Ingredient review
Perilla Leaf Water
INCI: PERILLA OCYMOIDES LEAF WATER
Perilla leaf water is a gentle, antioxidant-rich hydrosol that can help soothe and protect the skin, though research on its topical benefits is still emerging.
In plain English
Perilla leaf water is the watery byproduct created when perilla leaves are steamed to extract their oils. It contains trace amounts of the plant's beneficial compounds, like antioxidants and anti-inflammatory substances, but in a much milder form than the concentrated oil. Think of it as a very light, fragrant tea made from the leaves. In skincare, it's used as a soothing, hydrating base that can help calm irritated skin and provide a gentle layer of antioxidant protection against environmental stressors.

What it is
Perilla leaf water is a hydrosol, also known as a floral water or distillate. It is produced by steam-distilling the leaves of Perilla ocymoides (also known as Perilla frutescens), a plant in the mint family. The steam captures volatile compounds from the leaves, and when it condenses, the water-soluble components separate from the oil, leaving a fragrant, water-based liquid.
How it works
In a cosmetic product, perilla leaf water acts primarily as a soothing and antioxidant ingredient. The trace amounts of phenolic compounds (like rosmarinic acid and luteolin) it contains can help neutralize free radicals, which are unstable molecules that can damage skin cells and accelerate aging. Its anti-inflammatory properties may help calm redness and irritation. Because it is mostly water, it also provides a light, refreshing hydration without feeling heavy or sticky.
Pros
Gentle and soothing
Perilla leaf water is very mild and can help calm redness and irritation, making it suitable for sensitive skin types.
Lightweight hydration
It provides a refreshing layer of hydration without any greasy or sticky residue, ideal for layering under other products.
Cons and cautions
Low active concentration
As a hydrosol, the concentration of beneficial compounds like antioxidants is much lower than in a concentrated extract or oil, so its effects may be subtle.
Limited research
While perilla leaf has been studied for its anti-inflammatory properties, specific research on the topical benefits of perilla leaf water for skin is still limited.
Best for
- People with sensitive or easily irritated skin looking for a gentle soothing toner
- Those seeking antioxidant protection in a lightweight, water-based form
Use caution if
- Individuals with a known allergy to plants in the mint family (Lamiaceae)
- Those who prefer fragrance-free products, as perilla leaf water has a natural herbal scent
Usage tips
Safety summary
Perilla leaf water is considered very safe for topical use. It has a low risk of irritation and is generally well-tolerated, even by sensitive skin. As with any plant-derived ingredient, there is a small risk of allergic reaction in individuals sensitive to the mint family.
Research notes
Research on perilla leaf itself shows anti-inflammatory and antioxidant properties, but specific studies on perilla leaf water in skincare are limited. Most evidence is anecdotal or based on the known properties of the plant's compounds.
Common label clues
- Typical concentration
- Typically used as a base or at 10-100% in water-based formulas
