What the dermal fillers used for?
Dermal fillers can be used to fix a variety of concerns related to facial aging, including:
- Adding volume and smoothing out the deep creases that run from the nose to the mouth (called nasolabial folds or laugh lines).
- Plumping thin lips and smoothing out vertical lines around the edges of the lips.
- Augmenting cheeks to enhance their shape, often restoring youthful fullness.
- Filling out depressions (hollows) under the eye area.
- Making indented scars from acne or chickenpox more even with surrounding skin.
- Increasing volume to fill out gauntness in the lower cheek or temple area, which most often occurs due to fat pads shifting beneath the surface of the skin.
There are different types of dermal fillers. What are they?
The most popular category of wrinkle fillers is hyaluronic acid. Each type works in a slightly different way with varying results.
Side effects are rare but can include redness, swelling, and bruising at the injection site. The filler may also show up under the skin as tiny bumps. This is a problem that often improves over time.
How long the results last varies from several months to over a year or two. Some research shows that repeated injections may help stimulate the body’s own natural production of collagen. That will help reduce the number of lines and wrinkles. There is also some evidence that less filler is needed overtime to achieve the same look.
Synthetic Wrinkle Fillers
This smaller category of wrinkle fillers includes lab-made substances that are not related to anything found naturally in the skin.
All the fillers in this group have similar side effects, such as redness, swelling, or bruising at the site of the injection. Other side effects include nodules or bumps under the skin that can be seen and felt and that, in rare instances, may require surgery to remove.
The benefits include a longer-lasting effect. And at least one filler offers semi-permanent filling of lines and creases. Remember, products with longer-lasting effects are more likely to cause side effects. And when not used correctly, synthetic wrinkle fillers may cause disfigurement.
Collagen Wrinkle Fillers
Scientists made the first wrinkle fillers from a purified form of collagen extracted mostly from cows. Although it worked well and offered a natural-looking fill, the results didn’t last long. Most collagen injections began to break down as early as 1 month after treatment. Because these wrinkle fillers were made from an animal source, they also had a higher rate of allergic reaction and required allergy testing beforehand.
New ways of processing collagen have helped lower the risks. Plus, new forms of synthetic collagens are making these injections safer and more useful to a wider range of people. Although the results don’t last as long as other wrinkle fillers, many believe the results are more natural-looking.
Side effects of collagen injections include some risk of an allergic reaction (mostly for those still using cow sources), as well as bruising and redness at the site of the injection.
Autologous Wrinkle Fillers
Fat is the most commonly used substance in this category. Your own fat is surgically removed from your thighs, buttocks, or stomach, treated, then injected. You will need to have two procedures (one to remove the fat and one to inject it). Both procedures can be done in one visit. Additional fat purification steps done in the lab can be costly and time-consuming. Results can be semi-permanent, although you may need a series of injections done over time.
