Citruskin is an upcycled, clear yellow, Mandarin aqueous extract that is said to help the skin defend itself from extrinsic factors and soothe sensitive skin.


Extracted from an organic mandarin co-product, Biolie’s Citruskin (INCI: Water (Aqua) (and) Propanediol (and) Citrus Reticulata Fruit Extract) offers a natural solution to soothe redness and irritation in sensitive and sensitized skin.

In this upcycling concept, Citruskin is obtained through Biolie’s enzymatic extraction process, a solvent-free, eco-process that is COSMOS compliant, according to ISO 16128. In addition to being COSMOS-certified, Citruskin is 80% organic PPAI and 100% natural in origin.

To test the active's protective benefits, researchers examined its effects in skin's innate defenses, including interleukins IL-6 and IL-8. Used at 1%, the active inhibited IL-8 production by up to 93% to decrease skin inflammation.

To assess the active's efficacy against skin redness, the company conducted an in vivo study of 30 women aged 18-60, wherein each was subjected to stripping on the forearm to induce redness. The active was then applied at 2% in a cream or placebo each day for three days to soothe the skin. After 24 hr, the active reduced skin redness by 65% compared with the placebo.
