Dermal fillers for the face are a gel-like material of varying density, which are injected under the skin with the finest needles. They are used in modern cosmetology to correct fine, medium, deep wrinkles, smoothing nasolabial folds, filling the atrophic scars. In addition, the gel is injected to raise the corners of your mouth, change the shape of the chin, cheekbones, and cheeks. The fillers have a thick, viscous, plastic consistency, a stable structure, capable of holding shape for a long time without breaking. Their main purpose is rejuvenation and modeling of the face. They are injected into problem areas where it is necessary to smooth out creases in the face or add volume. What to choose – a biologically compatible material with the human body or a collagen method of correction? Before you go for the procedure, it is worth finding out What are Dermal Filler products.
Types and features
In the middle of the last century, facial filler was an implant made of completely synthetic components: silicone and paraffin. Although the implant gave no allergic reactions due to the absence of toxins and animal proteins and provided a good visual effect, over time, patients developed granulomas – thickening resembling nodules at the injection site. The body often reacted to silicone as a foreign body, rejecting it. Silicone is biodegradable, which means it is not eliminated from the body naturally. The implant does not resorb, sometimes migrating from one area to another. Today, silicone implants are considered obsolete.
In the 70s, silicone was replaced by collagen injections, and in the 90s, biodegradable materials of hyaluronic acid were actively introduced, which is now considered a recognized leader among the preparations. The new generation preparations can have different densities, allowing the selection of options for thin and thick skin, different concentrations of the main active substance. There are gel products that are injected superficially (intradermal) and in deeper layers. If you want to know more about filler injections, what they are and which option is right for you, you should make an appointment with a cosmetic surgeon.
All facial modeling products can be divided into several categories:
- Hyaluronic or biodegradable – the most common option because of its high efficiency, affordable cost, safety for the body. Even if allergic reactions, complications, or patient dissatisfaction with the obtained result, the substance is easily destroyed. The antidote for the polysaccharide is the enzyme hyaluronidase.
- Biosynthetic consists of chemicals that do not have analogs in the body but are maximally compatible with it. This group includes products based on purified animal collagen, calcium hydroxyapatite, poly-L-lactic acid, polymethyl methacrylate microspheres.
Biodegradable hyaluronic materials for contour plastics are considered to be the most common and safe today. The method of injecting the product is quite simple, so they are often used in clinics.
