Artificial methods Edit. For crystallization (see also recrystallization) to occur from a solution it must be supersaturated. This means that the solution has to contain more solute entities (molecules or ions) dissolved than it would contain under the equilibrium (saturated solution).
The egg white can be used to instantly tighten the skin on the face and neck. Apply a very thin layer for an instant face lift. Do not wash off; the protein will hydrate the skin as well and egg whites have no distinct smell.
Newer non-surgical technology helps tighten the skin by focusing controlled radiofrequency energy on the deeper layers of the skin. This warming of the tissue stimulates collagen growth at the level which causes tighter firmer skin. The device and technology can be used to tighten the face/jawline/neck area as well as contour areas of the body such as the arms, upper thighs, knees, and abdomen.
