Hydrolyzed Egg Yolk

Hydrolyzed egg yolk is a processed form of egg yolk where proteins have been broken down into smaller molecules through hydrolysis. This process makes the nutrients more stable and suitable for use in cosmetic formulations. Egg yolk naturally contains proteins, lipids, and lecithin — components that have been used in skincare and haircare for generations.In skincare and haircare products, hydrolyzed egg yolk functions primarily as a conditioning and emollient agent. It works to soften and smooth the skin's surface and hair strands, helping to improve texture and reduce moisture loss.

Hydrolyzed egg yolk contains amino acids and fatty acids that deposit onto the skin and hair surface, forming a light conditioning layer. This layer helps to seal in moisture and smooth the outer cuticle layer, creating a softer feel and reducing visible dryness.The proteins in the hydrolysate may also interact with the skin's natural proteins, potentially supporting the structure and resilience of both the stratum corneum (outer skin layer) and hair fibres, though the extent of this benefit in topical application remains limited in human studies.

Hydrolyzed egg yolk is typically found in moisturisers, conditioners, and treatment serums. There is no standard usage limit; follow the product instructions. It works well in combination with other humectants and emollients, and can be used daily as part of a regular skincare or haircare routine. Those with egg allergies should check ingredient lists, although topical use carries lower risk than ingestion.

Hydrolyzed egg yolk is generally well-tolerated and considered safe for most skin types. Those with known egg allergies should exercise caution, although the hydrolysis process may reduce allergenicity.
