Science
Mechanism of Action
Egg Oil, also known as egg yolk oil, operates by delivering a complex blend of essential fatty acids (including Omega-3 DHA and Omega-6 arachidonic acid), cholesterol, phospholipids, and antioxidants (such as lutein and zeaxanthin) directly to the skin. These components are critical for fortifying the skin's barrier function, enhancing cell membrane integrity, and providing deep moisturization. Topically, cholesterol aids in repair and protection, while antioxidants combat oxidative stress, mitigating environmental damage and signs of aging. It fosters skin cell regeneration, accelerating healing and minimizing scar formation. Furthermore, Egg Oil forms a light, non-comedogenic protective layer that locks in moisture, exhibits anti-inflammatory and antimicrobial properties, and modulates immune responses to improve conditions like atopic dermatitis by upregulating key barrier genes. It also functions as a penetration enhancer, optimizing the delivery of other beneficial ingredients.

Key findings
- 01 Incorporated into cosmetic formulations (hand, body, and massage creams), Egg Oil demonstrates a noticeable emollient effect, promoting skin softness and smoothness.
- 02 In an in vitro study, this concentration significantly boosted the metabolic activity of skin cells, indicating enhanced cellular vitality.
- 03 Studies in mouse and cell models revealed that topical application ameliorated atopic dermatitis-like symptoms by inhibiting STAT3 signaling, increasing regulatory T cells, and improving critical skin barrier functions.
- 04 In diabetic rats, topical application was observed to reduce mast cell concentration in excisional wounds and accelerate the wound healing process.

The Formula
Formulation
Stability
Egg Oil is a lipophilic ingredient, insoluble in water but readily dissolves in most organic solvents. While no specific optimal pH range for its stability has been identified, modern industrial extraction methods typically maintain temperatures below 40°C to safeguard its thermosensitive components.
Safety
Safety Profile
Egg Oil has not been specifically reviewed by the Cosmetic Ingredient Review (CIR) or the Scientific Committee on Consumer Safety (SCCS) for cosmetic use. However, it is generally considered safe for topical applications, as purified egg oil is typically free of the egg proteins responsible for most allergic reactions to eggs. While egg yolk holds a GRAS status for food by the FDA, this does not automatically translate to cosmetic safety and would require independent evaluation.
