While more complex than fat grafting by injection, direct placement of a custom-prepared silicone implant requires only a single treatment to yield a permanent result. Other synthetic materials may also be used.

The implant is introduced through several small incisions hidden in the hair of the scalp and placed just above the bone.

It can cover the entire width and breadth of the forehead down to the eye sockets or be made smaller to address localized depressions.

The implant is shaped to convert a flat or sloped bony contour to more of a convexity, thus adding an element of depth to the upper third of the face.

Initial recovery takes about two weeks, while final healing takes up to six months.
