Science
Mechanism of Action
This botanical water, along with various extracts from the Thuja orientalis plant, provides a range of skin benefits through its active constituents. It is abundant in antioxidants, including flavonoids like kaempferol and isoquercetin, which combat free radicals to mitigate signs of premature aging. Its anti-inflammatory properties help to reduce redness and soothe irritated skin, promoting a more balanced complexion. Furthermore, Thuja Orientalis Water possesses mild antimicrobial effects that can assist in maintaining skin flora equilibrium. In hair care, hot water extracts have been shown to stimulate hair growth by initiating the anagen phase and upregulating key proteins such as β-catenin and Sonic hedgehog within hair follicles. The ingredient also imparts moisturizing, toning, and astringent qualities to the skin.

Key findings
- 01 An ethanol extract of Thuja orientalis L. seeds demonstrated efficacy in ameliorating skin lesions in dinitrofluorobenzene-induced mice models, reducing erythema, melanin, and roughness. It also prevented epidermal hyperplasia and hyperkeratosis, alongside providing a moisturizing effect on the skin.
- 02 Water and ethanolic extracts exhibited significant antioxidant activity, inhibiting the hydrolysis of DNA by 72.859% and 65.312% respectively, suggesting protection against oxidative damage.
- 03 A hot water extract, applied at a concentration of 5.05 mg/cm²/day, promoted hair growth in telogenic C57BL/6 N mice by inducing the anagen phase and increasing both the number and size of hair follicles. It also led to earlier expression of β-catenin and Sonic hedgehog (Shh) proteins in hair follicles.

Safety Profile
While the leaves of the Thuja orientalis plant are recognized as toxic if ingested, Thuja Orientalis Water is a distillate (hydrosol), typically containing lower concentrations of potentially irritating compounds like thujone found in the plant's essential oils. However, the plant itself has been documented to cause skin allergies in sensitive individuals, indicating a moderate potential for sensitization, even in hydrosol form. Official safety assessments by regulatory bodies like CIR or SCCS specifically for 'Thuja Orientalis Water' are not currently available.
