The Medicube Age-R Booster Gel Serumgel is a lightweight gel that felt slightly sticky when I first applied on my skin. Once it was absorbed, my skin felt smooth. I used the gel with my facial massager and it felt refreshing on my face. It wasn't moisturizing or greasy. I've yet to see any results, however I will continue to use it.

I don’t have a Medicube micro current device so I tested with my Solawave red light wand and I think works great. I also have a radio frequency machine that im curious if works too but I have no idea if is the proper gel/conductor since the brand says is specific for micro current devices.

This is the booster gel used with the Medicube Age-R USSERA device, and I've been using it consistently for the last couple of months with good results, and the booster gel is to be used in conjunction with the USSERA. The USSERA is an ultrasonic collagen stimulating device and with this booster gel, can be used every other day, or 2-3 times a week, for purposes of firming the skin and reducing the appearance of fine lines. To this end it works very well, and after a couple of months of use, the results are noticeable.

I have been using this without a device for my face a few times a week in my routine. My face feels softer in the morning but no noticeable results yet. I plan to try out with a few devices I have though. I have a Dermawand and a Ihelol face wand I will use and come back with an update.

I like this gel serum because it's hard to find the perfect cream, lotion, or oil to use with facial massage tools! I love how it feels on the face with various tools, especially with my light therapy massage as well as the vibrating Guasha tool l. While I'm not entirely sure about its superiority in moisturizing and nourishment, it's definitely one of the best serums to be used with skincare devices, in my opinion. It also didn't irritate my skin during sensitive stages. For your information, I have oil-combination skin that can become sensitive depending on my menstrual cycle.

love this product and would recommend. feel great on the face and works great with rf machine.

I use this after using a Gua sha jade on my facial muscles. I like the feeling of how it makes my face smoother the next day.

I liked every thing about it but the price, so to make it last longer I spray water on my face while using the Medicube Derma EMS Shot

I use this gel with my nuface trinity and it works great I also use it with my radio frequency device.

So the stickiness is probably because I apply too much of the serum hah, but I found it does pill a little bit. But I love it anyway because it feels really nice, keeps my skin really moist, has no fragrance.
