Poly-L-lactic acid is an innovative bioabsorbable polymer material. In recent years, it has become a "new choice for anti-age" that has attracted much attention in the field of medical beauty. It is not a filler in the traditional sense, but after subcutaneous injection, its tiny particles can be gradually absorbed by the body and at the same time stimulate the body to produce new collagen, thereby achieving the effects of filling, smoothing wrinkles, and improving skin tightness. Its core advantages are good biocompatibility, high safety, and long-lasting effects. It can fundamentally improve skin quality and achieve natural and healthy rejuvenation. Although there may be temporary reactions such as slight redness and induration after injection, the overall recovery period is short, making it an ideal choice for people who pursue natural beauty to remove wrinkles.

As a new type of medical beauty filler, poly (L-lactic acid) has attracted much attention in the field of anti-aging in recent years. It can not only effectively improve skin slack, fine lines and other problems, but also has good biocompatibility and reversibility. poly (L-lactic acid) What is it? What are its advantages and considerations? This article will provide you with a detailed analysis.

The core principle of poly-L-lactic acid

Poly (L-lactic acid) is a high-purity L-lactic acid, which is an absorbable filler. It stimulates the body's own collagen regeneration to achieve filling, shaping and repair effects. It is in line with traditional玻尿酸、肉毒素Unlike fillers, poly-L-lactic acid does not form permanent filling in the body. Instead, it is gradually absorbed by the body and stimulates the production of collagen to achieve natural repair of the skin.

The molecular structure of poly-L-lactic acid can be gradually decomposed and absorbed by the human body. At the same time, during the decomposition process, it continuously stimulates surrounding tissues to produce new collagen fibers. This process of "awakening" collagen cells makes the skin gradually regain elasticity, and fine lines and wrinkles also fade away.

Indications for poly-L-lactic acid

1. Facial wrinkle filling: Poly-L-lactic acid is particularly suitable for filling static wrinkles, such as forehead lines, eyebrow lines, nasolabial folds, etc. It can stimulatecollagen regeneration, to restore skin fullness and elasticity.

2. Facial contouring: For problems such as unclear facial contours and loose skin, poly-L-lactic acid can fill depressed areas on the face to improve the three-dimensional effect of the face.

3. 改善肤质: Poly-L-lactic acid can not only improve wrinkles, but also promote the renewal of skin cells and make the skin smoother and more delicate.

4. 唇部塑形: For people with thin lips and obvious lip lines, poly-L-lactic acid can fill the lips to make the lips fuller and more natural.

Advantages of poly-L-lactic acid

1. 安全性高: Poly-L-lactic acid is derived from natural lactic acid. It is highly purified, has good biocompatibility and is not easy to cause allergic reactions.

2. 效果自然: Because poly-L-lactic acid achieves its effect by stimulating the regeneration of its own collagen, the postoperative effect is more natural and there will be no "false feeling".

3. 可逆性强: If you are not satisfied with the effect, poly-L-lactic acid can be dissolved by injecting hyaluronase, and the effect is reversible.

4. long-term effectiveness: Although poly-L-lactic acid is gradually absorbed by the body, during this process, new collagen will be continuously produced, and the effect can last for 1-2 years or more.

5. rapid postoperative recovery: After injection of poly-L-lactic acid, the recovery period is short, and daily makeup and work can usually be restored within a few days.

Precautions for poly-L-lactic acid

1. 术前评估: Before injecting poly-L-lactic acid, a facial evaluation needs to be performed by a professional doctor to determine the appropriate injection site and dose.

2. 术后护理: After injection, avoid pressing the injection site, keep your face clean, and avoid strenuous exercise and high temperature environments (such as sauna, steaming face, etc.).

3. 个体差异: Each person's skin condition and metabolic speed are different, and the appearance and duration of the effect will also vary.

4. Taboo population: Poly-L-lactic acid injection is not suitable for people allergic to poly-L-lactic acid or lactic acid products, pregnant women, nursing women, patients with infectious diseases, etc.

Common side effects of poly-L-lactic acid

1. Red and swollen, bruise: Slight redness or bruises may appear locally after injection, which usually resolves spontaneously within a few days.

2. nodules: In rare cases, poly-L-lactic acid may form induration at the injection site, but this condition usually gradually softens and absorbs over a few months.

3. asymmetric: If the injection technique is improper, facial asymmetry may occur, so it is important to choose an experienced doctor.

Differences between poly-L-lactic acid and other fillers

1. Differences with hyaluronic acid: Hyaluronic acid is a filled product with immediate effects but irreversible effects; while poly-L-lactic acid is a regenerative product with gradual effects but reversible effects.

2. The difference from Botox: Botox is mainly used for the improvement of dynamic wrinkles, while poly-L-lactic acid is mainly used for static wrinkles and skin regeneration.

3. Differences with collagen: Collagen fillers have a faster effect, but have a shorter duration; poly-L-lactic acid stimulates the regeneration of its own collagen, and the effect is more lasting.

Future development trend of poly-L-lactic acid

With the continuous development of medical beauty technology, the application range of poly-L-lactic acid is also expanding. poly-L-lactic acid may be combined with other ingredients (such as growth factors,透明质酸etc.) to form a more efficient composite preparation, further improving its cosmetic effect.

The application of poly-L-lactic acid in tissue repair, skin regeneration and other fields is also being actively explored, and is expected to play a role in more medical beauty scenarios in the future.

As a new type of medical beauty filler, poly-L-lactic acid has become the first choice for more and more beauty seekers due to its safety, natural effects and reversibility. Whether it is facial wrinkle filling or skin regeneration and repair, poly-L-lactic acid can bring satisfactory results. Any medical beauty project needs to be carried out under the guidance of a professional doctor to ensure safety and maximum effect.
