Our Silicone Patches are 100% Medical Grade Silicone certified which is known as being a hypoallergenic material. However, we do not recommend our Silicone Patches if you have a known allergy to silicone. Our other products are more than suitable for sensitive skin such as our our InfuseFAST Sheet Mask range which is free of parabens, dyes and fragrance. However, we do not recommend using them if you have any known allergies to any of the ingredients in the products.
