Ingredient review
Pectolinarin
INCI: Pectolinarin
Pectolinarin is a plant-derived flavonoid with antioxidant and soothing potential, but research in cosmetics is still early.
In plain English
Pectolinarin is a natural compound found in plants like cirsium and linaria species. In skincare, it acts as an antioxidant, helping to neutralize free radicals that can damage skin cells. It may also have soothing properties, making it a gentle addition to formulations aimed at calming irritated skin. Because it's a newer ingredient in cosmetics, most evidence comes from lab studies rather than human trials.

Quick decision guide
Useful, but context matters
Pectolinarin is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Pectolinarin.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
Pectolinarin is a flavonoid glycoside, a type of plant pigment with antioxidant activity. It is extracted from plants such as Cirsium setidens (Korean thistle) and Linaria vulgaris (common toadflax).
How it works
In a cosmetic product, pectolinarin works by donating electrons to neutralize free radicals, thereby reducing oxidative stress on the skin. It may also inhibit certain inflammatory pathways, contributing to a soothing effect.
Pros
Antioxidant support
Helps protect skin from free radical damage caused by UV and pollution, which can lead to premature aging.
Gentle soothing
May reduce redness and irritation, making it suitable for sensitive skin types when formulated properly.
Cons and cautions
Limited human research
Most evidence comes from lab studies, so real-world benefits on skin are not yet well-documented in peer-reviewed human trials.
Source variability
Effectiveness can depend on the plant source and extraction method, leading to inconsistent quality across products.
Best for
- People looking for antioxidant support in their routine
- Those with sensitive or easily irritated skin seeking gentle soothing ingredients
Use caution if
- Individuals with known allergies to plants in the Asteraceae family (e.g., daisies, ragweed) should patch test first
Usage tips
Safety summary
Pectolinarin has low irritation and comedogenic risk based on its chemical structure and limited use data. However, as with any plant extract, patch testing is recommended for those with plant allergies.
Research notes
Research on pectolinarin is primarily in vitro (lab studies) showing antioxidant and anti-inflammatory activity. Human clinical studies specific to cosmetic use are lacking, so evidence is considered emerging.
Common label clues
- Typical concentration
- Typically used at 0.1% to 1% in leave-on products
- Regulatory status
- Pectolinarin is not specifically regulated by the FDA as a cosmetic ingredient; it is generally considered safe when used in low concentrations as part of a cosmetic formulation.
- Common uses
- Serums, Moisturizers, Soothing treatments
- Environmental note
- Sourced from wild or cultivated plants; sustainable harvesting practices are important to avoid overharvesting of source species.
Good to know
- Pectolinarin is often found in traditional herbal medicine preparations.
- It is not a common ingredient, so it may appear in niche or natural-focused skincare lines.
