Science
Mechanism of Action
Egg powder's diverse constituents exert multiple beneficial effects on the skin. Egg whites, abundant in proteins like albumin, exhibit astringent properties that visibly minimize pore size and help regulate excess oil. They also stimulate collagen production, leading to improved skin elasticity and firmness. Bioactive peptides isolated from egg whites can inhibit tyrosinase activity, an enzyme crucial for melanin synthesis, thereby offering potential anti-pigmentation benefits, with some showing up to 70.01% melanin level reduction in cell models. The enzyme lysozyme contributes antibacterial action, potentially targeting acne-causing bacteria. Egg yolks deliver essential Omega-3 and Omega-6 fatty acids, alongside lecithin, which profoundly soften skin, maintain optimal moisture levels, and provide antioxidant and anti-inflammatory support, particularly beneficial for acne-prone complexions. Egg yolk lipids further enhance anti-inflammatory, anti-microbial, and healing processes, while promoting skin elasticity. Carotenoids such as lutein and zeaxanthin in egg yolks act as potent antioxidants, mitigating signs of aging and reversing damage from environmental stressors. The eggshell membrane, a complex matrix of collagens (Types I, V, X), glycosaminoglycans, hyaluronic acid, keratin, and elastin, is instrumental in boosting skin hydration, elasticity, stimulating cellular activity, supporting collagen synthesis, and reducing the appearance of wrinkles. Overall, the combination of 18 amino acids, vitamins (A, E, B7/biotin), and minerals (zinc, selenium) within egg proteins collectively supports skin repair, protects against free radical damage, and enhances overall skin tone and texture.

Key findings
- 01 An open-labeled 4-week study on human skin demonstrated that formulations containing a nano-sized Natural Egg Membrane Concentrate (NEMCTM) visibly reduced wrinkles, treated acne and dry skin, improved hydration, and smoothed skin, in contrast to formulations without NEMCTM.
- 02 In a cell-based model, chicken egg white-derived peptides and hydrolysates, specifically at 5 mg/mL, inhibited intracellular tyrosinase activity by up to 45.39% and melanin levels by up to 70.01%, indicating significant anti-pigmentation potential.

No specific data regarding dusting properties or inhalation risks for egg powder in cosmetic manufacturing was identified.
The Formula
Formulation
Stability
Egg proteins are highly sensitive to thermal and pH-induced denaturation, with egg white proteins exhibiting minimum solubility and potential coagulation above approximately 60°C. Extreme pH levels can also inactivate active ingredients. For formulations incorporating whole egg powder, a specialized manufacturing approach suggests adding it to the oil phase at 60-90°C to encapsulate and protect it from coagulation and denaturation. While egg white inherently possesses an alkaline pH (8.08-10.11), precision skincare products are optimally formulated between pH 4.5 and 5.5 to align with skin's natural acidity, ensure preservative efficacy, and maintain active ingredient stability. This disparity in optimal pH requires careful formulation to preserve egg powder's integrity and efficacy.
Safety
Safety Profile
The European Commission's CosIng database specifies that 'EGG POWDER' and 'DRIED EGG YOLK' are prohibited in cosmetic products under Annex II, entry 419, of Cosmetics Regulation 1223/2009, due to their classification as Category 1 and 2 animal material. While albumen (egg white) is generally considered a safe, natural ingredient, a patch test is recommended for individuals with known sensitivities or potential allergic reactions. Eggshell membrane is noted to be less allergenic compared to traditional egg components.

Verdict
Egg powder offers promising multi-functional benefits for skin health, including anti-aging and pigmentation control; however, significant regulatory prohibitions in regions such as the EU warrant a cautious approach to its inclusion in cosmetic formulations.
