Products for facial fillers are mainly divided into hyaluronic acid, recycled materials and collagen.
hyaluronic acid filler
Hyaluronic acid is mainly gelatinous and granular.
The main component is hyaluronic acid.
The same component is the extracellular matrix of human tissue.
Principle of action: volume filling.
Scope of application: apple muscle, nasal base, law lines, mouth lines, chin, nose, etc.
Usually you can see the obvious effect after the injection. The course of the disease is generally 6-18 months.
Advantages: Wide range of adaptation, can be used for shaping, can also fill the depression, reversible effect, can use dissolved enzymes, high safety, less allergic rejection.
Disadvantages: Many kinds of products, need a variety of combinations.
In general, another injection is needed around 6-9 months to maintain the best results.
Recycled materials :70%CMC+30%PCL and PLLA
Recycled materials include girl's needle(like ellanse)and baby's needle（like Sculptra）
The main composition of the girl's needle is 70% biodegradable material (CMC) +30% microsphere polycaprolactone (PCL).
The type is a biodegradable polymer synthetic material。
Principle of action: CMC acts as a filling effect, and PCL stimulates its own collagen proliferation to achieve anti-aging and firming and enhancing effects。
Scope of adaptation: facial depression and wrinkle removal, not suitable for nose, chin, lips and other shallow parts。
Generally, the injection will have an effect, lasting about 1-2 years.
Advantages: Stimulate collagen regeneration, filling immediacy effect is obvious.
Disadvantages: The regeneration effect varies from person to person, the adaptation range is small, the effect is irreversible.
In general, another injection is needed around 6-12 months to maintain the best results.
The main component of baby's needle(Sculptra) is PLLA L-polylactic acid. It is also a biodegradable polymer synthetic material。
Principle of action: By stimulating your own collagen to increase to you, to achieve anti-aging and firming and enhancing effects
Scope of adaptation: facial depression and wrinkle removal, not suitable for nose, chin, lips and other parts.
After the injection is generally 4-6 weeks after the gradual effect, the best effect of 6 months, the duration of 2-3 years.
Advantages: Stimulate collagen regeneration, filling immediacy effect is obvious.
Disadvantages: The regeneration effect varies from person to person, the adaptation range is small, the effect is irreversible.
It should be noted that the single filling effect is limited, and multiple injections are required to fill, generally at a interval of 4-6 weeks.
3.collagen injectable
Collagen is mainly composed of xenocollagen derived from animals.
The type belongs to similar components of extracellular matrix of human tissue.
Principle of action: Volume filling, stimulate collagen.
Scope of application: Facial dermal tissue filling to correct frontal dynamic wrinkles (such as eyebrow lines, raised head lines, etc.), epidermal depressions, wrinkles, acne, etc.
The effect is usually immediate after injection, and the maintenance time is 6-9 months.
The advantage is that it is absorbed by the human body and can stimulate collagen regeneration in the body.
The disadvantage is that it is easy to cause rejection allergy, the effect is irreversible, the support is weak, and the shape is general.
In addition, it takes 2-3 months for another injection to be more effective.
