Skin Benefits

Helps reduce shine and refine the look of pores while offering antioxidant defense, though evidence for breakout-related benefits is limited. Its astringent nature can contribute to a cleaner, less greasy appearance.

Uses In Skincare & Cosmetics

Common in oil-control toners, mattifying gels, clay masks, and acne-focused spot treatments to support a fresher finish.

Comedogenic Rating

This ingredient is not typically evaluated for comedogenicity, and no standardized rating is available.

Safety

Carries an irritation risk due to high tannin content; it can cause stinging or tightness and may worsen dryness, so avoid overuse and patch test first. Not known for specific cosmetic regulatory restrictions.

Is Rhus Semialata Gall Extract a Good Ingredient?

Fair, because its tannin-driven astringency does reduce shine, but evidence for acne-related outcomes is limited and the benefit may be short-lived. It also carries a real risk of dryness and irritation, especially at higher strengths or with frequent use, which holds the rating back.
