ROE (rosemary CO₂ extract) (Rosmarinus officinalis) is a highly concentrated botanical extract widely used in skincare formulations for its powerful antioxidant protection and ability to stabilize oils and extend product shelf life. Rich in bioactive compounds such as carnosic acid and carnosol, it helps protect both the skin and the formulation from oxidative stress, promoting a more stable, effective, and high-performing skincare product.
ROE is derived from the leaves of the rosemary plant through supercritical CO₂ extraction, a method that preserves the plant's most potent antioxidant compounds without the use of high heat or harsh solvents.
Unlike rosemary essential oil, rosemary CO₂ extract is not primarily used for fragrance—it is used for its functional antioxidant properties in formulations. It is oil-soluble and highly effective even at low concentrations, making it a valuable ingredient in modern clean and natural skincare formulations.
In skincare formulations, ROE functions as both an antioxidant and formulation-stabilizing ingredient, helping to slow the oxidation of carrier oils, butters, and lipid-based products, which can otherwise degrade over time.
In addition to protecting formulations, ROE also provides skin benefits, helping to reduce the impact of free radicals, inflammation, and environmental stressors, which contribute to premature aging and skin imbalance.
ROE is typically used at very low concentrations and is considered non-comedogenic, making it suitable for most skin types when properly formulated.
Key Benefits
• Powerful Antioxidant Protection – Helps defend against free radicals and oxidative stress
• Extends Product Shelf Life – Helps prevent oxidation of oils and butters
• Supports Skin Barrier – Helps protect against environmental damage
• Anti-Inflammatory Properties – Helps calm irritation and redness
• Enhances Formulation Stability – Improves overall product performance and longevity
• Lightweight & Non-Comedogenic – Suitable for most skin types
• Highly Potent – Effective at very low usage levels
Why It Works
ROE (rosemary CO₂ extract) works due to its high concentration of carnosic acid and other antioxidant compounds, which help neutralize free radicals and prevent oxidative degradation in both the skin and the formulation.
Its antioxidant activity helps protect delicate fatty acids in oils and butters, slowing rancidity and maintaining product integrity over time. This makes it especially valuable in formulations containing polyunsaturated oils.
At the skin level, these same antioxidant compounds help reduce inflammation and environmental stress, supporting a more balanced and resilient complexion.
By combining formulation stability with skin-protective benefits, ROE plays a dual role in creating long-lasting, high-performance skincare products.
