Lenisna Import: Doctor Explains Superior Effects Over Sculptra, Compared to Juvelook | TASAKI PHAMA

What is Lenisna? Differences from Sculptra

Lenisna is an injectable treatment using Poly-L-Lactic Acid (PLLA) that has been gaining attention in recent years. Similar to Sculptra, a conventional PLLA product, Lenisna stimulates fibroblasts and promotes collagen production, which is expected to improve skin firmness and elasticity. Lenisna is characterized by its combination of PLLA particles with Hyaluronic Acid (HA), providing both immediate and long-lasting effects.

Sculptra consists of PLLA alone and gradually exerts its effect by promoting collagen production after injection. On the other hand, Lenisna provides an immediate volumizing effect due to the Hyaluronic Acid, in addition to the collagen production promoting effect of PLLA. This makes it easier to feel the effects immediately after the treatment and covers the period until the effects of PLLA appear.

PLLA (Poly-L-Lactic Acid) is a biocompatible synthetic polymer that is gradually broken down in the body. In the medical field, it is used in various applications such as surgical sutures and fracture fixation materials. When PLLA is injected into the subcutaneous tissue, it triggers a foreign body reaction and activates fibroblasts. The activated fibroblasts produce extracellular matrix such as collagen, elastin, and hyaluronic acid, and reconstruct the structure of the skin. Through this process, skin firmness, elasticity, and volume are improved, and a youthful appearance can be restored.

Lenisna Ingredients and Features

• PLLA (Poly-L-Lactic Acid): Promotes collagen production
• Hyaluronic Acid (HA): Immediate volumizing and moisturizing

Sculptra Ingredients and Features

• PLLA (Poly-L-Lactic Acid): Gradually promotes collagen production

Lenisna vs. Juvelook: Comparison of Ingredients, Effects, and Duration

Lenisna and Juvelook are both injectable treatments that promote collagen production, but there are differences in the main ingredients and how the effects appear. The main components of Lenisna are PLLA and Hyaluronic Acid, while Juvelook consists of Polydextrose-L-Lactic Acid (PDLLA) and Hyaluronic Acid. PDLLA is an isomer of PLLA, and the decomposition rate and collagen production pattern are different.

Juvelook is characterized by PDLLA particles being smaller than PLLA and easier to disperse evenly. This is said to provide a more natural volumizing effect. In addition, Juvelook has a faster decomposition rate than PLLA, so the duration of the effect tends to be shorter than Lenisna.

When comparing the effects on nasolabial folds, Lenisna has an immediate effect due to Hyaluronic Acid, so some improvement can be expected immediately after the procedure. On the other hand, Juvelook gradually promotes collagen production, so it takes time for the effect to appear, but a natural finish can be expected.

Ingredient Differences

• Lenisna: PLLA (Poly-L-Lactic Acid) + Hyaluronic Acid
• Juvelook: PDLLA (Poly-L-Lactic Acid) + Hyaluronic Acid

Differences in Effects and Duration

• Lenisna: Balances immediate and long-lasting effects (immediate effect due to Hyaluronic Acid + long-term collagen production due to PLLA)
• Juvelook: Natural volumizing effect, duration tends to be shorter than Lenisna

Risks and Precautions of Lenisna Treatment

Lenisna treatment is generally considered safe, but there are risks associated with injections. The main risks include swelling, redness, pain, and bruising at the injection site. These symptoms usually improve spontaneously within a few days to a week.

Rarely, allergic reactions or infections may occur. Allergic reactions can be caused by hypersensitivity to PLLA or Hyaluronic Acid. Infections can be caused by treatment in unsanitary conditions or improper care after treatment.

When receiving Lenisna treatment, it is important to consult a doctor and fully inform them of your skin condition and allergy history. Also, regarding post-treatment care, it is important to follow the doctor’s instructions and take appropriate moisturizing and UV protection measures. If any abnormal symptoms appear after treatment, consult a doctor immediately.

Some PLLA-based treatments are approved by public institutions such as the FDA (U.S. Food and Drug Administration) and EMA (European Medicines Agency), but Lenisna may not be approved by these institutions. When receiving treatment, it is important to check with your doctor and make a decision based on sufficient information.

Possible Risks

• Swelling, redness, pain, and bruising at the injection site
• Allergic reaction
• Infection

Precautions

• Consult a doctor and inform them of your skin condition and allergy history
• Provide appropriate post-treatment care (moisturizing, UV protection)
• Consult a doctor immediately if any abnormal symptoms appear

Conclusion: Potential of Lenisna for Skin Rejuvenation

Lenisna is a new injectable treatment that combines PLLA and Hyaluronic Acid, and is expected as an option for skin rejuvenation treatment that balances immediate and long-lasting effects. Compared to conventional PLLA products such as Sculptra and Juvelook, it has the potential to provide more effective treatment.

However, Lenisna treatment also has risks associated with injections. When receiving treatment, it is important to consult a doctor and make a decision based on sufficient information. Also, regarding post-treatment care, it is important to follow the doctor’s instructions and perform appropriate management.

In the field of aesthetic medicine, new technologies and products are being developed every day. Lenisna is one of them, and it is expected that it will be established as a more effective and safe treatment method through future research and accumulation of clinical experience. Our company, Tasaki Pharmaceutical, will contribute to the development of aesthetic medicine by providing high-quality pharmaceuticals and medical devices to medical institutions.
