Symplocos Bark Extract
INCI: SYMPLOCOS RACEMOSA BARK EXTRACT
Symplocos Bark Extract is a gentle botanical with traditional soothing and astringent benefits, but modern research is still limited.
In plain English
Symplocos Bark Extract comes from the bark of a tree native to Asia. In skincare, it's used to help calm the skin and tighten pores slightly, thanks to natural compounds called tannins. Think of it like a mild, plant-based toner ingredient that may also offer antioxidant protection. It's not a powerhouse ingredient on its own, but it can be a nice addition to soothing or balancing formulas.

What it is
Symplocos Bark Extract is a plant extract obtained from the bark of Symplocos racemosa, a tree also known as sapphire berry. The bark contains tannins, flavonoids, and other polyphenolic compounds that give it astringent and antioxidant properties.
How it works
The tannins in Symplocos Bark Extract can bind to proteins in the skin's surface, creating a mild tightening effect that may temporarily reduce the appearance of pores. Its antioxidant compounds help neutralize free radicals from environmental stressors, potentially supporting the skin's natural defense. The extract is also thought to have soothing properties, though the exact mechanism is not fully understood.
Pros
Gentle astringent action
Unlike harsh alcohol-based astringents, Symplocos Bark Extract provides a mild tightening effect that can help refine pores without stripping the skin's natural moisture.
Antioxidant support
The flavonoids in the extract help neutralize free radicals, which may reduce oxidative stress and support a more even skin tone over time.
Cons and cautions
Limited research
Most evidence for its benefits comes from traditional use and lab studies, not large-scale human trials, so its effectiveness is not as well-documented as some other botanicals.
Potential for irritation
The tannin content can be drying or irritating for very sensitive or reactive skin, especially if used in high concentrations or without proper formulation.
Best for
- People with oily or combination skin looking for a gentle astringent
- Those interested in traditional Ayurvedic skincare ingredients
Use caution if
- Individuals with very dry or compromised skin barriers, as astringents may cause further dryness
