What it is
This ingredient is the fruit water of Citrus depressa, the shikuwasa (also called hirami lemon), a small tart citrus traditional to Okinawa and Taiwan. It provides a light, refreshing water phase carrying water-soluble fruit components and is used to support a conditioned skin feel. It typically appears as part of the aqueous base of a formula.
Safety & warnings
Citrus fruit waters are dilute and generally gentle, but as citrus materials they may carry trace natural fragrance components such as limonene, so fragrance-sensitive individuals should take normal care. Using daytime sun protection alongside citrus-containing products is sensible.
Origin & sourcing
