Thank you for your thoughtful question. It’s very understandable to be cautious, especially when you’ve had orthognathic (jaw) surgery with titanium screws or plates in the past. The short answer is that extra caution is recommended, and in many cases these types of at-home devices are not advised directly over areas containing metal implants. The Medicube AGE‑R Booster Pro is a facial device that uses several energy-based technologies, including microcurrent, electrical muscle stimulation (EMS), electroporation, and LED light to stimulate muscles, enhance skincare absorption, and improve skin firmness. While these technologies are generally safe for healthy skin, the manufacturer’s precautions note that the device should not be used in people with metal implants or pacemakers, and it should also be avoided on areas where surgery has been performed. Why metal implants can be a concern Even though titanium is very stable and commonly used in facial surgery, devices that deliver electrical currents or radiofrequency energy can sometimes interact with metal in the body. Potential issues include: • Localized heating of the metal implant • Altered electrical conduction around the implant • Increased nerve or tooth sensitivity in the jaw area These effects are not guaranteed to happen, but the reason many manufacturers list metal implants as a precaution is to avoid unpredictable energy conduction around surgical hardware. In your specific situation Because your surgery was 34 years ago, the bone has almost certainly healed completely and the titanium screws are well integrated. From a structural standpoint, that is reassuring. However, the device still delivers electrical stimulation to facial muscles, and the jaw area is very close to where orthognathic fixation screws are typically placed. For that reason, I would generally recommend: • Avoid using the device directly over the jawline or lower face where the screws are located • If used at all, limit it to upper face areas (forehead, temples, cheeks) • Start with the lowest intensity settings A practical dermatology perspective Many patients with old facial plates or screws can safely undergo treatments like lasers or microneedling, but electrical stimulation devices are a bit different because the current travels through tissues. For that reason, when there is any metal hardware in the jaw, I tend to recommend err on the side of caution and avoid direct use over that region. Bottom line Your titanium screws themselves are unlikely to move or be damaged, but because this device uses electrical stimulation technologies, it’s generally safest to avoid using it over areas containing metal implants, particularly the jawline. If you choose to use the device, keeping it away from the surgical hardware area would be the most conservative and safest approach.
