There are legends that many queens and empresses took milk baths daily for a youthful appearance. Today many skincare formulations contain pasteurized milk or its components like lactic acid, lactose, or proteins, which have beneficial effects on the skin.

Milk contains many proteins (usually marked as Lactis proteinum) that have scientifically proven benefits on skin regeneration, cell renewal, and active prebiotics. Also, milk proteins improve the stability of other important ingredients, as well as be a part of the delivery system enhancing penetration of active substances into the deeper layers of the skin.

Milk proteins are complete proteins and are well-established building blocks due to their nutrient-rich composition. Made from high-quality, natural dairy protein, Lactis proteinum is soluble and versatile. It possesses excellent anti-irritant and protective properties and gives an optimal balance of nutrients and moisture to skin and hair.

Lactoferrin is a well-studied glycoprotein that is part of the immune system with antimicrobial, antifungal, and antiviral activities. It is a very effective cure for skin conditions like acne, psoriasis, or diabetic ulcerations. Lactoferrin also boosts the proliferation of dermal papilla cells thus improving hair growth.

Some milk proteins like casein are able to cover active ingredients forming an envelope called a liposome. Liposomes facilitate adsorption through the lipid barrier and also increase the stability of ingredients protecting them from UV radiation and other factors.

Glycomacropeptide another protein from milk enhances the skin lipid barrier and has a significant prebiotic effect on bifidobacteria that improves microbiota balance. Lactis proteinum is a perfect source of amino acids which are natural moisturizing factors (NMF) for the skin binding water and providing volume, firmness, and resilience.
