Most fillers in the market are semi-permanent, nevertheless, equally they tin last from 1 – two years with excellent maintenance and touch ups.
Facial fillers could likewise exist sourced from human, animal, or constructed materials. Knowing the source of the filler helps the dermatologist empathize if the patient needs pre-pare testing. Patients should also be aware what their fillers are made of, equally they may accept preferences against brute products for religious or personal reasons.
In the US, there are more twenty dermal fillers with FDA-approval for use, with Juvederm and Restylane existence the two most well-known brands. Indications range from lip enhancement to the handling of moderate and severe volume loss. Modernistic, soft-tissue filler types include:
one. Hyaluronic acid
Hyaluronic acid (HA) is the most common type of filler in the market, as it's the most natural feeling and looking substance. A hyaluronic acid dermal filler is a clear substance that feels soft and gel-like, derived from purified bacteria and avian products. Hyaluronic acid is a polysaccharide that naturally occuring in the body, ordinarily found in the skin, synovial fluid, cartilage, and other connective tissues. As such, a hyaluronic acid filler is biodegradable, biocompatible, and non-immunogenic; patients aren't required to undergo allergy testing considering the take a chance of HA stimulating an allergic reaction is very low.
HA fillers can replace volume loss and stimulate collagen product, improving epidermal thickness for six – 12 months before the body breaks down the HA molecules. While in that location are a number of HA fillers in the market place, each hyaluronic acrid filler injection differs in viscosity and cross-linking, which makes them suitable for unique injection locations in the pare. Hyaluronic acid is too dissolvable with an injectable enzyme called hyaluronidase, which makes it piece of cake to reverse unwanted results. The elevation HA filler brands are Juvederm and Restylane.
2. Collagen
Collagen is a naturally-occurring protein in the trunk, which serves as the building cake for the skin, bones, tendons, and other tissues. Derived from purified man or bovine collagen products, collagen fillers have been used equally the earliest filler material for the treatment of rhytids. However, collagen fillers have slowly dwindled in popularity, every bit they have the shortest longevity among all filler materials — lasting only 3 – iv months before getting captivated by the body. Cosmoderm, Cosmoplast, Zyderm, and Zyplast are a few examples of collagen-based fillers.
3. Poly-L-lactic acid
Poly-50-lactic acid (PLLA) is a biodegradable and biocompatible synthetic polymer, more commonly seen in medical products like absorbable sutures and bone screws. PLLA fillers are mixed with sterile water to create a hydrogel with a methylcellulose carrier, which are injected in multiple treatment sessions over a few months. Aside from adding volume to the skin and smoothing deep lines, poly-L-lactic acid creates long-lasting collagen stimulating furnishings as it triggers a foreign-trunk reaction amid fibroblasts, which produce collagen fibers to "fight" off the PLLA.
4. Calcium hydroxylapatite
Calcium hydroxylapatite (CaHA) fillers are made up of a biocompatible and non-immunogenic material which is present in man bones and teeth. Equally a filler, synthetic bone microspheres (tiny calcium particles) are suspended in a polish, white carboxymethylcellulose carrier gel and injected with a large needle. With its thick consistency, a CaHA filler can last up to eighteen months. Currently, the merely FDA-approved CaHA filler is Radiesse.
v. Polymethylmethacrylate

Areas To Get A Facial Filler Injection In
Earlier delving into the various injection techniques utilized for cosmetic filler treatment, it's of import to consider which facial regions and conditions tin can be targeted with filler injections. Each area of facial beefcake has its unique concerns, precautions, and challenges, which is why information technology'southward disquisitional to become dermal filler injections from a highly-trained specialist. The 3 main facial regions are the upper face, midface, and lower face.
Upper Face
The upper confront consists of the surface area around the forehead and the optics. While many patients are concerned nigh forehead wrinkles, there is a high level of risk associated with this region. The brow has a vast array of blood vessels. If filler is accidentally injected into a facial artery, information technology may cause vascular occlusion and crusade issues with claret supply. Unnatural looking results may also be produced if dermal fillers are chosen every bit a treatment for this area, every bit the tight pare of the forehead is field of study to extensive motility.
Similar the forehead, filler treatment is also not intended for use in the periorbital region around the eyes. These ii regions are all-time treated with Botox instead. For the upper face, cosmetic fillers can be used to treat a devolumized brow or hollow tear troughs beneath the eyes, as long every bit the correct filler is chosen. Performing a tunnel technique with a cannula also ensures safe rejuvenation.
Midface
The midface region consists of the expanse along the cheeks and around the eyes. The olfactory organ and cheekbones are two major trouble areas, as patients would have unique preferences and specific beauty goals they wish to attain with cosmetic injections. Before proceeding with facial contouring, reshaping, or filling-in, patients should have a comprehensive consultation with their providers. A cheek filler is excellent for lifting the nasolabial fold sagging on each side of the face, too as restoring lost collagen and fat.
Lower face
The mouth, lips, jawline, and chin make upward the lower third of the face, and fillers can be used extensively in this expanse. To keep the jawline and chin proportionate with the rest of the face, a thick, structured filler should be injected deeper into the skin, by the superficial dermis. On the other mitt, thin and fragile fillers tin be used to correct wrinkles and marionette lines around the rima oris.
Although lip augmentation is considered an off-label use for products like Restylane, many providers do inject lip filler into both upper lip and lower lip to volumize thin lips or alter lip shape. However, performing lip injections requires experience, as a heavy hand in injecting tin can lead to a duckbill appearance.

Common Injection Techniques for Facial Fillers
As a cosmetic procedure, fillers are more often than not condom as long as they are injected by a certified medical professional with sufficient experience, training, and know-how in the treatment. Otherwise, it's possible that complications may ascend, such as skin necrosis. Although it rarely happens with fillers, necrosis is an adverse consequence that results from the accidental intravascular injection of filler and causes the death of skin tissue cells due to claret supply failure.
These problems can be avoided with the proper injection techniques. Sure facial regions and treatment cases would crave specific techniques, although nearly facial fillers are administered with a "archetype" combination of tunneling, point, stretching, or dual plane methods, which are used in tandem to care for a single area.
- Tunneling: The tunneling or threading technique is the preferred injection technique among corrective specialists and plastic surgeons. This method is a safe, versatile, precise, and natural way to address superficial skin wrinkles, deeper lines, and areas with volume loss. The needle or microcannula is inserted into the skin post-obit the management of the wrinkle. As the needle is withdrawn from the tissue, the filler product is slowly deposited into the area.
- Signal: As well called the droplet, series, or multi-puncture technique, the point method involves injecting several, small filler aerosol into a deeper layer of the outer skin or right below the skin. Instead of injecting the filler all at once, the microinjection aerosol near each other coalesce to lift wrinkles up. Commonly, this technique is used with a silicone injection to ameliorate the quality of the pare or to fill upwards a large, hollow surface area in a deep identify. The droplet technique is merely used for special cases, as it is susceptible to complications and has the potential to look unnatural.
- Stretching: With the stretching injection technique, it's easier for the injector to place and angle the needle precisely into the target location of the pare. The pare is stretched and put on tension to isolate the target wrinkle. This technique is usually used in areas with pare laxity, like the wrinkles around the rima oris.
- Dual plane: With the dual aeroplane technique, the filler is administered in two different levels of the skin in 1 treatment area. A thin filler is injected into the dermis (the peel's middle layer), then augmented by injections of a thicker filler in the subdermal plane. The dual plane method is used to help patients with superficial wrinkling just deep volume loss, especially in a target area that is constantly moving.
Less common, special injection techniques are:
- Fern pattern: Small amounts of filler are injected in a leaf-shaped design in dynamic facial lines, which helps maintain freedom of movement.
- Cross-hatching: A series of parallel lines are created with a threading technique, which are then crossed with a series of perpendicular lines to treat broader areas.
- Fanning: The needle is placed below the dermis at a certain bending, then passed back and along under the fold to deposit the product slowly and steadily before the needle is withdrawn.
- Depot: Small deposits of filler are placed serially in the treatment area for maximum support.
- Cone/Tower: The needle is inserted perpendicular to the peel until the bone is reached. The filler is deposited in the shape of a pyramid, and more than filler is deposited closer to the bone rather than the skin. This method is usually performed to lift cheek bones.
Needles vs Cannulae: Which Should Exist Used?
While traditional, abrupt needles remind the standard tool for precise, accurate dermal filler placement, more and more than practitioners are utilizing microcannulas to deliver filler products into the treatment site.
Cannulas are long, flexible devices with blunt ends that are attached to the filler syringe. Although they wait like needles, they're far less sharp then there is a lower run a risk of hitting small blood vessels. With the microcannula method, patients are less likely to experience pain, bruising, and bleeding. Downtime and recovery are besides shortened, and the likelihood of vascular occlusion is reduced.
