BOVINE COLOSTRUM: FROM NUTRITION TO DERMAL THERAPY

Colostrum is the first secretion of milk after delivery, which contains a variety of bioactive molecules such as immunoglobulins, growth factors, vitamins and minerals. Bovine colostrum (BC), also referred to as “liquid gold,” contains higher levels of proteins, cytokines and antimicrobial peptides when compared with mature milk. These constituents help support the neonatal immune system, healing of tissues and cellular growth. In cosmetics, BC exhibits a number of advantages, including: anti-ageing effects through an increase in collagen synthesis and prevention of telomere loss; increased skin elasticity as a result of improved hydration by hyaluronic acid released from nylon/BC films and antibacterial effect via action of lactoferrin and lysozyme, which helps to fight acne and infection. BC also promotes wound healing and antioxidant activity against reactive oxygen species. In addition, hydrolysed colostrum extract is also said to work effectively in skin lightening by controlling melanin production. As a therapeutic, industrial use of the approach may be limited by stability and standardisation. Further investigation and better formulation approaches will make BC a versatile ingredient for effective and natural skin care agents.
