Allergic reactions to Embrace

We built Embrace with the highest quality materials to ensure that it passes all the FDA-required tests (specified in ISO 10993) for biocompatibility. It is, therefore, very unlikely that you'll develop an allergic reaction from Embrace.


However, some people may still notice a slight reaction on their skin. If this happens, please contact our support team ( with a photo of the affected area.

Important notes

If at any time the skin becomes red, itchy or if any pain is felt, we advise that you suspend or discontinue use and consult your doctor.

Without regular cleaning, skin irritation is more likely to occur, so please make sure to clean Embrace regularly.
