Chemical and Biological Analysis of Aesthetic Fillers

Aesthetic fillers are substances that are used in nasolabial lines, mustache lines, smile lines, skin deformations and similar situations and are injected under the skin. Aesthetic dermal fillers correct lines and wrinkles by plumping these areas. Lip augmentation is also done with dermal fillers.

Hyaluronic acid is a substance that occurs naturally in the human body. Hyaluronic acid is generally used in the treatment of detached retinas and other eye injuries. It is injected into the eye during the procedure to help replace natural fluids. Hyaluronic acid filler is also used as lip filler in plastic surgery. Sometimes hyaluronic acid filler is applied to the skin to heal wounds, burns, skin ulcers and as a moisturizer.

There is increasing interest in the use of hyaluronic acid fillers to prevent the effects of aging. In fact, hyaluronic acid is promoted as the fountain of youth. However, there is no evidence to support the claim that taking it orally or applying it to the skin prevents changes due to aging. Hyaluronic acid filler acts as a cushion and lubricant in joints and other tissues. It can also affect the way the body responds to injuries.

The main areas where aesthetic dermal filler is applied are:

• bags under the eyes
• Forehead
• eyebrow lift
• Wrinkles around the eyes (crow's feet)
• Lines between the eyebrows
• Nasal lines (nasolabial lines)
• smile lines
• Mustache lines (vertical lines on the lips)
• lip plumping
• Lips
• asymmetrical lips
• Acne scars and skin deformations due to injuries
• Plumping of cheeks and cheekbones
• Correction of jaw structure
• Correction of asymmetries in any part of the body

Safe and FDA-approved aesthetic fillers include hyaluronic acid, polymethyl methacrylate, poly-L-lactic acid, calcium hydroxylapatite or one's own body fat. In general, the most appropriate one is chosen according to the person's skin type, age and other factors, as well as taking into account the effect the person wants to achieve:

• Hyaluronic acid. Hyaluronic acid is a natural component of the skin's connective tissue. Its safety and effectiveness have made this chemical the most common filler used in cosmetic facial procedures. Hyaluronic acid injections can smooth fine lines and wrinkles and add plumpness to the skin. The difference between hyaluronic acid products is in the size of the particles, which are designed to address different wrinkle depths. Smaller particles are applied for fine lines and larger particles for deeper wrinkles and folds.
• Calcium hydroxylapatite. This chemical treats deeper wrinkles and skin folds. This ingredient can help shape the jawline and restore volume in and around the cheeks. The effects of these injections last for up to three years when used to fill wrinkles and up to one year when used for shaping purposes.
• Polymethyl methacrylate. This filler consists of microspheres suspended in a collagen-based gel. The gel provides volume that lifts the skin to smooth wrinkles and acne scars. Microspheres stay in place and provide structural support for smoother-looking skin.
• Poly-L-lactic acid. This treatment, which was previously developed to treat severe facial wasting due to HIV infection, is now also used to eliminate facial aging. Injections last up to two years.
• Human fat. Fat collected from the person's own body is re-injected to increase facial fullness, fill deep wrinkles and create shallow lines. Using fat injections is somewhat more complicated than other injectable fillers as it requires liposuction to remove the fat before injection.
