Lifecasting is more than just art—it’s a deeply personal and precise process that captures the human form in remarkable detail. Whether you're a makeup artist, materials specialist, or a curious beginner, understanding how to work with Double Silicone Rubber is essential for creating professional-grade molds that reflect the finest skin textures and expressions.
At ArtMolds.com, we’re passionate about providing both the tools and the knowledge to help you succeed. In this guide, we’ll walk you through the complete process of life casting, sharing essential techniques, safety protocols, and expert insights to ensure a successful and safe experience—for both the artist and the model.
Life casting is the art of creating accurate three-dimensional replicas of the human body using mold-making materials. This technique has wide applications in film, theater, fine arts, and prosthetics. The star of this process is Double Silicone Rubber—a skin-safe, fast-curing material that captures even the smallest pores and creases with amazing clarity.
Before applying any material, ensure that the model is fully informed and comfortable. The environment should be quiet, private, and kept at a moderate room temperature. Always check for skin sensitivities or allergies by conducting a patch test with a small amount of silicone in advance. Keep emergency supplies handy and maintain open communication throughout the session. The model should never feel hesitant to speak up if something feels off.
Thoroughly clean the area of skin that will be cast. Remove all oils, lotions, or cosmetics. Apply a high-quality release agent—especially around areas with body hair like eyebrows or facial hair. This prevents discomfort and allows for easy demolding without damaging the model’s skin or the final cast.
Precise mixing is the key to success. Follow the manufacturer’s guidelines for ratio and timing. Stir gently to minimize air bubbles, which could impact the final texture. Once ready, begin applying the Double Silicone Rubber with a brush or spatula in thin, even layers. Start from the center and work outward to ensure smooth coverage. The silicone sets quickly, so apply efficiently but without rushing.
These delicate zones require extra care.
Holding still is critical, especially for facial or full-head casts. Discuss the pose ahead of time and rehearse if needed. Choose a position that the model can maintain comfortably for 20–40 minutes. Pillows, armrests, or standing aids can offer support.
Once the first layer cures, apply a second coat of silicone to build thickness and strength. Techniques like stippling or building small ridges can help secure the outer shell. Use tools such as tongue depressors to refine and smooth the form. This layer captures deeper detail and ensures your mold holds its shape.
To reinforce the silicone mold, apply a rigid support shell made of plastic bandages. Wet them slightly and layer over the silicone surface, overlapping each strip for added stability. Once the shell hardens, you’re ready to demold.
To remove the shell, gently break the vacuum seal at one edge and work around the mold without rushing. This prevents distortion or damage. Use soft tools to assist if needed, being mindful not to scratch the cast.
If casting a full head, applying a bald cap helps streamline the shape and reduce air pockets. Slick back hair with water or gel, apply the cap using skin-safe adhesive, and blend edges with powder or special FX makeup tools for a seamless fit.
In more complex molds, a cutting shim can be used to create seam lines and aid in demolding. Precision is essential to ensure the parts align perfectly later. Materials like smooth plastic or acetate sheets work well for this.
After the mold is fully cured and demolded, take time to examine your life cast. The final result should display flawless skin texture and accurate proportions. Minor imperfections can be touched up using additional silicone or clay.

1. What is the best material to use for life casting sensitive areas like the face?
For sensitive areas such as the face, Double Silicone Rubber is highly recommended. It’s skin-safe, flexible, and captures fine details like pores and wrinkles without causing irritation when used with a proper release agent.
2. How do I make sure the model is safe and comfortable during the lifecasting process?
Always conduct a patch test to check for allergies, maintain a comfortable room temperature, and keep communication open. Provide support for poses and never block the model’s airways—especially when casting around the nose and mouth.
3. Can I life cast someone with facial hair or eyebrows?
Yes, but extra preparation is required. Apply a generous layer of release agent like petroleum jelly to facial hair or eyebrows before applying the silicone. This ensures safe removal and prevents hair from pulling or sticking.
4. How many layers of silicone should I apply during lifecasting?
Typically, two layers are recommended. The first layer captures surface detail, while the second layer adds strength and structure to the mold. Techniques like stippling during the second layer can enhance the mold’s accuracy and durability.
5. What is a support shell, and why do I need it?
A support shell is a rigid outer casing made from materials like plastic bandages. It surrounds the silicone mold and maintains its shape during demolding. Without it, the silicone mold could flex, collapse, or deform, compromising the final cast.
