Dermal

The second main category of injectables is classified as dermal fillers (also known as soft tissue fillers). This category of injectables is designed to “fill in” wrinkles and lines that are visible while the facial muscles are at rest. Dermal fillers target the mid dermis to restore lost volume to these wrinkles and lines, but can also be used to add additional contouring to other targeted areas, such as hollowness in the cheekbones or plumpness in the lips.

There are numerous dermal fillers available on the market.

The most common fillers, such as Juvéderm and Restylane, are composed of hyaluronic acid, which is a substance naturally produced in the skin. This substance is known as “nature’s moisturizer,” and binds moisture 1,000 times its own weight in water in order to keep the skin plump and hydrated. These fillers are soft and gel-like in appearance, and allergy testing for these fillers is usually not needed. Results last between 6-12 months on average before the body naturally breaks them down, and they are often infused with lidocaine to reduce discomfort during and after the treatment. Higher levels of hyaluronic acid in the body lead to more skin hydration, joint lubrication, inflammation protection, and better immune regulation. These fillers are recommended for patients who are newer to fillers, and are completely reversible via the use of a special solution that can break down the filler instantly.

Some fillers, such as Radiesse, are based on calcium hydroxylapatite, which is a substance that is naturally found in the bones. These particles are almost microscopic and are contained in a smooth gel that is a bit thicker than fillers based on hyaluronic acid. As a result, they last a bit longer – usually around 12 months or longer on average. These types of fillers have the benefit of stimulating natural collagen production, which makes them a great option for lines and wrinkles that are very deep in the skin. Because calcium hydroxylapatite is found in the bones, these fillers are also a great option for improving volume loss in the hands as well.

Fillers such as Sculptra Aesthetic are based on poly-L-lactic acid, which is a biodegradable synthetic filler based on a natural substance produced by the body after exercise and other active movements. This substance has been used medically for many years, such as in dissolvable stitches. These kinds of fillers are collagen stimulators, and help your skin naturally rebuild collagen in order to smoothen fine lines and wrinkles that are embedded a bit deeper in the skin. While the gel dissipates a few days after treatments, the results can last 2 years or more on average.

Firmer fillers are suitable for areas such as the cheekbones and temples, whereas some of the more flexible fillers re used for areas that have movement during expression, such as the nasolabial folds.
