Lysozyme

Lysozyme is an antimicrobial enzyme found naturally in many biological fluids, including tears, saliva, and egg white. In skincare, it is used as a skin conditioning agent derived from these natural sources.The ingredient functions by helping to maintain skin's protective barrier and supporting its natural defence mechanisms, though its primary role in cosmetic formulations is to improve skin feel and condition rather than to deliver dramatic therapeutic effects.

Lysozyme is a naturally antimicrobial protein that works by breaking down certain cell wall components in bacteria. In skincare, this property is thought to help support skin's natural defences, though the extent of this benefit in topical application remains modest compared to other antimicrobial approaches.Beyond its antimicrobial action, lysozyme functions as a skin conditioning agent, helping to improve skin hydration and texture through its humectant and film-forming properties.

Lysozyme is typically incorporated into cleansers, serums, and moisturisers as part of a broader formulation. There are no specific usage guidelines required, as it is a gentle supporting ingredient rather than an active treatment. Use products containing lysozyme as directed by the manufacturer.

Lysozyme is generally well-tolerated and considered safe for topical use. Those with egg allergies should note that lysozyme is often derived from egg white, though the processed form used in cosmetics is unlikely to trigger reactions in most individuals. If concerned, patch test first.
