Lactokine™

Milk protein is obtained from milk through gentle processing of whey or directly from fresh milk, preserving its natural quality and bioactive properties. Rich in essential amino acids and lactic acid, this protein is found in organic extracts of cow’s or goat’s milk, or as native whey protein isolated by microfiltration without repeated pasteurisation. In cosmetics, it is used for its ability to support skin health, having originally been used in traditional preparations for hydration and regeneration. Modern forms include specific fractions such as lactalbumin, which is derived directly from milk and is characterised by a high lactic acid content alongside eight essential amino acids. These proteins are not synthetic but are obtained naturally from milk sources, making them ideal for organic cosmetics.

Milk protein effectively soothes the skin and speeds up the regeneration of irritated or stressed skin. It revitalises the skin, supplies energy to skin cells and stimulates collagen synthesis, helping to smooth the skin. It has firming properties and is therefore effective against signs of ageing. It is particularly effective at maintaining a healthy skin tone, preventing hyperpigmentation by reducing melanin production. Hyperpigmentation is caused by the excessive production of melanin – the pigment that gives skin, hair and eyes their colour. Milk protein helps maintain balanced melanin production. Its mechanisms of action include hydration by binding water in the epidermal layer, restoring the skin barrier by strengthening protein structures, antioxidant protection through essential amino acids and vitamins, gentle exfoliation through lactic acid, and soothing anti-inflammatory properties. Typical concentrations in cosmetics are around 1-5 %, at which it delivers optimal regenerating effects without irritation.

It is particularly recommended for dry, sensitive, dehydrated and mature skin, where it supports hydration and firmness. It is also suitable for irritated or stressed skin following environmental exposure, as well as skin with hyperpigmentation, where it helps regulate melanin. Thanks to its gentle exfoliating properties, it also benefits oily and acne-prone skin without drying it out. Milk protein is suitable for all skin types, but is especially beneficial for sensitive and allergy-prone skin, where it relieves itching and redness.

Studies confirm the effectiveness of milk proteins: whey protein at a concentration of 2 % increased collagen synthesis by 25 % in a culture of human fibroblasts after 48 hours (Journal of Cosmetic Science, 2018). Another study showed that applying milk proteins reduced transepidermal water loss by 30 % in dry skin models (International Journal of Cosmetic Science, 2020). These data support clinical observations of wrinkle reduction and improved elasticity.
