Liztox Side Effects – What to Watch Out For

Jun 7, 2024

Botulinum toxins, a popular choice for cosmetic purposes, offer the allure of smoother skin and reduced wrinkles. But like any medical treatment, they come with potential side effects, emphasizing the need for a safer alternative.

Liztox is a botulinum toxin injection from South Korea that’s gaining popularity due to its effective wrinkle-smoothing and skin-tightening properties. Many individuals are drawn to its long-lasting effects, making it a top contender in non-invasive cosmetic procedures.

This article explores Liztox’s science and discusses potential side effects so patients and professionals can understand how to manage them effectively.

Key Takeaways

  • Liztox, like other botulinum toxin injections, can cause mild side effects such as redness, swelling, and bruising at the injection site. These reactions are typically temporary and resolve within a few days.
  • One potential side effect of Liztox is muscle weakness near the injection area. This can affect facial expressions and cause issues such as drooping eyelids or an uneven smile. These effects usually subside within a few weeks.
  • Although rare, some individuals may experience allergic reactions to Liztox, including itching, rash, or more severe symptoms like difficulty breathing. If these occur, immediate medical attention is necessary.
  • Some users report experiencing headaches, flu-like symptoms, or a general feeling of malaise after receiving Liztox injections. These symptoms are generally mild and temporary.
  • In rare cases, the toxin can spread beyond the injection site, leading to symptoms such as difficulty swallowing, speaking, or breathing. If these symptoms appear, it is crucial to seek medical help.

Common Side Effects of Liztox

Getting Liztox injections can cause some common side effects. People often feel pain, see swelling or redness, and might get bruises where they got the shot.

  • Localized Pain at Injection Site: A common but brief side effect of Liztox injections. Using precise techniques can reduce this discomfort. Patients comparing Liztox to Botox or Xeomin report similar sensations. Proper pre- and post-injection care is crucial for managing this side effect effectively.
  • Swelling and Redness: Usually occur after Liztox injections. This happens because the body reacts to the needle and the substance injected. These side effects often go away on their own in a few days. Keeping the area calm might help reduce swelling faster.
  • Bruising and Tenderness: These are often caused by the needle hitting a small blood vessel. The bruising typically fades within a few days, and the tenderness subsides quickly. Patients can be reassured that these effects are typical and usually resolve without extra care.

Rare but Serious Adverse Events

Liztox can occasionally cause significant health issues that are rare but can be extremely serious. It’s important to be aware of this potential risk.

  • Allergic Reactions: These are rare but important to know about. Signs of an allergic reaction include itching, rash, and trouble breathing. If a patient shows these signs after a Liztox injection, they need help fast.
  • Nerve Damage: Nerve damage can happen if the injection hits a nerve or if it spreads beyond the intended area. Nerve damage from Liztox injections may cause weakness or loss of sensation near the site, affecting facial movement or blinking. Following the Liztox dilution chart closely is vital to minimize this risk and ensure accurate placement and dosage for safe and effective treatments.
  • Muscle weakness: Muscle weakness can occur after Liztox injections, typically near the injection site but sometimes spreading. Doctors should monitor patients for difficulty swallowing, speaking, or breathing, which require prompt attention. Early discussion of muscle weakness signs between patients and doctors is crucial to prevent serious complications.

Clinical Data and Patient Case Studies

The ongoing phase III clinical trial evaluating the efficacy and safety of Liztox in subjects with benign masseteric hypertrophy. This study is a double-blind, randomized, placebo-controlled, multi-center trial. It aims to assess the change from baseline in masseter muscle thickness by ultrasonography. The trial started a year ago and is estimated to be completed by 2025.

If you’re considering using Liztox, it’s important to discuss it with your healthcare provider to understand the potential risks and benefits.

Comparison with Other Similar Treatments

Exploring how Liztox compares to other treatments provides clarity for medical professionals. This comparison focuses on efficacy, side effects, and applications. Liztox and Botox share a similar base in botulinum toxin type A and show similar side effects. Despite this, each boasts unique applications, with Liztox standing out for its minimal side effects in specific treatments.

Mitigating and Managing Side Effects

To handle side effects well, start with an intelligent choice of patients and a good look before treatment. This ensures that the treatment is safe and effective for each person.

  • Check medical history for allergies, neurological, or muscle diseases.
  • Discuss goals and expectations to ensure Liztox aligns with desired outcomes.
  • Evaluate skin for infections or issues that could affect injection sites.
  • Review medications, especially blood thinners, which can increase bruising.
  • Examine facial muscles to predict Liztox’s effectiveness on wrinkles.
  • Assess if Liztox is suitable for their condition, particularly mimic wrinkles.
  • Clearly explain possible side effects for informed decision-making.

Injection Techniques to Minimize Side Effects

After carefully selecting patients who are good candidates for Liztox, it’s crucial to focus on the actual injection process. The proper technique can significantly reduce side effects like pain, swelling, and bruising.

  • Choose the correct needle size to reduce bruising and discomfort.
  • Stick to precise locations to avoid significant side effects.
  • Control the injection depth for optimal results.
  • Apply gentle pressure after injection to prevent swelling.
  • Keep movements steady to minimize patient discomfort.
  • Space out injections to avoid swelling or uneven appearance.
  • Limit the amount used to prevent over-treatment and muscle weakness.
  • Cleanse the skin thoroughly to reduce infection risk.
  • Give clear post-care instructions to ensure proper care.
  • Introduce ice immediately after treatment to reduce swelling or redness.

Posttreatment Care and Monitoring

Mastering injection techniques and ensuring proper post-treatment care are essential. Immediately check the injection site for reactions such as swelling or redness. Advise applying cold compresses to reduce swelling and inform about expected recovery times. Schedule follow-up appointments to assess results and provide post-procedure activity restrictions, pain relief recommendations, skincare guidance, and the importance of sunscreen use.

Guidelines for Medical Professionals

Doctors need to spot and treat side effects quickly. They should also teach patients about possible risks before starting treatment.

  • Look for immediate reactions post-injection, such as pain, swelling, redness, or bruising at the injection site. These are common but should fade quickly.
  • Keep an eye out for signs of allergic reactions. Symptoms like itching, rash, or difficulty breathing require urgent care.
  • Notice any muscle weakness or drooping in areas not treated with Liztox; this could indicate the toxin has spread from the injection site.
  • Pay attention to patients reporting unusual symptoms after their procedure, such as headaches and respiratory issues, as indicated in some Liztox reviews.
  • Ask patients about changes in their vision or voice and signs suggesting nerve damage.
  • Monitor for excessive sweating or dry mouth symptoms, as these can indicate Liztox affecting areas beyond the targeted treatment zone.
  • Evaluate the injection technique if side effects persist.

Reporting and Managing Adverse Events

Reporting and managing adverse events following Liztox treatment is crucial for patient safety and maintaining treatment integrity. Steps include collecting detailed information about the side effects, reporting it according to health authority guidelines, and openly communicating with the patient. 

Medical intervention may be necessary, and regular follow-ups ensure proper recovery. All actions should be documented, and personal practices reviewed to prevent future occurrences. Continuous education about Liztox and its side effects is essential, as is sharing findings with peers to enhance broader understanding and prevention strategies.


Liztox has its own set of side effects, just like any treatment. Most people might see minor issues like pain or swelling in the injection area. A few might face big problems, such as allergic reactions. Knowing these risks helps doctors and patients make better choices. Everyone should discuss these possible effects before starting treatment. This way, patients can enjoy smoother skin without unwanted surprises.
