Ingredient review
Linderanolide B / Subamolide A
INCI: Linderanolide B / Subamolide A
A rare plant compound with promising antioxidant and anti-inflammatory properties, but currently lacks broad human safety and efficacy data.
In plain English
Linderanolide B and Subamolide A are natural compounds found in certain plants, like the Lindera species. In skincare, they are thought to help calm redness and protect skin from environmental damage by neutralizing free radicals. However, most of what we know comes from lab studies, not large human trials, so their real-world benefits are still being explored.

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
A pair of sesquiterpene lactones—a type of natural chemical—extracted from plants in the Lindera genus, traditionally used in herbal medicine.
How it works
These compounds are believed to reduce oxidative stress by scavenging free radicals and may also inhibit certain inflammatory pathways in skin cells, potentially calming irritation.
Pros
Promising antioxidant activity
Lab studies suggest it can neutralize free radicals, which may help protect skin from premature aging caused by pollution and UV exposure.
Potential anti-inflammatory effects
Early research indicates it may calm skin inflammation, making it a candidate for soothing redness and irritation.
Cons and cautions
Lack of human studies
Most evidence comes from test-tube or animal research, so it's unclear how well these benefits translate to real-world skincare use.
Very niche availability
This ingredient is rare in commercial skincare, so finding products that contain it may be difficult.
Best for
- People with sensitive or reactive skin looking for gentle antioxidant support
- Those interested in novel, plant-based skincare ingredients
Use caution if
- Anyone with known allergies to plants in the Lauraceae family (e.g., avocado, cinnamon)
- Those who prefer ingredients with extensive human safety data
Usage tips
Safety summary
Based on limited data, Linderanolide B / Subamolide A appears safe for topical use at low concentrations. However, the lack of comprehensive human safety studies means caution is warranted, especially for those with plant allergies.
Research notes
Current evidence is limited to in vitro and animal studies showing antioxidant and anti-inflammatory activity. No large-scale human trials have been published, so efficacy claims remain preliminary.
Common label clues
- Typical concentration
- Typically used at very low concentrations (under 1%) due to potency and limited solubility
- Regulatory status
- Not specifically regulated as a cosmetic ingredient; generally considered safe for topical use at low concentrations, but no formal safety review by bodies like the CIR exists.
- Common uses
- Anti-aging serums, Soothing treatments
- Environmental note
- Sourced from wild or cultivated Lindera plants; sustainable harvesting practices are important to protect natural populations.
Good to know
- This ingredient is often listed as part of a plant extract blend, so check the full INCI list for other active compounds.
- Because it's a sesquiterpene lactone, it may have a distinct herbal scent in some formulations.
