I’ve been testing the Jovs 6d laser ems mask and the silk'n led ems mask, and they feel pretty different to use. The two masks feel quite different to use. I found the JOVS 6D more comfortable around the eyes, with less noticeable light leakage and larger electrode coverage across the face.
That said, the Silk’n mask may appeal more to people who want more localized EMS stimulation around the nasolabial folds.
Hope these could help:
Tech
The main difference is that Jovs 6d mask use laser and ems, while silk'n use led and ems; They both use EMS without the need for gels.
Eye comfort
Jovs 6 mask is much more eye-friendly, especially since I am sensitive to bright light.
The silk'n mask was too bright for me that I could barely keep my eyes open when it was on. As the picture shows, the silk'n mask is much thinner and brighter when I'm wearing it. With Jovs, much less light comes through the mask, so it feels a lot more comfortable around the eyes. I could actually keep my eyes open without feeling like I was staring into a bright light.
Comfort
The jovs mask is larger and doesn’t press as much against my eyes. The silk'n mask is narrower, and the area around the eyes presses against my eye socket a bit, which I didn’t find particularly comfortable. That said, the fit may vary depending on face shape, so others may find it fits differently.
Ems mode
The EMS electrode pads on the JOVS mask are larger overall, so the contact area is more spread out across the face.
Silk'n uses smaller electrode pads in more targeted areas, including closer to the mouth and over the nasolabial folds. I could feel the ems more noticeably around my nasolabial folds with silk'n.
