Science
Mechanism of Action
Origanum Vulgare Leaf Extract functions by providing robust antioxidant defense, neutralizing free radicals, and mitigating oxidative stress, thereby counteracting premature aging by inhibiting lipid peroxidation. Its broad-spectrum antimicrobial properties, including antibacterial, antifungal, and antiviral effects, actively combat acne-causing bacteria, prevent various skin infections, and promote a balanced skin microbiome. The extract also exerts anti-inflammatory effects, soothing irritated skin, reducing redness and swelling, and supporting the natural healing process. Furthermore, it aids in skin regeneration, reinforces the skin's natural barrier, and contributes to maintaining optimal moisture levels. It can help regulate skin oil production and offers anti-aging benefits through its potential to induce collagen synthesis and inhibit key enzymes such as collagenase, elastase, and hyaluronidase.

Key findings
- 01 Encapsulated Origanum vulgare essential oil demonstrated antibacterial activity against Staphylococcus aureus at 0.5 mg/mL (MIC) and 1 mg/mL (MBC). Ethanolic Origanum vulgare extract showed MICs against various bacteria, including 0.147 mg/mL for S. aureus and 13.9 mg/mL for S. typhimurium.
- 02 Origanum vulgare extracts showed increased antioxidant activity with concentrations ranging from 1.5625 to 800 μg/mL. Its essential oil at 10 µg/mL exhibited anti-lipid peroxidation efficacy comparable to 0.1 µg/mL of Trolox.
- 03 A highland Origanum vulgare essential oil exhibited potent anti-collagenase (92.0 ± 9.7% at 67 µg/mL), anti-elastase (53.1 ± 13.3% at 25 µg/mL), and anti-hyaluronidase (16.7 ± 0.3% at 4 µg/mL) activities.

The Formula
Formulation
Stability
Polyphenols within Origanum vulgare leaf extract demonstrate enhanced stability at a slightly acidic pH. Encapsulation techniques can significantly improve the stability of sensitive polyphenols against environmental factors such as temperature, light, pH, and moisture, facilitating sustained release, particularly at low pH (2 and 5) and low temperatures (15°C). While some forms exhibit limited water solubility, water-soluble cellular extracts are also available, and general extract solubility extends to oil and alcohol.
Conflicts
- No specific negative interactions with other cosmetic ingredients are known; however, formulators should ensure overall compatibility to maintain efficacy and safety.
- High concentrations of the extract can induce skin irritation, especially in individuals with sensitive skin.
Safety
Safety Profile
Origanum Vulgare Leaf Extract is generally considered safe for cosmetic application. However, caution is advised as highly concentrated extracts may lead to skin irritation, particularly for sensitive individuals, making patch testing recommended. While the European Union and US FDA recognize oregano extract as safe for cosmetic use, adherence to usage guidelines is important. Ethanolic extracts of Origanum vulgare L. have shown potential cytotoxic and genotoxic effects in an in vitro Allium cepa assay (onion cells) at specific concentrations. It is important to note that the essential oil, distinct from the extract, has been described as an irritant to skin and eyes and a potential sensitizer.
