What it is
A natural extract derived from the galls of the Rhus chinensis plant, rich in tannins and polyphenols.
How it works
The tannins in the extract bind to proteins on the skin's surface, creating a temporary tightening effect that can make pores appear smaller. Meanwhile, the polyphenols neutralize free radicals, helping to prevent oxidative stress that leads to premature aging.
Pros
Natural astringent
Helps tighten pores and control oil without harsh chemicals, making it suitable for daily use in toners or serums.
Antioxidant support
Contains polyphenols that fight free radicals, offering a layer of protection against pollution and UV stress.
Cons and cautions
Limited evidence
Most research is on the plant's traditional uses or lab studies, not on human skin, so effectiveness is not well-proven.
Potential dryness
As an astringent, it can strip natural oils if used too frequently or in high concentrations, especially for dry skin types.
Best for
- People with oily or combination skin
- Those looking for a natural antioxidant ingredient
Use caution if
- Individuals with very dry or sensitive skin
