Science
Mechanism of Action
Extracts from Juniperus phoenicea, including its essential oils, are noted for their robust antioxidant activity, primarily attributed to their rich phenolic and flavonoid compounds. These components facilitate radical scavenging and enhance the skin's reducing power. Anti-inflammatory effects are observed through the reduction of edema and modulation of inflammatory markers, potentially involving compounds such as hexadecanoic and stearic acids. Additionally, these extracts exhibit anti-lipase activity, which may be relevant for managing sebum production. The berry essential oil of Juniperus phoenicea also demonstrates the ability to inhibit tyrosinase, an enzyme crucial for melanin synthesis, suggesting potential skin-brightening properties.

Key findings
- 01 Potent antioxidant activity (in vitro) has been observed in Juniperus phoenicea hydroethanolic extracts, with IC50 values of 12.22 μg/ml for DPPH scavenging and 15 μg/l in β-carotene bleaching assays.
- 02 Juniperus phoenicea extracts demonstrated inhibitory effects on human lipases, with an IC50 of 1.33±0.10 mg/mL for the ethyl acetate extract, identifying apigenin-7-O-glucoside as a key inhibitor.
- 03 Anti-inflammatory and analgesic effects were evident in mice, where Juniperus phoenicea hydroethanolic extract at 100 mg/kg BW reduced carrageenan-induced paw oedema.
- 04 Juniperus phoenicea berry essential oil exhibited a high capacity to inhibit melanin synthesis by suppressing both monophenolase and diphenolase activities of tyrosinase.

Stability
While specific stability information for Juniperus phoenicea gum extract is not available, essential oils derived from juniper are known to be sensitive to UV radiation and heat, necessitating storage in amber glass bottles away from direct light and high temperatures.
Conflicts
- Prohibited for use as a fragrance ingredient by IFRA due to classification as having 'High acute toxicity'.
Safety
Safety Profile
The CIR Expert Panel determined insufficient data to ascertain the safety of Juniperus phoenicea gum extract for cosmetic use, citing a lack of information on its manufacturing process, genotoxicity, dermal reproductive/developmental toxicity, and specific irritation/sensitization. IFRA has classified this ingredient with 'High acute toxicity' and prohibits its use as a fragrance. Additionally, general juniper extracts are advised to be avoided during pregnancy and may potentially cause skin allergic reactions.
