# LSR Silicone Key For Facial Cleanser
---
LSR Silicone Key For Facial Cleanser is a precision-molded liquid silicone rubber component designed exclusively for power/control buttons on electric facial cleansing devices. Manufactured by 橡楚（湖北）橡胶有限公司 at our facility in湖北省鄂州市鄂城区经济开发区凡口街道内河巷54号, this component combines the biocompatibility of medical-grade liquid silicone rubber with precise dimensional control to deliver reliable tactile feedback and long-term performance in daily skincare use.
As a specialized LSR product, this silicone key is formulated to resist repeated contact with facial cleansers, water, and skin care serums, maintaining its elasticity and tactile feel even after thousands of actuation cycles. Unlike general-purpose rubber buttons, our LSR silicone keys are engineered to meet the specific hygiene and durability requirements of personal skincare devices, balancing soft touch feedback with consistent actuation force to enhance the user experience of facial cleansers.
Our core production advantage lies in integrated liquid silicone injection molding, which allows us to produce net-shape silicone keys with complex geometries, custom textures, and consistent material properties without secondary processing. Each batch is produced under controlled manufacturing conditions aligned with our quality management system, ensuring consistent performance across all production runs.

Our LSR silicone keys use food-contact grade raw silicone material, free of BPA, phthalates, and other harmful additives that may irritate facial skin. The non-porous surface of LSR resists bacterial growth, even in the high-moisture bathroom environment where facial cleansers are commonly used. The surface does not trap residue from cleansers or skincare products, making it easy to clean and maintain hygiene during long-term use.
Unlike thermoplastic elastomer (TPE) buttons that can degrade or become greasy over time with repeated exposure to water and surfactants, our LSR silicone keys resist chemical attack from common facial cleanser ingredients, fragrances, and mild skincare acids. The material maintains consistent elasticity and actuation force for over 100,000 actuation cycles, eliminating the common problem of key sagging or loss of tactile feel that plagues lower-quality alternative materials.
Our precision LSR injection molding process achieves tight dimensional tolerances to ensure a seamless fit with your facial cleanser housing. We can customize the contour of the key top to match your device's design language, add non-slip textures for better finger grip during wet use, and adjust the internal rib structure to fine-tune actuation force to your product requirements. This level of customization ensures the silicone key integrates seamlessly with your finished device, improving overall product aesthetics and user experience.
The adjustable hardness range of our LSR formulation allows us to match the exact tactile feel your product design requires: from soft, cushioned key press feedback for premium devices to firmer actuation for entry-level models. The material's consistent compression set performance ensures that the tactile feel remains consistent throughout the lifespan of the facial cleanser, so users experience the same comfortable key press from the first use to the last.

LSR Silicone Key For Facial Cleanser is designed as a core functional component for all types of electric facial cleansing devices, including:
Beyond facial cleanser buttons, this LSR formulation is also suitable for other small control components in personal care devices, including electric toothbrush buttons, skincare device function selectors, and body cleansing device controls, where skin safety and wet environment durability are required.
For facial cleanser applications, the silicone key acts as both a control actuator and a water barrier: when properly assembled into the device housing, the elastic nature of LSR creates a continuous water-tight seal that prevents moisture from seeping into the internal electronic components, extending the overall lifespan of the finished facial cleanser.

We recommend the following hardness ranges based on common facial cleanser design requirements:
Our technical team can assist you in selecting the optimal hardness based on your key size and expected actuation force requirements.
We produce custom-sized LSR silicone keys based on your device's dimensional requirements. Common standard dimensions for circular facial cleanser keys range from 8mm to 20mm in diameter, with a typical thickness of 1.5mm to 3mm. We support custom non-circular shapes (oval, rectangular, contoured) to match your product design, and can add alignment features, mounting posts, or sealing lips as required by your assembly design.
We offer two standard material grades for facial cleanser silicone keys:
