Science

Mechanism of Action

Hydrolyzed Milk Protein works on the skin by forming a breathable, protective film on its surface, which effectively minimizes transepidermal water loss and significantly boosts hydration levels. Its constituent peptides actively stimulate intrinsic skin repair mechanisms, fostering improved collagen synthesis, which contributes to enhanced elasticity and a visible reduction in the appearance of fine lines. Additionally, this ingredient exhibits natural anti-inflammatory properties that calm sensitive and irritated skin, reducing redness. It aids in re-establishing a healthy skin barrier and helps regulate sebum production, balancing both oily and dry skin types to restore the skin's natural hydrolipid film. Its amino acids can also bind to impurities, offering a gentle cleansing effect, and mitigate the dehydrating impact of surfactants.
