What is PLLA material

The origin of PLLA (Poly(L-Lactic Acid))

For many years, lactic acid polymers have been widely used in different types of medical fields, such as absorbable sutures, bone implants and soft tissue implants, and PLLA has been widely used in Europe to treat facial aging.

Different from cosmetic fillers such as hyaluronic acid, allogeneic collagen and autologous fat, PLLA (polyl-lactic acid) belongs to a new generation of medical regenerative materials.

What is PLLA material?

PLLA (polyl-lactic acid) is an important biodegradable polymer material, which is characterized by non-toxic, non-irritating, biodegradable absorption, high strength, good plasticity and easy processing.

The degradation period is 2~12 months. The degradation cycle can also be changed according to the addition of different modifiers. PLLA is decomposed by enzymes in the organism and eventually forms carbon dioxide and water, which has good biological compatibility.

The use of PLLA (poly-L-lactic acid)

First synthesized by French chemists in 1954, PLLA (polyl-lactic acid) has been used in the medical field for nearly 40 years, mainly for surgical sutures, dentistry, ophthalmology, pharmaceutical controlled release systems, partial fillers for bone and soft tissue defects, bioabsorbable scaffolds, etc.

In 1999, PLLA (poly-L-lactic acid) was introduced in Europe for soft tissue filling.

In 2004, PLLA (poly-L-lactic acid) was introduced to the U.S. market and was initially approved by the FDA to treat facial tissue atrophy in AIDS patients.

In 2009, the FDA approved PLLA (poly-L-lactic acid) for facial medical cosmetic use in the normal population.

Polyl-lactic acid (PLLA) is a regenerative material. By inducing human fibroblasts to secrete collagen, the new collagen fills up the volume of the original missing part and restores the skin elastic network, thus achieving anti-aging effect. In addition, the microspheres can be completely metabolized by the human body without residue, and there will be no sequelae such as “pasting”. Poly-l-lactic acid (PLLA) has been widely used in the medical field for nearly 40 years because of its safety, and after being applied in the field of medical cosmetics, it has successively obtained the permission of authoritative management agencies from many countries:

It is certified by the US Food and Drug Administration (FDA) as a cosmetic injection product, becoming one of the few biodegradable medical materials approved by the US Food and Drug Administration (FDA).


What is the use of PLLA?

PLLA has many uses, mainly used in surgical sutures, dentistry, ophthalmology, pharmaceutical controlled release systems, artificial skin, artificial blood vessels, bone and soft tissue defect partial fillers, bioabsorbable stents and other medical and pharmaceutical fields.

PLLA (poly-L-lactic acid) is also the main component of Tongyan needle, which can induce the synthesis of collagen fibers. Different from hyaluronic acid static fillers, it can increase tissue capacity and improve skin texture by inducing the synthesis of collagen fibers.

PLLA (poly-L-lactic acid) has good efficacy and safety, and is widely used in the medical field. From the effect point of view, through the dermis, subcutaneous injection, can stimulate collagen and elastic fiber proliferation, effectively improve facial relaxation, wrinkles and other problems.

Advantages of PLLA (poly-L-lactic acid)

PLLA raw material is derived from starch extracted from plants. After fermentation, it becomes lactic acid, and then polymerized into PLLA (poly-L-lactic acid) has relatively high safety, does not cause rejection in the body, and can be catabolized in the body. Its maintenance time is longer, generally can be maintained for 1 to 3 years, can be enhanced by injection to make the effect more lasting.

The market demand for poly-L-lactic acid (PLLA) is great

“Anti-aging” for young people, “anti-aging” for middle-aged people, “anti-aging” for the elderly, and “anti-aging” have long been the topic of the people. At present, the popular medical beauty projects focus on facial anti-aging, and gradually make anti-aging consumption daily and popular; Facing the huge market demand, poly-L-lactic acid (PLLA) materials can meet it; PLLA is a new type of recycled material with high safety and can be metabolically degraded by human body. Suitable for all ages, meet the anti-aging needs of consumers in many ways;

In addition, poly-L-lactic acid (PLLA) can be used for anti-aging in multiple facial locations, which can further meet the market demand, so it is highly recognized by practitioners and consumers.
