Calm down Rita, you can go to the beach without anybody noticing anything! The subdermal implant is a discrete and personal. It is not noticeable to the naked eye, but the two ends of the implant can be felt if you press your fingers gently at the insertion point. Since it is radio-opaque, it can be viewed using an X-ray or a CT scan. It is also visible through ultrasound and magnetic resonance imaging.
