Organic Sea Buckthorn CO₂ Extract
INCI: Hippophae Rhamnoides Seed Oil, Rosmarinus Officinalis Leaf Extract
Origin
Sea Buckthorn CO₂ Extract is obtained from the crushed seeds of Hippophae rhamnoides, a hardy shrub known for its vivid orange berries. The certified organic extract used by AREUM is produced through supercritical carbon dioxide extraction, a process in which pressurised CO₂ behaves partly like a liquid and partly like a gas, allowing it to draw the oil-soluble compounds from the seeds. Once extraction is complete, the carbon dioxide separates cleanly from the oil.
The resulting extract is naturally concentrated and rich in essential fatty acids, particularly linoleic and alpha-linolenic acids, alongside oleic acid and naturally occurring plant antioxidants. Sea buckthorn seed oil differs from the oil obtained from the fruit pulp, which has a markedly different fatty acid composition.
How AREUM Uses It
We use Certified Organic Sea Buckthorn CO₂ Extract in Grace Facial Oil, where it works alongside bakuchiol, rosehip, camellia, jojoba, meadowfoam, olive-derived squalane and vitamin E.
Although present in a small amount, it is one of Grace’s most concentrated botanical ingredients. It brings essential fatty acids, antioxidant care and a naturally warm golden hue to the formula, complementing the nourishing and restorative qualities of the complete oil blend.
Why AREUM Chose Sea Buckthorn CO₂ Extract
We chose a seed-derived CO₂ extract rather than a conventionally pressed sea buckthorn oil for its concentration, purity and carefully preserved botanical composition.
Supercritical CO₂ extraction allows the oil to be obtained without conventional organic solvents and at relatively controlled temperatures. It is particularly suited to capturing delicate oil-soluble plant compounds while allowing the carbon dioxide to separate from the finished extract once the process is complete.
We specifically chose seed oil because it is naturally abundant in linoleic and alpha-linolenic acids, two essential fatty acids that help support the skin’s lipid barrier. Within Grace, its concentrated character allows us to include these benefits without overwhelming the formula’s silky texture or leaving the skin feeling overly rich.
Benefits for Skin
Sea Buckthorn Seed Oil acts as a replenishing emollient, helping soften the skin and support its natural protective barrier. Its linoleic and alpha-linolenic acids help maintain moisture and suppleness, making it especially valuable for skin that feels dry, delicate or less resilient.
Its naturally occurring antioxidant compounds complement the vitamin E, bakuchiol and botanical oils within Grace, helping care for skin exposed to everyday environmental stress. It contributes to skin that feels nourished, comfortable and supported, with a softer and more radiant appearance over time.
