Our verdict
The naming makes these look interchangeable, but they do different jobs. The Booster Gel Serum is a conductive booster gel, the slippery layer you apply so an Age-R device can glide and conduct. The Glutathione Glow Serum is a straightforward serum you can use with or without hardware. The ratings back the serum: 4.6 out of 5 from 781 reviews against 4.2 from 512, a gap wide enough to matter given both have real volume behind them. They also point at different things. Collagen and a firmness lean in the gel, glutathione and a brightening lean in the serum, and only the serum lists sensitive skin among its suitable types. If you already own an Age-R device and want the slip layer, the gel is the correct purchase and 4.3 is still respectable. Everyone else should buy the glutathione serum, which is both the better standalone product and the better reviewed one.
