Science
Mechanism of Action
This oil functions multifacetedly, primarily through its high content of fatty acids, including linoleic, linolenic, palmitic, and oleic acids, which are crucial for forming a robust protective lipid barrier, thereby minimizing transepidermal water loss and preserving skin moisture. This action is pivotal in repairing and safeguarding the skin barrier. Beyond barrier support, it actively promotes skin cell regeneration and collagen synthesis, vital for maintaining skin structure and elasticity. Biologically active compounds such as squalene and kaempferol confer anti-inflammatory properties, aid in reducing pigmentation, and support healthy blood circulation. The oil also activates OVOL-1 expression, enhancing tight junction proteins for improved barrier integrity, and effectively suppresses pro-inflammatory factors. As a significant source of polyphenols and antioxidants, including Vitamin E, it efficiently neutralizes free radicals, mitigating oxidative damage and consequently reducing the appearance of fine lines and wrinkles. Its natural tannins contribute to lightening hyperpigmentation, fostering a more radiant and uniformly toned complexion, while its non-comedogenic and natural antibacterial qualities offer efficacy against acne-causing bacteria.

Key findings
- 01 Paeonia suffruticosa seed oil (2.5 to 50 mg/mL) demonstrated concentration-dependent scavenging of DPPH radicals, exhibiting an EC50 of 29.30 mg/mL. This indicates a more potent free radical scavenging capacity compared to extra virgin olive oil.
- 02 Moderate oral intake of Paeonia suffruticosa seed oil (e.g., 1.3, 4.0, or 12.0 g/kg/d in mice; 2.5 or 6.0 g/kg/d in rats) provided significant protection against various oxidative damages, including tetrachloromethane-induced acute liver injury in mice and diet-induced hyperlipidemia in rats, affirming its in vivo antioxidant capabilities.
Transparency
Dusting Analysis
As a rich fixed oil, Paeonia Rockii Seed Oil provides direct functional benefits as an emollient, skin conditioner, and active botanical. Its efficacy is inherent to its composition and is generally observed when incorporated as a meaningful percentage of a formulation, rather than through 'dusting' at sub-efficacious trace amounts typical of some highly concentrated actives.
The Formula
Formulation
Stability
Paeonia Rockii Seed Oil is a fixed oil recognized for its nutrient density when cold-pressed, virgin, and unrefined, owing to its high content of alpha-linolenic acid (ALA), linoleic acid, and oleic acid. To ensure optimal stability and extend shelf life, particularly against oxidation of its unsaturated fatty acids, storage in light-blocking containers such as amber glass bottles is highly recommended.
Safety
Safety Profile
The Expert Panel for Cosmetic Ingredient Safety concluded Paeonia Suffruticosa Seed Oil to be safe for cosmetic use under current practices. Given that Paeonia rockii is recognized as a cultivar of Paeonia suffruticosa, these safety assessments are considered applicable. Industry guidelines emphasize minimizing impurities such as heavy metals and pesticide residues, adhering to strict limits established by regulatory bodies like the FDA and EPA.
