Ingredient review
Lemongrass Flower Water
INCI: Cymbopogon Citratus Flower Water
A gentle, lightly fragrant hydrosol that can refresh and mildly tone skin, but its benefits are mostly anecdotal and it may cause sensitivity in very reactive skin.
In plain English
Lemongrass flower water is the leftover liquid from steaming lemongrass to get its essential oil. It smells like lemons and grass, and it's much gentler than the essential oil itself. In skincare, it's used as a light, watery toner or mist to give a quick refresh and a subtle tightening feel. Think of it as a very mild, scented water—not a powerhouse ingredient, but a pleasant addition to a routine.

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
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A hydrosol (also called floral water or distillate) produced during the steam distillation of lemongrass (Cymbopogon citratus) flowers. It contains trace amounts of the plant's water-soluble compounds and a very small fraction of essential oil, giving it a mild lemony scent.
How it works
When applied to the skin, lemongrass flower water provides a light, refreshing sensation. Its mild astringent properties can temporarily tighten pores and reduce excess oil on the skin's surface. The water itself also adds a thin layer of hydration, though it evaporates quickly. The fragrance can offer a sensory pick-me-up, but any active benefits are minimal compared to the essential oil.
Pros
Gentle alternative to essential oil
Lemongrass flower water contains only trace essential oil, making it far less likely to cause irritation or sensitization than pure lemongrass oil, while still offering a pleasant scent.
Refreshing sensory experience
The light, citrusy aroma can uplift your mood during application, turning a simple skincare step into a mini aromatherapy moment.
Cons and cautions
Limited proven benefits
Most of the touted benefits—like oil control or pore tightening—are based on traditional use and anecdotal reports, not robust clinical studies. You may not see dramatic changes.
Potential for fragrance sensitivity
Even though it's mild, any scented ingredient can cause redness, itching, or stinging in people with very reactive skin or fragrance allergies.
Best for
- People who enjoy light, scented toners or facial mists
- Those with normal to oily skin looking for a mild astringent boost
Use caution if
- Individuals with known citrus or grass allergies
- Those with very sensitive or compromised skin barriers who may react to any fragrance
Usage tips
Safety summary
Lemongrass flower water is considered safe for most skin types when used in cosmetic products. Its low concentration of active compounds makes it much gentler than lemongrass essential oil. However, as with any fragrant ingredient, patch testing is recommended for those with sensitive skin or known allergies to citrus or grasses.
Research notes
Scientific research on lemongrass flower water specifically is very limited. Most evidence comes from studies on lemongrass essential oil, which has demonstrated antimicrobial and anti-inflammatory properties in lab settings. The hydrosol likely retains only a fraction of these effects. A 2017 review in the Journal of Essential Oil Research noted that hydrosols generally have lower antimicrobial activity than their parent essential oils.
Common label clues
- Typical concentration
- Up to 100% in water-based products; typically 5-50% in formulations
- Regulatory status
- Generally recognized as safe for cosmetic use in the EU and US when used as a fragrance or skin-conditioning agent at typical concentrations.
- Common uses
- Toners, Mists, Facial sprays, Lightweight lotions
- Environmental note
- Lemongrass is a fast-growing, low-impact crop often cultivated without heavy pesticides, making its hydrosol a relatively sustainable byproduct of essential oil production.
Good to know
- Lemongrass flower water is often labeled as 'Cymbopogon citratus flower water' on ingredient lists.
- It is not a substitute for a moisturizer—always follow with a serum or cream if your skin needs hydration.
