Science
Mechanism of Action
This oil delivers a spectrum of biological activities through its abundant composition of omega fatty acids (3, 6, 7, and 9) and diverse antioxidants, including vitamins A, C, E, carotenoids, flavonoids, polyphenols, phytosterols, and squalene. It functions by protecting the skin from oxidative stress and environmental aggressors, while its anti-inflammatory properties soothe irritated and inflamed skin. Omega-7, specifically palmitoleic acid, mimics the skin's natural lipids to fortify the skin barrier. The oil actively promotes wound healing by stimulating epidermal regeneration and aiding in burn recovery, concurrently boosting collagen production, enhancing elasticity, and reducing scar visibility. It also exhibits antibacterial and antifungal effects, reduces erythema, and improves skin sensitivity. Furthermore, it offers photo-protective benefits by preventing UV-induced disturbances in redox balance and lipid metabolism and modulates inflammatory pathways by inhibiting NF-κB and STAT1 activation. It also contributes to balanced sebum production.

Key findings
- 01 In a nanoemulsion gel, demonstrated superior wound-healing, antibacterial, and antifungal activity compared to pure oil and a 0.5% concentration.
- 02 Prevented UV-induced disturbances in redox balance and lipid metabolism in human skin fibroblasts and keratinocytes, suggesting photo-protective potential.
- 03 Effectively incorporated into various skincare formulations, including vitamin fruit serums (0.3%), sunscreens for acne-prone skin (0.5%), and facial treatments for hyperpigmentation (1%).

Dusting Analysis
Reported concentrations in various products and studies range from 0.3% to 1.0%, indicating its use at levels expected to deliver therapeutic benefits rather than mere marketing claims.
The Formula
Formulation
Stability
Preserving the oil's nutritional integrity and stability in formulations is crucial. Dilution with a carrier oil is recommended, especially for facial applications. Formulating as a nanoemulsion gel has been shown to enhance permeation and mitigate common issues like product leakage or dripping.
Conflicts
- High concentrations may lead to mild comedogenicity and can temporarily stain the skin, necessitating careful formulation and dilution.
- Due to its rich fatty acid content, it may not be suitable for formulations specifically designed to be 'Malassezia folliculitis (fungal acne) safe'.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel noted 'insufficient data' for safety determination in 2011, and a re-review is currently prioritized. Despite this, Hippophae Rhamnoides Seed Oil is generally considered safe and well-tolerated across most skin types, including sensitive skin, with a low risk of allergies. However, it should be diluted before topical use, particularly for facial applications. Overly high concentrations carry a potential for mild comedogenicity and can impart a temporary stain to the skin.
