Matrine
INCI: MATRINE
Matrine is a plant-derived alkaloid that helps calm redness and irritation, making it a gentle option for sensitive or acne-prone skin.
In plain English
Matrine is a natural compound found in the roots of a plant called Sophora flavescens (also known as Ku Shen). In skincare, it works like a calming signal for your skin, helping to reduce redness, swelling, and irritation.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.

What it is
Matrine is a naturally occurring alkaloid extracted from the roots of Sophora flavescens, a plant used in traditional Chinese medicine. It is a white crystalline powder that is water-soluble and known for its anti-inflammatory and antimicrobial properties.
How it works
Matrine works by inhibiting certain inflammatory pathways in the skin, such as the release of pro-inflammatory cytokines (like IL-6 and TNF-alpha). This helps reduce redness, swelling, and discomfort. It also has mild antimicrobial activity, which can help control acne-causing bacteria without disrupting the skin's natural barrier.
Pros
Calms redness effectively
Matrine targets inflammation at the cellular level, helping to visibly reduce redness and irritation after consistent use.
Gentle on sensitive skin
Unlike some harsh acne treatments, matrine soothes without drying or stripping the skin, making it suitable for daily use.
Cons and cautions
Limited research depth
While promising, most studies on matrine are small or lab-based, so its long-term benefits and safety in cosmetics are not fully established.
Potential for mild irritation
A small number of users report a slight tingling or stinging sensation, especially if they have very sensitive skin or use high concentrations.
Best for
- People with sensitive or reactive skin
- Those dealing with redness or mild rosacea
- Individuals with acne-prone skin looking for a gentle calming ingredient
Use caution if
- Those with known allergies to Sophora flavescens or related plants
- Pregnant or nursing individuals should consult a doctor due to limited safety data
Usage tips
Safety summary
Matrine is considered safe for topical cosmetic use at typical concentrations (0.1-2%). It has low irritation and comedogenic risk, but individuals with plant allergies should patch test. Pregnant or nursing individuals should consult a healthcare provider due to limited safety data.
Research notes
Research on matrine in skincare is moderate. Studies show it has anti-inflammatory and antimicrobial effects, particularly in reducing acne lesions and calming redness. However, most evidence comes from lab studies or small human trials, and more large-scale research is needed to confirm its efficacy and safety in cosmetics.
Common label clues
- Typical concentration
- 0.1% to 2%
- Regulatory status
- Matrine is not specifically regulated by the FDA as a cosmetic ingredient, but it is generally considered safe for topical use in low concentrations. It is not approved for medical treatment of skin conditions.
- Common uses
- Serums, Moisturizers, Acne treatments, Soothing masks
- Environmental note
- Sophora flavescens is a cultivated plant, so sourcing is generally sustainable. However, wild harvesting should be avoided to protect natural populations.
Good to know
- Matrine is often listed as 'Matrine' or 'Sophora flavescens root extract' on ingredient labels.
- It is not the same as marine-derived ingredients like algae or seaweed—it's a plant alkaloid.
- In traditional Chinese medicine, Sophora flavescens has been used for centuries for its anti-inflammatory properties.
