5ml Poly-L-Lactic Acid

• What is PLLA?

It is a biodegradable polymer, mainly composed of Poly- L-lactic acid monomers. It is widely used in medicine, cosmetics and other fields, especially in the field of medical beauty, where it has attracted attention as a material that promotes collagen proliferation and helps tissue regeneration.

• How does PLLA degrade?

PLLA (polylactic acid) is biodegradable. After use, it can be decomposed into water and CO2 under certain conditions. Water and CO2 are then transformed into plants such as corn through photosynthesis, thus forming an organic cycle.

• How long can poly-L-lactic acid collagen last?

The duration of poly-L-lactic acid collagen varies from person to person, but generally speaking, it can last for about 1-2 years.

Its duration is affected by many factors, such as the individual’s metabolic rate. People with faster metabolism may metabolize poly-L-lactic acid collagen faster, and the duration is relatively shorter; the injection site also has an impact, such as areas with greater mobility, such as areas with rich facial expressions, which may shorten the duration due to muscle movement; in addition, the injection dose and frequency are also related. Generally, multiple injections of appropriate amounts can extend the duration of the effect to a certain extent.

• Product Introduction：

Poly-L-lactic acid (PLLA) is a biodegradable synthetic polymer made from the polymerization of lactic acid. It can be decomposed into water and carbon dioxide in the body and has good biocompatibility.

Mechanism of action

After injection into the skin, it is not a filler itself, but stimulates fibroblasts, activates the body’s own repair mechanism, promotes the production of collagen, hyaluronic acid and elastin, and stimulates the proliferation and rearrangement of collagen to reduce facial wrinkles and fine lines, restore the skin to firmness and fullness, achieve filling and lifting effects, and achieve facial rejuvenation.

Main uses

• Medical beauty: facial anti-aging, improve nasolabial folds, tear grooves, cheek depressions, apple muscle loss and other aging problems; contour shaping, repair facial contours, such as sunken temples and unclear jaw lines; body shaping, used for incremental shaping of buttocks and other parts.

• Medical use: used for tissue repair and postoperative depression filling; as an implant material for orthopedics and dentistry.

Advantages

• Natural effect: The effect gradually appears, the transition is natural, and there will be no “stiffness”.

• Long-lasting: Stimulate collagen production, the effect can last for 18 months – 2 years or even longer.

• High safety: It can be completely metabolized, does not remain in the body, and the risk of side effects is low.

• Promote skin quality improvement: In addition to filling, it can also improve skin elasticity and radiance.

Treatment process

• Initial injection: The doctor mixes poly-L-lactic acid with saline and injects it into the deep layer of the skin. After the injection, the saline has an immediate filling feeling, and the “volume” will disappear as it is absorbed.

• Gradual effect: It takes 4-6 weeks to stimulate collagen proliferation, and the effect is significant and reaches its best after about 2-3 months.

• Injection course: Generally, 2-3 injections are required, with an interval of 4-6 weeks each time, depending on individual conditions.

Adverse reactions and precautions

Normal use is safe and reliable, but adverse reactions such as tissue inflammation, scar hyperplasia, infection and foreign body reaction may occur. After the treatment, the skin will be temporarily red and swollen. Ice compress within 24 hours can reduce swelling and bruising; the treated area needs circular massage for five consecutive days, five times a day, five minutes each time. It needs to be operated by a professional doctor and a regular medical institution should be selected. In addition, poly-L-lactic acid is the main active ingredient of “baby face needle”. Products with it as the main ingredient include Sculptra, AestheFill, Avilan, and Rubai Angel.
