What it is
Myrica Rubra Leaf/Stem Extract is a natural botanical ingredient obtained from the leaves and stems of the Myrica rubra tree, native to East Asia. It contains polyphenols, flavonoids, and tannins, which are compounds known for their antioxidant and anti-inflammatory activities.
How it works
The polyphenols in the extract donate electrons to neutralize free radicals, preventing them from causing oxidative stress that leads to premature aging. The flavonoids also help calm inflammatory pathways in the skin, reducing visible redness and sensitivity. It works best as part of a broader antioxidant strategy, not as a standalone treatment.
Pros
Gentle antioxidant
Provides free-radical protection without the irritation that some stronger antioxidants (like pure vitamin C) can cause.
Soothing potential
May help calm minor redness or sensitivity, making it suitable for reactive skin types.
Cons and cautions
Limited research
Most evidence comes from lab studies or traditional use; there are few clinical trials on human skin.
Low potency alone
As a single ingredient, it is not as powerful as established antioxidants like vitamin C or ferulic acid.
Best for
- Anyone looking for a gentle antioxidant to add to their routine
- People with normal to combination skin who want extra environmental protection
Use caution if
- Individuals with known allergies to Myrica or related plants (e.g., bayberry, wax myrtle)
