Houttuynia Cordata Extract is a popular natural extract in skincare thanks to its ability to reduce acne, soothe sensitive skin, and control excess oil. In the article below, Nguyen Ba Chemical will provide a detailed analysis of its mechanism of action, usage methods, suitable concentations, and practical precautions when using Houttuynia Cordata Extract in cosmetic formulations.

What is Houttuynia Cordata Extract?

Houttuynia Cordata Extract is a plant-derived ingredient extracted from the Houttuynia Cordata plant (family Saururaceae) using appropriate extraction methods to preserve beneficial bioactive compounds. In the cosmetics industry, this extract is registered under the INCI name Houttuynia Cordata Extract, the internationally standardized name listed in product ingredient labels.

This ingredient is typically extracted from the leaves and aerial parts of the plant, where key active compounds such as flavonoids, alkaloids, and essential oils are concentrated. The quality of the extract depends on the raw material source, cultivation conditions, and harvest time, all of which directly affect the active compound content and stability within cosmetic formulations.

Key active compounds in Houttuynia Cordata Extract

Houttuynia Cordata Extract contains various bioactive compounds that help provide antibacterial, anti-inflammatory, and soothing effects on the skin:

• Flavonoids – anti-inflammatory and antioxidant: Flavonoids help neutralize free radicals, prevent premature aging, and reduce inflammation, making them especially effective for acne-prone and sensitive skin.
• Alkaloids – mild antibacterial action: Alkaloids help control acne-causing bacteria and reduce pore clogging without drying out the skin.
• Natural essential oils – skin soothing: The essential oils in Houttuynia cordata support antibacterial activity and skin soothing, while being carefully controlled to ensure suitability for sensitive skin.

Benefits of Houttuynia Cordata Extract in skincare

Acne support and antibacterial effects for oily and acne - prone skin

Houttuynia cordata extract is highly valued in products designed for oily and acne-prone skin due to its antibacterial and anti-inflammatory properties. The natural active compounds in Houttuynia cordata help inhibit the growth of acne-causing bacteria while soothing inflamed breakouts.

Unlike strong acne-treatment actives, Houttuynia cordata extract is often used as a foundational ingredient that helps stabilize the skin and improve its overall health with long-term use.

Soothing the skin, reducing irritation and redness

Thanks to its natural anti-inflammatory properties, Houttuynia cordata extract helps quickly soothe signs of irritation such as redness, burning sensations, or tightness. This is why it is commonly found in skin-repair products, post-treatment care products, and formulations designed for sensitive skin.

Supporting oil control and pore refinement 

Houttuynia cordata extract helps regulate sebum production, reduce surface oiliness, and keep pores clear. When excess oil is controlled, the risk of acne formation is reduced, especially when combined with other skin-balancing ingredients.

Protecting the skin from oxidative stress

With its antioxidant properties and ability to inhibit cellular aging processes, Houttuynia cordata extract helps protect the skin from oxidative stress and free radical damage. As a result, it supports healthier, brighter skin and helps slow down premature aging.

Common usage levels in formulations

The typical usage level of Houttuynia cordata extract in cosmetic formulations ranges from 0.5–5%, depending on the type of extract, active compound concentration, and product objectives. For products designed for sensitive skin, lower concentrations are usually recommended to ensure safety and skin tolerance.
