Dermal Fillers
In the realm of aesthetic
medicine, dermal fillers have emerged as a popular non-surgical option for
those seeking to rejuvenate their appearance. These injectable treatments can
address a variety of cosmetic concerns, from smoothing fine lines and wrinkles
to restoring volume and enhancing facial contours. This guide aims to provide
an in-depth look at what dermal fillers are, how they work, and what one can

What Are Dermal Fillers?
Dermal fillers are gel-like substances that are injected beneath
the skin to restore lost volume, smooth lines, soften creases, or enhance
facial contours. They are primarily used to treat facial wrinkles and folds,
provide lip augmentation, and improve the
appearance of scars. The most common types of dermal fillers are based on
substances that are naturally found in the body, such as hyaluronic acid.
Types of Dermal Fillers
1. Hyaluronic Acid (HA) Fillers: HA is a naturally occurring
substance in the skin that helps to keep it plump and hydrated. HA fillers,
such as Juvederm and Restylane, are popular due to their natural-looking
results and safety profile. They can last anywhere from six months to two
years, depending on the specific product and treatment area.
2. Calcium Hydroxylapatite: Found in products like Radiesse,
this filler is heavier and often used to treat deeper lines and wrinkles. It
also stimulates natural collagen production, offering long-lasting results that
can persist for up to a year or more.
3. Poly-L-lactic Acid: This biodegradable synthetic substance,
marketed under the brand name Sculptra, works by stimulating collagen production. It is used to treat
deeper facial wrinkles and can provide gradual, lasting results over a period
of several months.
4. Polymethylmethacrylate (PMMA) Beads: Found in products like
Bellafill, PMMA is a semi-permanent filler that provides long-lasting results.
It consists of tiny beads that remain in the skin indefinitely, providing
ongoing support.
How Do Dermal Fillers Work?
Dermal fillers work by adding volume to the skin and underlying
tissues. The specific mechanism depends on the type of filler used. For
instance, hyaluronic acid fillers attract and retain water, which helps to keep the skin hydrated and plump.
Other fillers, like calcium hydroxylapatite and poly-L-lactic acid, stimulate
collagen production, which provides structural support to the skin over time.
