Hyaluronic acid is a naturally-occurring sugar molecule that can be found in the sub-dermal layers of the skin. The fact that hyaluronic acid is a natural ingredient compatible with the human body means that fillers with hyaluronic acid are generally safer than other types.
Hyaluronic acid based products are considered one of the safest in dermal fillers, particularly those made from synthesized HA, which is made in bacteria instead of using human or animal tissue.
Polylactic acid is a synthetic dermal filler that is injected into your face, causing your body's own production of collagen. This type of dermal filler is known as a stimulator. This non-toxic, biodegradable substance has been used for more than 40 years as suture material.
There's only one FDA-approved dermal filler that is not absorbed by the body. It is made with polymethylmethacrylate (PMMA) beads suspended in a solution that contains bovine (cow) collagen. PMMA beads are tiny round, smooth, plastic beads.
Unapproved Dermal Fillers
The FDA is warning health care providers and patients not to use any Juvederm Ultra 2, 3 or 4, because these products are not approved for use in the U.S. As such, the safety and effectiveness of these products cannot be assured.
Not only can super serums, retinols and treatment kits help to erase lines like botox, and hand-held tools help to sculpt like fillers, but more and more technology is available to mimic results of in-clinic machines too.
The major contraindications to the use of a filler are as follows: active infection near the site of injection, a known allergy/hypersensitivity to the material or to the lidocaine mixed in the syringe of the filler (Zyderm, Zyplast, Cosmoderm, Cosmoplast and certain hyaluronic acid fillers and Artefill) and glabellar ...
Depending on the filler used, you can enjoy a younger looking face for 2 years but that should depend on your priorities. The results of either of the aforementioned fillers can vary from one person to the next.
The effects of the fillers will wear off after months or years, but the treated area is likely to return to its original state. The benefits of both Botox and fillers will be gone and you'll notice that those lines and volume loss will come back.
Hyaluronic acid is the most common natural filler. Hyaluronic acid is also known as extracellular matrix. It is a gel-like material which is found normally in the body and is the consistency of a thick gel.
Hyaluronic acid (Juvederm, Restylane) and polylactic acid (Sculptra) are two types of dermal fillers recommended for use in the cheek and under-eye area. These types of dermal fillers are temporary. Other fillers, such as Radiesse (hydroxylapatite), are also used off-label for this area.
Restylane is more granular, while Juvéderm is smoother. For this reason, Juvéderm is often used to address finer lines and wrinkles in tighter areas of the face such as the smile lines. Restylane – which stays in place better when injected – may be more adept at adding volume to sunken areas of the face.
Dermal fillers carry the possibility of more risks and side effects than Botox. Severe side effects are rare. Moderate side effects usually go away within two weeks. However, serious adverse effects have been connected to the use of unregulated, needle-free injection devices for dermal filler procedures.
Hyaluronic acid (HA) fillers are one of the most popular as they have a soft texture to create beautiful results. HA is found naturally in your body, so they dissolve naturally and gradually over time, generally between 6 to 12 months depending on the individual and the product used.
With today's cosmetic technology, patients of all ages can have facial rejuvenation with injectables. The primary aim for patients over 60 is to soften lines while maintaining natural-looking results.
Fillers are a great option for patients seeking a softer, more youthful look. However, if used improperly or over used, fillers can have negative long term consequences. In fact, patients who do not properly use filler could actually speed up their skin's aging process, resulting in older looking skin.
Many plastic surgeons say that Juvederm and Restylane are the most durable and longest-lasting fillers available. Both contain hyaluronic acid and are good for smoothing wrinkles and lines. Hyaluronic acid carries 1,000 times its weight in water and makes the skin look young, supple, and soft.
1 to 2 Years
Some dermal fillers have been studied to last close to two years. The three fillers that tend to last the longest are Restylane Lyft, Restylane Defyne, Restylane Refyne, Juvederm, Voluma, Radiesse, and Sculptra. Restylane Defyne is built for balance and used in the nasal labial folds and marionette lines.
If you love the look of your fillers, you'll have to keep going back for more. After about six months, the hyaluronic acid fillers are naturally broken down by the body. So, you have to get touchups once or twice a year to maintain the look.
The incidence of ischemic complications in HA fillers is about 0.3%. Tissue necrosis is best prevented by thorough knowledge of facial vascular anatomy and meticulous technique. Necrosis occurs due to arterial or venous obstruction.
Although dermal fillers are generally thought to be safe, all foreign materials have potential ability to cause adverse reactions. HA is composed of polysaccharides and has same structure in all species; therefore, the risks of an implant rejection or an immune response are low.
