Cytokines act via binding to a receptor that in turn sends a signal to the recipient cell, leading to a change in function or phenotype. This is especially important in the immune system; cytokines modulate the balance between humoral and cell-based immune responses, and they regulate the maturation, growth, and responsiveness of particular cell populations.
The most current terminology used to describe cytokines is “immuno-modulating agents” or agents that modulate or alter the immune system response. Cytokines are important regulators of both the innate and adaptive immune response.
We now know that daily use of skin care products containing growth factors and cytokines are known to help reduce the appearance of fine lines, wrinkles and improve skin tone and texture.
When used in conjunction with needling or injection they are even more effective than when used in topical creams alone.
