Science
Mechanism of Action
This ingredient primarily functions as an antioxidant, actively scavenging free radicals to protect skin from oxidative stress. It exhibits anti-inflammatory effects, which can calm irritation, and possesses antimicrobial and antibacterial properties beneficial for conditions like acne and dermatitis. Additionally, it helps regulate sebum production, minimizing pore clogging, and provides humectant properties to support skin hydration and elasticity, contributing to an overall toned and healthy appearance.

Key findings
- 01 In an in-vitro study, water and ethanol extracts of juniper fruit demonstrated strong antioxidant activity, inhibiting linoleic acid peroxidation by 73% to 93% at concentrations of 20, 40, and 60 µg/mL.
- 02 Another in-vitro study using water extracts showed moderate to potent inhibitory activity against bacterial triggers of inflammatory conditions (e.g., rheumatoid arthritis, ankylosing spondylitis) and certain cancer cell lines (HeLa, CaCo2) with IC50 values between 1300-2500 µg/mL.

Stability
The pH range of juniper berry extracts varies from 4.97 to 7.15, indicating suitability within typical cosmetic pH ranges. Juniperus Communis Fruit Water is often formulated with propylene glycol and preservatives to maintain stability.
Safety
Safety Profile
The CIR Expert Panel determined insufficient data to assess the safety of Juniperus Communis Fruit Extract for cosmetic use. While large oral doses in animal studies showed effects on fertility, dermal tests on juniper oils generally showed no irritation, though juniper tar showed some sensitization. Terpinen-4-ol, a component of juniper volatile oil, is known to be an irritant. However, Juniperus Communis Fruit Water is a milder hydrosol form compared to concentrated extracts or essential oils. Juniperus communis berry oil is FDA GRAS for food consumption.
