As we age, the effects of age, heredity, sun, gravity and lifestyle take their toll on the skin of the face and body. The face, being the most exposed part of the body, is the part where skin changes are most noticeable, and it is the part that everyone worries about first in an attempt to maintain a youthful appearance. In this article, we will try to explain what are injectable fillers, their uses and results.
Facial changes are obvious. Wrinkles and creases develop further as the underlying subcutaneous tissue thins and there is a loss of volume and fullness. Another reason for the formation of wrinkles and folds in the facial skin is the continuous or frequent use of the skin expression muscles. Initially, the use of these muscles leads to the formation of dynamic wrinkles that disappear. When the muscles of that particular part of the face relax. This leads to the formation of so-called expression lines or glabellar wrinkles. (Between the eyebrows), forehead wrinkles (horizontal lines on the forehead looking upwards, also called surprise wrinkles) and goose bumps (wrinkles radiating from the eye creases).
Eventually, these dynamic wrinkles become more permanent and remain even when we relax our expressive muscles. Think of a sheet of paper that is folded and unfolded several times. Over time, the initial slight crease becomes permanent and prominent.

The upper face is not the only part of the face that age affects and the other factors mention above. Moving down we see the nasolabial folds. The deep furrows that run from the sides of the nose to the corners of the mouth. Also, starting from the corners of the mouth, almost in the same direction as the nasolabial folds are the marionette lines. And they are know as this because these lines give the person the appearance of a marionette.
The solution to these problems is a simple, relatively inexpensive and safe injection of a gel-like substance called a facial filler or dermal filler into the area under the skin. So what are injectable fillers. It is an Injection of this volume under the skin will cause the skin to swell and regain lost fullness, while wrinkles or folds in the overlying skin will become shallower to the point of disappearing.
These fillers are useful not only to eliminate folds and wrinkles, but also to increase the volume of the face and other parts of the body. We can change the shape of the nose for those who have a flat nose, enlarge the cheekbones for those who have sunken cheeks, enlarge the lips for those who want larger and sexier lips, or enlarge the chin for those who have sunken cheeks and a smaller chin than desired. Fashion trends change and fillers can be use to enlarge body parts desire by the fashion of the moment. When lowering the body, the breasts can be augment with fillers or the buttocks to increase the perception of sensuality.
Ideally, the injected substance should be safe for the human body and should not cause any side effects, should have a chemical composition as close as possible to the substances naturally present in the skin and should be able to last. From a technical point of view, many formulas have been introduced in recent years to try to approach this ideal situation. What are injectables fillers will be describe below
