Facial aging is one of the areas most studied by plastic surgery. Therefore, in recent years numerous surgical treatments and aesthetic procedures have been developed and refined to reverse this process, such as fillings. Time marks are often relentless on the face and the pursuit of rejuvenation arouses great expectation of change in patients.
Facial rejuvenation encompasses a series of surgical techniques associated with less invasive procedures that seek to reposition ptosis (drooping) facial tissues and attenuate the time marks on aged and photoaged skin.
Facial aging involves a number of changes in the face, such as creases and wrinkles due to loss of elasticity and turgor of the skin. Over the years, these creases, wrinkles become more evident, and the substances used in the filler act to alleviate such depressions, making the face younger and smoother. Another major use of fillers is increased projection of regions of the face such as lips and cheeks.
The main methods used by plastic surgeons in filling are autogenous fat (obtained from the patient's liposuction) and hyaluronic acid. Check out the characteristics of each:
Autogenous fat grafting
It has the advantage of being a natural substance of the patient, being less subject to inflammatory reactions. The filling can be associated with a facelift surgery that corrects the cervical fat (called the double chin), using the liposuction fat in the regions to be filled. In general, it has some degree of absorption after grafting, which varies between 10-30%, depending on the amount used.
It is a synthetic substance composed of a polymer with good biocompatibility and lower index of inflammatory reactions. This biocompatibility is because hyaluronic acid is a natural component of connective tissues. It can be applied in the office itself, with local anesthesia, and is contraindicated for pregnant patients with active cold sores. After its use, the patient may return to his usual activities, being advised only not to perform heavy physical activities on the day of application.
Hyaluronic acid is more widely used than fat because it can be used on deeper creases, superficial wrinkles or on lips and cheeks. Its duration varies from 8 to 12 months, depending on some factors such as skin type, age of the patient and even life habits, presenting very low complication rate, such as excessive edema and redness in the applied site, usually reversed after 24h. At the end of the action of the product, which is absorbed by the body, other applications can be performed.
• Product rejection;
• Allergy to the product;
• Appearance of nodules;
• Late edema.
The result of facial fillings, as in all cosmetic surgeries, will depend on the reaction of the patient's body and zeal with pre and postoperative indications.
