
