I tested 6 microcurrent devices for 2 months. This is the best for firm skin in 2026


Microcurrent Skin Gym Stick: Unfortunately, this device is not FDA approved, so I wouldn’t feel comfortable recommending it. If I bought it, I would be careful about its intensity and around the eyes, because it made spots appear across my vision briefly during use. The instructions for this device don’t say anything about using it on either side of the neck, so I avoided that area. They also require batteries and can’t be recharged, which I personally don’t find ideal. The device itself feels lighter and cheaper than the others, which makes sense, as it costs $99. As for the gel, like many others I tested, it did not last throughout the entire treatment period.

Medicube Age-R Booster Pro: Although I enjoyed using the device and think it has a great design, it is not FDA approved. This is likely because it is made in Korea, not the United States. It is designed to create a glass-skinned appearance. It has four modes, each with five levels of intensity: Booster (electro-perforation for glowing skin), MC (micro-current for intense contours), Derma Shot (electrical muscle stimulation to contour) and Air Shot (electro-needles to tighten pores). It also provides LED light therapy. I wish the device had more information about what specifically happens when you use each mode. Instead, I had to do my research to learn more so I could feel safe and confident using the device.

For microcurrent specifically, it says you don’t need a conductive gel and you can use regular skincare, but I haven’t found this to be the case. If I used a regular moisturizer, it wasn’t long lasting and wasn’t soft enough to treat. I started with the first level of intensity and worked my way up, but I found the sensation strong enough to warrant the use of a conductive gel, so I used my ZIIP product. I would be careful around eyes with high intensity.

The AGE-R app offers a tracking calendar, visual progress tracking, guided videos, and personalized device settings. However, the guided videos called “Shorts” looked more like social media videos, and I wish they were more structured and included specific audio instructions.

I liked the design of the device with its screen, and found it easy to hold and maneuver around the face. There is also audio that shows which mode you are using, the intensity of the treatment and how many minutes have passed during the treatment, which is a great feature for easy access. There’s no need for a stand since the device can stand upright on its own, and I like that the charger attaches to the top of the device so it can still stand on a work surface when charging.

A recent viral video on TikTok said that this device can cause Bell’s palsy, which is paralysis or weakness on one side of the face due to nerve damage. Medicube He respondedHe called the claim “misleading” and stated that the device’s electrical stimulation cannot cause nerve damage because it operates at a low output between 7 mA and 14 mA, which is lower than other devices and cannot cause nerve damage or paralysis.
