Ingredient review
Miyamayomena Leaf/Stem Extract
INCI: MIYAMAYOMENA KORAIENSIS LEAF/STEM EXTRACT
A gentle plant extract with antioxidant potential, but research is very limited — it's not a proven powerhouse ingredient yet.
In plain English
This is an extract from a plant called Miyamayomena koraiensis, which grows in parts of Asia. In skincare, it's added to products like serums and moisturizers to provide antioxidant protection (helping defend skin from environmental stress) and to calm irritation. Because it's not widely studied, its benefits are mostly theoretical based on its plant origin, and it's considered safe but not essential.

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 water- or solvent-based extract derived from the leaves and stems of the Miyamayomena koraiensis plant, a member of the Asteraceae family. It contains natural compounds like flavonoids and phenolic acids that may offer antioxidant and anti-inflammatory activity.
How it works
The extract's antioxidant compounds can neutralize free radicals (unstable molecules that damage skin cells), potentially reducing oxidative stress. Its soothing properties may help calm redness or irritation by modulating inflammatory pathways, though the exact mechanism is not well-documented in peer-reviewed studies.
Pros
Gentle on skin
Low irritation and comedogenic risk make it suitable for sensitive skin types, including those prone to redness or breakouts.
Natural antioxidant source
Derived from a plant, it offers a nature-based way to support skin defense against daily pollution and UV stress (though not a substitute for sunscreen).
Cons and cautions
Limited research
There are almost no published human studies on this extract, so its real-world benefits are uncertain compared to well-studied antioxidants like vitamin C or niacinamide.
Potential allergen
As a member of the Asteraceae plant family, it may cause allergic reactions in individuals sensitive to related plants like ragweed or chamomile.
Best for
- Anyone looking for a gentle, plant-based antioxidant
- Those with sensitive or reactive skin who want a low-irritation option
Use caution if
- People with known allergies to Asteraceae plants (e.g., ragweed, daisies, marigolds)
Usage tips
Safety summary
Considered safe for topical use at typical cosmetic concentrations. The main risk is a potential allergic reaction in individuals sensitive to Asteraceae plants. Irritation and comedogenic risks are low.
Research notes
Evidence is limited to general knowledge of plant antioxidants and a few in vitro studies on related species. No robust clinical trials on human skin exist for this specific extract.
Common label clues
- Typical concentration
- 0.1% to 2% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in low concentrations, but not specifically approved or reviewed by the FDA or EU CosIng database as a standalone active.

- Serums, Moisturizers, Toning lotions
- Environmental note
- Sourcing is likely from wild or cultivated plants in East Asia; sustainability practices are not publicly documented for this specific extract.
Good to know
- This extract is not a common ingredient in mainstream skincare; it's more likely found in niche or K-beauty formulations.
- The plant Miyamayomena koraiensis is native to Korea and parts of China, and its traditional uses are not well documented in Western herbalism.
