What it is
Phlomis Koraiensis Root Extract is a botanical ingredient derived from the root of a perennial herb in the mint family, native to East Asia. It contains various compounds like flavonoids and phenolic acids that are thought to have antioxidant and anti-inflammatory activity.
How it works
In a cosmetic product, Phlomis root extract works primarily by providing antioxidant compounds that can neutralize free radicals (unstable molecules that can damage skin cells). It may also help reduce the appearance of redness by calming inflammatory pathways in the skin, though the exact mechanisms are not fully understood in human skin.
Pros
Gentle on skin
Phlomis root extract has a low irritation and comedogenic risk, making it suitable for most skin types, including sensitive and acne-prone skin.
Antioxidant support
The extract contains natural antioxidants that may help protect skin from daily environmental damage like pollution and UV exposure.
Cons and cautions
Limited human evidence
Most research on Phlomis koraiensis is lab-based or animal-based; there are few well-controlled human studies confirming its benefits in skincare.
Low concentration in products
Because it's often used at low levels (under 2%), its effects may be subtle and not noticeable on their own without other active ingredients.
Best for
- People with sensitive or easily irritated skin looking for gentle soothing ingredients
- Those interested in natural, plant-based skincare with antioxidant support
Use caution if
- Individuals with known allergies to plants in the mint family (Lamiaceae) should patch-test first
