What are dermal fillers?
Dermal fillers help to diminish facial lines and restore volume and fullness in the face.
As we age, our faces naturally lose subcutaneous fat. The facial muscles are then working closer to the skin surface, so smile lines and crow’s feet become more apparent.
The facial skin also stretches a bit, adding to this loss of facial volume. Other factors that affect the facial skin include sun exposure, heredity and lifestyle.
What dermal fillers can do
- Plump thin lips
- Enhance shallow contours
- Soften facial creases and wrinkles
- Improve the appearance of recessed scars
- Reconstruct contour deformities in the face
- Decrease or remove the shadow of the lower lids
Dermal fillers can be very helpful in those with early signs of aging, or as a value-added part of facial rejuvenation surgery.
What dermal fillers can’t do
For some patients, surgery such as a facelift, brow lift or eye lift may be the best approach. Minimally invasive rejuvenation treatments, such as soft tissue fillers, cannot achieve the same results, but may help delay the time when consideration of a facelift becomes appropriate. It is important to remember that dermal fillers are temporary treatments for facial aging and that ongoing treatments will be needed for long-term results.
Who is a good candidate for dermal fillers?
You may be a good candidate for dermal fillers if you:
- Are physically healthy
- Don’t smoke
- Have a positive outlook and realistic goals in mind for the improvement of your appearance
- Are committed to maintaining good skin health
For some patients, surgery such as a facelift, brow lift or eye lift may be the best approach.
What are the steps of a dermal fillers procedure?
A dermal fillers procedure includes the following steps:
Step 1 – Facial assessment & mapping
If you choose to utilize packaged soft tissue fillers, the plastic surgeon, or his specially-trained nurse, will evaluate your facial appearance and skin tone and examine the areas of your face to be augmented.
Strategic points on your face may be marked as the appropriate injection sites for the filler. Photographs may be taken of the areas to be treated.
Step 2 – Cleansing & anesthetizing
The injection sites will be cleansed with an antibacterial agent.
Pain at the injection site may be ameliorated by use of a very cold instrument to chill the skin, anesthetic ointment to numb the skin or injection of local anesthesia.
While not painless, the injections are usually easily tolerated.
Step 3 – The injection
Injection usually takes only a few moments per site. The process of injecting, massaging, and evaluating the result is performed, and additional filler added as needed.
Depending on the number of areas to be treated, the whole process may be as short as 15 minutes, or as long as an hour.
Step 4 – Clean up & recovery
Once the results are deemed satisfactory, any markings will be cleansed off.
You may be offered an ice pack to reduce swelling and alleviate discomfort. Although the area may feel a bit tender for a day or two, it is usually not painful enough to require any medication.
Calcium hydroxylapatite
Brand names include: Radiesse
Calcium hydroxylapatite is found naturally in human bones and is a mineral-like compound. It’s often used to:
- Moderate-to-severe creases such as nasolabial folds, marionette lines and frown lines
- Enhance fullness of the cheeks and other facial contours
- Improve volume in areas of facial wasting such as can occur in HIV-positive people taking certain medications
Calcium hydroxylapatite is biosynthetically produced, which means that no animals or animal products are used. This lowers your risk of an allergic reaction and no skin testing is required. This type of dermal filler is known to produce a very natural result, doesn’t migrate and side effects are rare. This dermal filler was first used in dentistry and reconstructive surgery and has a long safety record.
Brand names include: Captique, Esthélis, Elevess, Hylaform, Juvederm, Perlane, Prevelle, Puragen, Restylane
Hyaluronic acid injections can be used to improve the skin’s contour and reduce depressions in the skin due to scars, injury or lines. You can see potentially dramatic improvements for:
- Acne scars
- Cheek depressions
- Crow’s feet at the corner of your eyes
- Deep smile lines that run from the side of the nose to corners of the mouth (also known as nasolabial furrows)
- Frown lines between the eyebrows
- Marionette lines at the corners of the mouth
- Redefining lip border
- Scars including burns, acne and those caused by wounds
- Smoker’s lines; vertical lines on the mouth
- Some facial scars
- Worry lines that run across your forehead
Hyaluronic acid is a natural substance found in your body. High concentrations are found in soft connective tissues and in the fluid surrounding your eyes. It’s also in some cartilage and joint fluids, as well as skin tissue. It is extracted and reformulated and now has become one of the most popular kinds of injectable fillers. If the term sounds familiar, it’s because the same substance is often injected into the aching joints of people with arthritis to ease pain and provide extra cushioning.

Brand names include: Aquamid
Polyalkylimide is a semi-permanent dermal filler and is often used by plastic surgeons to:
- Treat deeper wrinkles such as nasolabial folds or depressed scars
- Plump thin lips
- Enhance cheekbones and the jawline, and to replace facial volume lost due to age
- Treat facial wasting from HIV medications
Polyalkylimide has very little reaction with human tissue, meaning it’s biocompatible, and no allergy test is required. It is radio transparent, meaning it won’t interfere with x-rays.
After the injection, a thin layer of collagen slowly forms around it over the course of about a month. The gel is eventually completely surrounded. A single procedure can inject large volume. This product, which is thought to be quite stable over time, can even be removed if necessary.
Polylactic acid
Brand names include: Sculptra
Polylactic acid is a synthetic dermal filler that is injected into your face, causing your body’s own production of collagen. This type of dermal filler is known as a stimulator. This non-toxic, biodegradable substance has been used for more than 40 years as suture material.
Polylactic acid is known to work particularly well in the lower half of your face, and is used to:
- Fill the lines caused by laughing
- Plump thin lips
- Treat deep nasolabial folds
This substance is unlike other dermal fillers because it doesn’t produce immediate results. Instead, it stimulates your own body’s collagen production, so results appear gradually over a period of a few months.
You will likely need about three monthly treatments to achieve your desired results. With each treatment, there is re-stimulation of your own collagen. Then it can take four to six weeks to see the full effect. While this type of dermal filler is considered semi-permanent, you may still need occasional touch-ups.
Polymethyl-methacrylate microspheres (PMMA)
Brand names include: Bellafill
PMMA is considered a semi-permanent filler and is most often used to treat medium-to-deep wrinkles, folds and furrows, particularly nasolabial folds. It can also be used to fill out pitted scars and to augment thin lips.
When a more permanent solution to facial wrinkles is desired, PMMA is often used instead of collagen replacement therapy or hyaluronic therapy. PMMA has been used for many years in permanent surgical implants. Because of this, your surgeon will likely under-fill on the first treatment, adding more later if needed.
One of the downsides of PMMA is that a number of injections are needed to create volume and it can take up to three months to realize the full effects. It may also be visible under the skin. To avoid any unwanted results, it’s key that your plastic surgeon is familiar with the proper technique, which involves injection at the dermal subcutaneous junction using threading or tunneling methods.
