What are Dermal Fillers?

What are Dermal Fillers?

Have you heard of dermal fillers? Chances are, you probably have. These injectables have gained massive popularity in the last decades. Since 2000, dermal filler usage has increased 274%, according to the American Academy of Plastic Surgeons. But what exactly is a dermal filler? If you’re looking for more information, look no further. We’ve pulled together a guide to help if you’re considering dermal filler injections.   

What are dermal fillers? 

Dermal fillers are minimally invasive cosmetic injections. They are common aesthetic procedures that usually last anywhere from 6 to 18 months. Dermal fillers contain FDA-approved substances. This plumps the skin, usually with naturally occurring substances like hyaluronic acid.  When injected, these substances smooth fine lines and wrinkles. By plumping the skin, filler can also address volume loss. Volume loss is usually a side effect of aging, when the skin doesn’t produce as much collagen. The most common injection areas are the lips, brow area, smile lines, forehead and chin. Some fillers may also be used on the neck and hands. 

What types of fillers are there? 

Dermal fillers can contain a variety of substances. All are FDA-approved but work in different waysWhile some are natural, others are lab manufactured. At Loven Aesthetics, we use hyaluronic acid fillers. Here are some of the most common filler substances.  

  • Hyaluronic acid is a naturally occurring substance in the body. It works to add plumpness to the skin and help keep the skin hydrated. Juvederm and Restylane are both hyaluronic acid injections.  
  • Calcium hydroxyapatite is a mineral-like substance. It is found in bones and used to correct volume loss and moderate to severe wrinkles. The most common brand name calcium hydroxyapatite is Radiesse
  • Polyalkylimide is a transparent gel injection.  
  • Polylactic acid stimulates collagen growth to smooth fine lines.  
  • Polymethyl-methacrylate microspheres (PMMA) is a semi-permanent “mircrosphere” filler.  


Is Botox a dermal filler? 

A common misconception is that Botox is a filler. While Botox and dermal fillers are both injectables, they work in different ways. Botox is a muscle paralytic derived from the purified form of botulinum toxin. You might have also heard it called a neurotoxin. It works by blocking nerve signals and “freezing” the muscles. This reduces the appearance of lines and wrinkles. In contrast, dermal fillers, also sometimes called soft tissue injections, add materials. By injecting these substances, dermal fillers add fullness and plumpness to the face.  

What should I expect? 

There is usually no special preparation needed for dermal filler injections. Always be sure to tell your doctor of any medications you may be taking. Your doctor may ask you not to take aspirin or other anti-inflammatory medications before your appointment. Before your injection you be receive a topical numbing gel or a local anesthetic may be in the injection. After your injection, you may have an “overfilled” appearance. This is normal swelling and will usually subside in a day or two. Sometimes, bruising and redness may occur but usually goes away. Some other less common possible side effects include: 

  • Temporary numbness 
  • Palpable lumps or hard areas 
  • Hypersensitivity  


When scheduling your injections, be sure to consider your plans. Bruising, swelling or redness may not always occur. But it’s best to consider possible side effects when planning events. You should avoid any vigorous activity for a day or two to ensure the injection site heals. Your provider can help you determine how often you should have injections based on your skin and goals.  Each patient is unique, so length of effect varies for everyone.
