Ingredient review
Horsetail Leaf Powder
INCI: EQUISETUM ARVENSE LEAF POWDER
A gentle, mineral-rich botanical powder that can help soothe skin and absorb excess oil, but its benefits are modest and best suited for combination or oily skin types.
In plain English
Horsetail leaf powder is simply the dried and ground leaves of the horsetail plant, a weed that grows in wet areas. In skincare, it's used mainly in face masks and powders because it can help calm irritation and soak up extra oil. It also contains natural silica, which may give skin a soft, smooth feel, but it's not a powerful active ingredient.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A finely ground powder made from the dried leaves of Equisetum arvense, commonly known as horsetail or field horsetail. The plant is rich in silica, flavonoids, and other minerals.
How it works
When mixed with water or other liquids, the powder forms a paste that can be applied to the skin. Its fine particles help absorb excess sebum and provide a gentle physical exfoliation. The flavonoids may offer mild antioxidant and soothing effects, but these are not strong enough to replace dedicated treatments.
Pros
Gentle oil control
The fine powder can help absorb excess sebum without stripping the skin, making it a good option for those with oily or combination skin who want a natural mattifying effect.
Soothing potential
Flavonoids in horsetail may provide mild anti-inflammatory benefits, which can help calm redness or irritation when used in a mask or wash-off product.
Cons and cautions
Modest evidence
Most benefits are based on traditional use and limited studies; there is no strong clinical data proving horsetail leaf powder significantly improves skin health.
Potential dryness
Because it absorbs oil, overuse or high concentrations can leave the skin feeling tight or dry, especially for those with already dry or sensitive skin.
Best for
- People with oily or combination skin looking for a gentle oil-absorbing mask
- Those who prefer natural, plant-based ingredients in their routine
Use caution if
- Individuals with very dry or dehydrated skin, as it may worsen dryness
- Anyone with a known allergy to horsetail or related plants
Usage tips
Safety summary
Horsetail leaf powder is generally safe for topical use in cosmetics. It has low irritation and comedogenic potential. However, internal use of horsetail is not recommended due to potential toxicity; stick to external skincare products.
Research notes
Research on horsetail in skincare is limited. Some in vitro studies suggest antioxidant and anti-inflammatory activity, but human clinical trials are scarce. Its primary role in cosmetics is as a gentle absorbent and soothing agent.
