TPE vs Silicone Materials in Aesthetic Injection Mannequins: Pros and Cons

Overview

Medarchitect’s aesthetic medical training models are primarily made using two types of materials: food-grade silicone and TPE (thermoplastic elastomer). Each material offers distinct characteristics in terms of texture, needle resistance, durability, and training realism. Understanding the differences between these two materials can help educators and trainees choose the most appropriate mannequin for different aesthetic injection training needs.

Pros and Cons of TPE Aesthetic Training Models

What is TPE Material?

TPE stands for Thermoplastic Elastomer, a type of polymer that combines the processability of plastic with the elasticity of rubber. At room temperature, it is soft and flexible, yet it can be molded like plastic. Because of these properties, TPE is widely used in medical training models, simulated skin, and other touch-and-feel educational products.

In the field of aesthetic injection training, TPE is a popular choice for making facial injection practice models due to its soft, elastic feel, good rebound, and strong moldability.

Why Use TPE for Facial Injection Training Models?

• Helps build basic injection skills: TPE is soft and elastic, with gentle resistance when inserting a needle. This makes it ideal for beginners to practice angles, depth, and basic techniques, gradually developing a stable injection feel.

• Supports high-frequency, repeated practice: TPE has good self-sealing properties, allowing it to withstand multiple injections without noticeable damage. This makes it perfect for classrooms and training institutions with intensive use.

• Allows clear visualization of internal anatomy: TPE can be made transparent or semi-transparent, so learners can see facial blood vessels, nerves, and injection layers, helping them understand anatomy and injection placement more intuitively.

• Cost-effective for large-scale training: Compared to silicone, TPE is cost-effective to produce and process, making it suitable for schools and training centers that need multiple models for teaching purposes.

• Supports liquid injection practice: TPE’s stable structure allows the use of simulated liquids for practicing injection paths and basic techniques, giving learners a more hands-on understanding of injection procedures.

Limitations of TPE Material

Although TPE models are soft and practical for facial injection training, they still have some limitations in simulating the resistance and layered feel of real human skin. Compared to actual skin, TPE generally provides lighter resistance, with less distinction between the epidermis, dermis, and subcutaneous layers. As a result, the realism is somewhat limited for high-precision or pre-clinical injection training.

In addition, compared to silicone, TPE surfaces may gradually show visible needle marks after repeated injections in the same area, which can affect the model’s appearance. TPE is also more sensitive to storage conditions, and prolonged storage may cause color changes, such as gradual yellowing.

Cleaning and Maintenance Guide for TPE Models

Gently clean them with warm water and mild soap. Avoid using alcohol or harsh solvents. After cleaning, let the model air dry or wipe it with a soft cloth. Store it away from high temperatures, direct sunlight, and heavy pressure. Regularly check the needle holes for recovery to help extend the model’s usable life.

Pros and Cons of Silicone Aesthetic Training Mannequin

What is Silicone Material?

Silicone is a type of polymer widely used in medical simulation and medical devices, known for its stability and realistic performance. The food-grade silicone used by Medarchitect offers reliable safety, resistance to aging, and realistic touch, closely mimicking the resistance and feedback of human skin during injections.

Because its physical properties are closer to real human tissue, silicone is often used to make facial injection training models that require a higher level of realism.

Why Use Silicone for Facial Injection Training Models?

Silicone offers clear advantages in simulating real skin structure and injection feedback. Compared to TPE, silicone provides resistance that is closer to real human tissue, helping learners practice injection depth, angle, and overall control. This makes silicone facial models more suitable for advanced training and pre-clinical practice.

In addition, silicone closely mimics the look and feel of real skin, reproducing the texture and shape of the human face more realistically. Its high stability, heat resistance, and durability allow it to maintain consistent touch and performance over time, making it ideal for training scenarios where realism and quality are highly important.

Limitations of Silicone Material

Although silicone provides a more realistic feel for facial injection training, it is generally more expensive than TPE due to higher material and manufacturing costs. In high-temperature environments or with frequent long-term use, the surface of silicone models may develop slight oiling, requiring proper cleaning and maintenance.

In addition, unlike transparent or semi-transparent TPE models, silicone facial models are usually made in lifelike skin tones and cannot easily be made transparent. This limits the ability to visually demonstrate internal blood vessels and nerves. Due to the nature of the material, silicone models are generally not recommended for liquid injection practice, as fluids may leak from needle holes. They are best used for practicing touch and injection feedback.

Cleaning and Maintenance Guide for Silicone Models

Silicone models are highly stable but still require proper care. Clean the surface with warm water and mild detergent, and store them away from high temperatures and humid environments to prevent slight oiling or color changes. Before practice, you can lightly dust the surface with baby powder to reduce stickiness and improve handling. Silicone models are not recommended for liquid injection, which helps maintain consistent feel and appearance over time.

Performance Comparison Chart

If your main needs are basic injection practice, anatomy demonstration, or liquid injection exercises, a TPE facial injection training model is likely the better choice.

If your goal is to simulate realistic skin feel, practice injection depth control, improve clinical realism, or have a model that closely resembles the appearance and skin tone of a real face, then a silicone facial injection training model is more suitable.

Ultimately, the choice of material depends on your training needs and usage scenarios, and there is no absolute standard. If you are unsure which model is right for you, feel free to contact us for guidance. We can provide professional advice based on your requirements to help you make the best choice.
