What are dermal fillers?
Dermal fillers are injectable treatments used to restore lost volume, smooth out wrinkles, and enhance facial contours. As we age, our skin loses collagen, elastin, and fat, which can lead to sagging, hollow areas, and the formation of lines and creases. Dermal fillers help reverse these signs of aging by filling in the areas where volume has been lost or by enhancing features like the lips, cheeks, chin, or jawline. Fillers are not the same as Botox. While Botox relaxes muscles to reduce movement-related wrinkles, fillers add structure, lift, and fullness to static areas.

What types of dermal fillers exist?
There are several types of dermal fillers, each with different properties and uses. The most common and widely used fillers are made from hyaluronic acid (HA), a naturally occurring substance in the skin that holds moisture and keeps tissues hydrated and plump. Popular brands in this category include Juvederm, Fillmed, Teosyal, and Belotero. These fillers are soft, reversible, and versatile.
Other types include calcium hydroxylapatite (CaHA) fillers, such as Radiesse, which provide a firmer structure and stimulate collagen production, making them ideal for deeper wrinkles and facial contouring. Poly-L-lactic acid (Sculptra) is another filler that also stimulates collagen, but works gradually over time, making it suitable for overall facial volume restoration. Lastly, polymethylmethacrylate (PMMA) is a semi-permanent filler used in specific cases but less commonly due to its long-term nature.
Each type of filler is chosen based on the patient’s goals, the area being treated, and how long the results are expected to last.
What areas can be treated with dermal fillers?
Dermal fillers are highly versatile and can be used to treat a wide range of facial areas for both rejuvenation and enhancement. Some of the most common treatment areas include:
Cheeks: Fillers can restore volume lost due to aging or weight loss, lifting the mid-face and creating a more youthful contour.
Nasolabial folds: These are the deep lines that run from the sides of the nose to the corners of the mouth. Fillers soften their appearance, making the face look more refreshed.
Marionette lines: These lines run downward from the corners of the mouth and can create a sad or tired expression. Filler helps smooth these lines and supports the lower face.
Lips: One of the most popular areas for filler, the lips can be enhanced for volume, shape, symmetry, and definition—while still looking natural when done properly.
Chin: Chin fillers improve the profile, correct a weak chin, or create a more balanced face shape without the need for implants.
Jawline: Fillers can define the jawline, reduce jowling, and improve facial proportions, especially when paired with chin contouring.
Under-eyes (tear troughs): This delicate area often appears hollow or dark with age. A specialized filler can restore volume and brighten the area, but it must be done by experienced hands due to the thin skin and complex anatomy.
Temples: Hollow temples can make the face appear gaunt or aged. Filler can subtly restore fullness and lift the outer brows.
Nose (non-surgical rhinoplasty): Fillers can be used to smooth small bumps, improve symmetry, or create the illusion of a straighter, more refined nose.
Each area requires a unique approach, and your practitioner will assess your facial structure and goals to recommend the right product and technique. Not every filler is suitable for every area—so choosing a qualified injector is key to getting safe, natural-looking results.
What are the benefits of dermal fillers?
Dermal fillers offer many benefits for both rejuvenation and enhancement. They can restore youthful volume to areas that have hollowed with age, such as the cheeks or temples, and smooth deep folds like the nasolabial lines around the mouth. Fillers can also be used to subtly enhance facial features, such as adding shape and definition to the lips, chin, or jawline.
The results are immediate, customizable, and non-surgical, making them a popular choice for people who want natural-looking improvements without downtime. Another benefit is that treatments are relatively quick, often taking less than 30 minutes, and results can last from 6 months up to 2 years depending on the type of filler used and the area treated.
What are the pre-treatment and after-treatment instructions?
Before getting dermal fillers, it’s important to follow a few guidelines to reduce the risk of bruising and swelling. Avoid taking blood-thinning medications and supplements—such as aspirin, ibuprofen, vitamin E, fish oil, and alcohol—for about 3 to 5 days before the procedure, unless prescribed for medical reasons. Stay well-hydrated and arrive with clean skin, free of makeup. If you’ve had any history of cold sores and are having filler around the lips, your provider may prescribe an antiviral to prevent a flare-up.
After the treatment, avoid touching or massaging the treated area unless instructed to do so by your provider. Refrain from heavy exercise, saunas, steam rooms, or alcohol for at least 24 hours, as these can increase swelling or bruising. Apply a cold оr hot compress gently if needed, and sleep with your head elevated the first night. Full results may take a few days to settle, and a follow-up appointment may be scheduled to ensure optimal symmetry or touch-up if needed.
What are the risks of dermal fillers?
Dermal fillers are considered safe when administered by qualified professionals, but like all medical treatments, they carry some risks. Common side effects include swelling, redness, tenderness, bruising, or mild asymmetry, which are usually temporary.
Rare but more serious risks can include vascular occlusion, where filler accidentally blocks a blood vessel. This is a medical emergency and requires immediate treatment to avoid tissue damage. Infection, allergic reactions, lumps, and over- or under-correction are other potential complications. The risk of these issues is minimized when fillers are administered by trained practitioners who understand facial anatomy and proper technique.
Reversible fillers like hyaluronic acid can be dissolved with an enzyme called hyaluronidase if necessary, which provides an added layer of safety.
