LACTOPEROXIDASE

Description

Lactoperoxidase is a naturally occurring enzyme found in various bodily secretions, including milk, saliva, and tears. This powerful protein plays a crucial role in the body's innate defense system against harmful microorganisms. In skincare formulations, lactoperoxidase is valued for its antimicrobial and antioxidant properties, making it an effective ingredient for maintaining skin health and combating various dermatological issues.

The enzyme works by catalyzing the oxidation of thiocyanate ions, producing hypothiocyanite, a potent antimicrobial agent. This mechanism helps to neutralize bacteria, fungi, and viruses on the skin's surface, potentially reducing the risk of infections and acne breakouts. Additionally, lactoperoxidase exhibits anti-inflammatory properties, which can help soothe irritated skin and alleviate redness associated with certain skin conditions.

In skincare products, lactoperoxidase is often combined with other components of its natural enzymatic system, such as glucose oxidase and glucose, to enhance its efficacy. This ingredient is particularly beneficial in formulations designed for sensitive or acne-prone skin, as it provides gentle yet effective antimicrobial action without disrupting the skin's natural microbiome balance. Its stability and compatibility with various cosmetic ingredients make lactoperoxidase a versatile component in skincare formulations.
