Face exercises can slim your face and strengthen the jawline, some say. But do face exercises actually work? Doctors share what to know about face exercises.
The insulin-like growth factor 1 (IGF-1) receptor is a protein found on the surface of human cells. It is a transmembrane receptor that is activated by a hormone called insulin-like growth factor 1 and by a related hormone called IGF-2. It belongs to the large class of tyrosine kinase receptors. This receptor mediates the effects of IGF-1 ...
As a major growth factor, IGF-1 is responsible for stimulating growth of all cell types, and causing significant metabolic effects. [25] One important metabolic effect of IGF-1 is signaling cells that sufficient nutrients are available for them to undergo hypertrophy and cell division . [ 26 ]
In the 1910s, Eugen Sandow, widely considered to be the first modern bodybuilder in the West, advocated the use of dietary control to enhance muscle growth.

The facial muscles are just under the skin (subcutaneous) muscles that control facial expression. They generally originate from the surface of the skull bone (rarely the fascia), and insert on the skin of the face. When they contract, the skin moves. These muscles also cause wrinkles at right angles to the muscles’ action line. [2]
A growth factor is a naturally occurring substance capable of stimulating cell proliferation, wound healing, and occasionally cellular differentiation. [1] Usually it is a secreted protein or a steroid hormone .
