Injections of dermal fillers have undergone numerous alterations over the years. Since the development of the syringe in the 1800s, a wide variety of dermal fillers, both organic and synthetic, have been developed and improved.
Paraffin was one of the first materials utilized as dermal fillers. Although it was employed for augmentation, the unrefined material had many drawbacks. Since then, researchers have worked to create dermal fillers that are both safer and more effective. Bovine collagen was the first dermal filler to receive FDA approval for cosmetic use in 1981. Other varieties with differing degrees of effectiveness, safety, and duration have entered the market over the past 40 years.
Types of Dermal Fillers
- Hyaluronic acid filler – The most popular kind of dermal filler on the market right now is this one. It is accessible, safe, adaptable, and may be made in a variety of concentrations to treat a variety of distinct cosmetic issues. A naturally occurring substance of the connective tissue of the skin is hyaluronic acid. As a result, it integrates readily into the body and is regarded as quite safe.
The fact that it can be readily reversed adds to its safety. The availability of hyaluronidase, a naturally occurring enzyme that can be used to remove hyaluronic acid, makes it easier to correct issues with the dermal filler. If it becomes necessary to take the fillers out, say when the patient develops vascular blockage, the filler can be promptly removed by injecting hyaluronidase into the affected area.
The lifespan, appearance, and safety of dermal fillers were further enhanced by a more recent version of hyaluronic acid known as NASHA, or non-animal stabilized hyaluronic acid, which was produced from cultured bacteria rather than animal sources.
Its adaptability stems from the fact that its molecular composition and concentration may be adjusted, enabling more specialized treatments for wrinkles and lines in various areas of the face. The duration of the effect might vary greatly depending on the quantity or makeup of the hyaluronic acid, although it typically lasts between six months and two years.
- Calcium Hydroxylapatite – Compared to hyaluronic acid fillers, this filler is usually more viscous and offers greater structure. It is typically not utilized for fine lines and shallow wrinkles due to its consistency. Most commonly, it is used to contour, particularly along the jawline. Additionally, deeper wrinkles and skin creases can be treated with it, along with sunken cheeks to add volume. It is regarded as a safe dermal filler because it is also naturally present in the body. These kinds of fillers typically stay longer since the human body degrades calcium more slowly than hyaluronic acid. When used for contouring, it often lasts up to a year, and when used as a filler for deep wrinkles and folds, it typically lasts up to three years.
- Poly-L-lactic acid (Sculptra) – This kind of filler is frequently used to replace lost facial volume brought on by aging or illness. It uses Poly-L-lactic acid rather than hyaluronic acid to support and give the skin structure. In addition to filling out the skin, it stimulates the creation of collagen, which adds even more volume. The collagen will replace the PLLA structures as the poly-L-lactic acid is broken down over time into water and carbon dioxide and is metabolized by the body, adding and preserving facial volume. Because this process takes months, the results look natural. Following an evaluation of the areas in need of volume, PLLA is successively injected into these regions. The effects typically persist two years after injection.
There isn’t a single “optimal” form of dermal filler due to the variety of alternatives available. Each of them has advantages and disadvantages, so seeing your dermatologist is the best way to figure out which is best for you. Dermal fillers are non-invasive cosmetic procedures, but since their effects and potential hazards can last for years, it’s important to thoroughly explore them with an expert to receive the maximum benefit.
