Ingredient review
Citrus Depressa Flower Water
INCI: CITRUS DEPRESSA FLOWER WATER
A gentle, aromatic floral water that offers mild toning and refreshing benefits, but lacks strong scientific backing for major skin improvements.
In plain English
This is a scented water made by steaming the flowers of the Citrus Depressa plant (a type of citrus from Okinawa, Japan). It's similar to rose water or orange blossom water. When you spray it on your skin, it feels cool and lightly tightens pores for a short time, but it doesn't have strong active ingredients to change your skin long-term. Its main job is to add a pleasant, natural citrus scent and a touch of hydration.

What it is
Citrus Depressa Flower Water is the aqueous distillate obtained from the steam distillation of the flowers of Citrus Depressa, a citrus fruit native to Okinawa, Japan. It is a byproduct of essential oil production and contains trace amounts of volatile aromatic compounds and water-soluble plant constituents.
How it works
In a cosmetic product, this flower water acts primarily as a fragrant and refreshing base. The trace natural acids and antioxidants from the flower may provide very mild astringent effects, temporarily tightening the skin's surface and giving a toned feel. It also delivers a light layer of moisture and a pleasant scent, enhancing the sensory experience of the product.
Pros
Gentle and refreshing
Provides a light, cooling mist that feels soothing on the skin without the sting of alcohol-based toners, making it suitable for daily use.
Natural fragrance alternative
Offers a subtle, pleasant citrus scent derived from the plant itself, which can replace synthetic fragrances in formulations for a more natural product experience.
Cons and cautions
Limited proven efficacy
There is very little scientific research specifically on Citrus Depressa flower water, so its skin benefits beyond mild hydration and fragrance are not well-established.
Potential for sensitivity
Even though it is generally mild, the natural aromatic compounds can still cause irritation or allergic reactions in people with very sensitive skin or citrus allergies.
Best for
- People who enjoy natural, lightly scented skincare products
- Those looking for a gentle, alcohol-free toner or facial mist
Use caution if
- Individuals with known allergies or sensitivities to citrus plants or floral waters
- Anyone seeking strong, clinically proven active ingredients for specific skin concerns
Usage tips
Safety summary
Citrus Depressa Flower Water is considered safe for topical cosmetic use with a low risk of irritation for most people. As with any plant-derived ingredient, individuals with known citrus allergies should patch test before use. It does not contain the phototoxic compounds found in some citrus essential oils (like bergamot), so it is not known to cause sun sensitivity.
Research notes
Research on Citrus Depressa flower water specifically is very limited. Most available studies focus on the fruit's peel and pulp, which are rich in antioxidants like flavonoids and vitamin C. The flower water likely contains trace amounts of these compounds, but at concentrations too low to provide significant antioxidant benefits. Its primary role in skincare is as a gentle, aromatic water.
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 US and EU when used as a fragrance ingredient or skin conditioner. No specific restrictions beyond standard cosmetic safety requirements.
- Common uses
- Toners, Mists, Facial Sprays
- Environmental note
- Sourced from the distillation of Citrus Depressa flowers, which are a byproduct of the fruit industry in Okinawa. Sustainable farming practices can minimize environmental impact.
Good to know
- Citrus Depressa is also known as Shiikuwasa, a small, green citrus fruit from Okinawa, Japan, prized for its high antioxidant content.
- Flower waters like this are often called hydrosols or floral waters and are a natural byproduct of essential oil distillation.
