Cucumber Peel Brown Liquid Extract — Cucumis sativus — Cosmetic Grade
Cucumber (Cucumis sativus) is one of the most beloved and widely recognized botanicals in skincare, with a long history of use for its cooling, soothing, and hydrating properties. The peel, in particular, is rich in bioactive compounds — including flavonoids, tannins, caffeic acid, and cucurbitacins — that deliver potent antioxidant, anti-inflammatory, and skin-brightening activity.
This brown liquid extract derived from cucumber peel delivers these key bioactive compounds in a ready-to-use, water-soluble form for direct incorporation into the water phase of serums, toners, eye creams, sheet masks, and soothing formulations.
Professional cosmetic ingredient — not a finished product.
Key Benefits
-
Soothing & cooling — traditionally and clinically recognized for its calming effect on irritated, inflamed, and sun-exposed skin; ideal for after-sun and sensitive skin formulations
-
Antioxidant protection — flavonoids and caffeic acid neutralize free radicals and reduce oxidative stress-driven skin aging
-
Anti-inflammatory — cucurbitacins and tannins inhibit pro-inflammatory mediators; reduces redness and puffiness, particularly around the eye area
-
Hydration support — supports skin moisture retention; complements humectant actives in hydrating serums and moisturizers
-
Brightening & tone-evening — caffeic acid contributes to tyrosinase inhibition; supports a more even, radiant complexion
-
Eye area support — anti-inflammatory and de-puffing properties make it particularly suitable for eye contour and under-eye formulations
How to Use
-
Incorporation: Add directly to the water phase or at cool-down (below 40°C) to preserve heat-sensitive flavonoids and caffeic acid
-
Recommended Usage Rate: 1–10% in finished formulations (2–5% most common for serums and toners)
-
Solubility: Water-soluble; incorporate in the water phase
-
Processing temperature: Add at cool-down (below 40°C) preferred; avoid prolonged high heat
-
pH & shelf life: Refer to your supplier's Certificate of Analysis (CoA) or Technical Data Sheet (TDS) for confirmed values
