Description

Houttuynia Cordata Leaf/Stem Extract is derived from the leaves and stems of the Houttuynia cordata plant, a member of the Saururaceae family. This extract is known for its traditional therapeutic properties and is used in Asian medicine for its skin benefits. It is particularly valued in cosmetic products for its antioxidant, anti-inflammatory, and antimicrobial properties. The extract helps improve skin health by providing soothing and protective actions.

Chemical Composition and Structure:

Houttuynia Cordata Leaf/Stem Extract contains various bioactive components that confer its therapeutic properties:

Flavonoids: These compounds are crucial in protecting the skin from oxidative stress and environmental damage. The flavonoids present, such as quercetin and rutin, also offer anti-inflammatory effects, reducing skin inflammation and redness.

Saponins: The saponins present in the extract have anti-inflammatory and antioxidant properties. They can help improve skin elasticity and promote healthy, toned skin.

Phenolic Acids: These include compounds like ferulic acid and caffeic acid, known for their potent antioxidant properties. Phenolic acids help neutralize free radicals and prevent cellular damage caused by environmental exposure.

Essential Oils: The essential oils contained in the extract have antibacterial and antimicrobial properties, contributing to maintaining clean and healthy skin by reducing the risk of infections and inflammations.

Physical Properties:

Houttuynia Cordata Leaf/Stem Extract typically appears as a liquid ranging in color from light green to pale yellow. It has a fluid consistency and a natural herbal aroma that reflects its plant origin. The color and aroma may vary depending on the extraction method and the concentration of the extract.

Production Process:

Harvesting:
Leaves and stems of Houttuynia cordata are harvested during the optimal growth period to ensure the highest concentration of active principles. Harvesting must be done carefully to preserve the quality of the plant material.
Extraction:
The leaves and stems are washed and prepared for extraction. The extraction process may involve the use of plant-based solvents or water-based methods to obtain the concentrated extract. The extraction process preserves the essential bioactive components to ensure the effectiveness of the final product.

Applications:

Soothing: The extract helps calm irritated and inflamed skin, providing immediate relief from redness or sensitivity.
Hydrating: Contributes to maintaining and improving skin hydration, making it softer and smoother.
Protective: Provides a protective barrier against environmental damage and oxidative stress, helping to prevent premature aging of the skin.

Environmental and Safety Considerations:

Houttuynia Cordata Leaf/Stem Extract is generally regarded as safe for topical use. However, like all natural extracts, it should be used according to established guidelines to avoid potential allergic reactions or skin irritations. It is important to ensure that the extract is sustainably sourced and free from harmful chemicals.

INCI Functions:


Humectant. Hygroscopic compound used to minimise water loss in the skin and to prevent it from drying out by facilitating faster and greater absorption of water into the stratum corneum of the epidermis. The epidermis is the most superficial of the three layers that make up human skin (epidermis, dermis and hypodermis) and is the layer that maintains hydration in all three layers. In turn, the epidermis is composed of five layers: horny, the most superficial, granular, spinous, shiny, and basal. Humectants have the ability to retain the water they attract from the air in the stratum corneum and have the function of moisturising the skin. They are best used before emollients, which are oil-based.

Skin protectant. It creates a protective barrier on the skin to defend it from harmful substances, irritants, allergens, pathogens that can cause various inflammatory conditions. These products can also improve the natural skin barrier and in most cases more than one is needed to achieve an effective result.
