Restylane, invented in a Swedish laboratory and first used in the United States, has been injected 10 million times worldwide and remains the leading dermal filler. It is typically used to fill hollows under the eyes, lips, and lip folds (lines around the nose and mouth). Hyaluronic acid (HA) fillers are among the most popular due to their soft texture and ability to create beautiful results. HA is naturally occurring in the body, so it dissolves naturally and gradually over time, usually between 6 and 12 months, depending on the individual and the product used.
Allergan's Juvéderm line is one of the most well-known HA fillers. They are also the manufacturer of Botulinum toxin wrinkle treatment Botox, as well as several models of the most commonly used silicone breast implants. It can be said that Allergan dominates much of the cosmetic enhancement market. Juvéderm is a natural and biodegradable product, as is Galderma's Restylane and its family of competitive HA dermal fillers.
Calcium hydroxylapatite is biosynthetically produced, meaning no animals or animal products are used. This reduces the risk of an allergic reaction and skin tests are not required. This type of dermal filler is known to produce a very natural result, does not migrate, and side effects are rare. This dermal filler was first used in dentistry and reconstructive surgery and has a long history of safety.
Polyalkylimide has very little reaction with human tissue, making it biocompatible and no allergy test is required. It's radio-transparent, meaning it won't interfere with X-rays. Polylactic acid is a synthetic dermal filler that is injected into the face and causes the body's own production of collagen. This type of dermal filler is known as a stimulator.
This non-toxic and biodegradable substance has been used for more than 40 years as a suture material. There are many facial fillers available depending on your needs and how long you want the effects to last. According to the American Academy of Dermatology, side effects from facial fillers tend to go away within 7-14 days. Injectable dermal fillers can plump thin lips, improve shallow contours, smooth facial folds, reduce wrinkles, and improve scarring.
Botox contains botulinum toxin which paralyzes facial muscles to minimize wrinkle formation while dermal fillers add volume to the face to reduce wrinkles' appearance. Restylane-L, Juvederm, and Belotero are commonly used for facial wrinkles, asymmetry, and volume loss. They have also manufactured dermal fillers to address various facial issues such as smoothing wrinkles and adding volume to sunken or depressed areas. A Botox injection is similar to a dermal filler injection in that it aims to reduce facial lines and wrinkles but works differently. Dermal fillers are gel-like substances injected under the skin to restore lost volume, smooth lines and wrinkles, or improve facial contours.
These gel-like fillers are injected directly into soft tissues of the skin (usually facial areas) providing hydration and structural support where needed.
