Purslane Extract：Uses, benefits, and skincare science
Purslane extract is derived from the leaves and stems of Portulaca oleracea, a succulent herb recognized for its high content of omega-3 fatty acids, antioxidants, and anti-inflammatory compounds. Widely used in skincare and supplements, it has gained attention for its ability to support skin repair, reduce irritation, and promote general wellness.
Botanical Profile and Extraction Process
Purslane grows in various climates and is often found in gardens and wild fields. Its high resilience makes it an accessible plant source for extraction.
Extraction Method
Purslane extract is typically produced using water or alcohol-based solvents to draw out bioactive components like flavonoids, vitamins A, C, and E, glutathione, and alkaloids. These compounds are then filtered and concentrated to form liquid or powdered extracts suitable for use in cosmetics or supplements.
Key Compounds
The most studied components include alpha-linolenic acid, catecholamines, and melatonin. These play vital roles in regulating inflammation, oxidative stress, and cellular regeneration.
Applications in Skincare
Purslane extract is a common ingredient in premium skincare products due to its calming, antioxidant-rich properties.
Skin Barrier Support
By promoting hydration and enhancing skin barrier function, purslane extract helps reduce water loss and boosts skin resilience. It is especially useful in formulations targeting sensitive or inflamed skin.
Anti-Aging and Brightening
Its antioxidant profile helps neutralize free radicals, thereby reducing visible signs of aging like fine lines and dullness. It may also help lighten hyperpigmentation when used consistently over time.
Internal Health Benefits
Beyond topical use, purslane extract is also valued in dietary supplements for its nutritional content.
Rich in Omega-3 Fatty Acids
Rare among leafy greens, purslane provides alpha-linolenic acid (ALA), an essential fatty acid that supports cardiovascular and cognitive health. This makes it an appealing addition to vegetarian or vegan diets.
Anti-Inflammatory and Immune Support
Its high levels of vitamin C, beta-carotene, and other antioxidants support immune function while helping to regulate inflammatory responses throughout the body.
Formulation and Usage Tips
Whether used in serums, creams, or supplements, understanding the formulation of purslane extract is key to maximizing its benefits.
Recommended Concentrations
In skincare, concentrations between 0.5% to 2% are typically used, depending on the formulation. For supplements, it’s important to follow dosage instructions from reputable manufacturers to avoid overconsumption.
Compatibility with Other Ingredients
Purslane extract pairs well with hyaluronic acid, niacinamide, and ceramides in skincare routines. In supplements, it is often combined with turmeric, vitamin D, or other antioxidants to enhance overall health effects.
Market and Sourcing Considerations
As demand grows, consumers are encouraged to verify the source and purity of purslane extract products to ensure efficacy and safety.
Organic and Sustainable Sourcing
Look for products labeled as organic or wild-harvested, as these are less likely to be contaminated with pesticides or heavy metals. Reputable suppliers often provide third-party lab results.
Global Trends and Research
Research on purslane continues to expand, particularly in dermatology and nutrition. Many studies now explore its potential in managing skin disorders, blood sugar levels, and oxidative stress conditions. The ingredient is expected to gain more prominence in wellness and cosmetic industries in the coming years.
