Silicon body jewelry is a great substitute for acrylic jewelry. It comes from implant grade silicon. Silicon is the perfect material for individuals with metal allergies and/or sensitive skin. This type of material is known to be great for extreme sports and temperatures. It is easy to clean, soft and flexible. Silicone body piercings can be easily squashed to be inserted and will always regain its original shape. This type of material unlike metal will not push into your skin. Although silicone jewelry can be used for all piercings, it is not recommended in the use of stretching purposes.
