Useful if: you want the large PDRN gel intended to give a smooth glide with a face roller, gua sha or beauty device rather than a small treatment serum.
The current PDRN Booster Gel comes in a large 300ml pink tube. Medicube describes it as a facial gel for face rollers, gua sha and Booster Pro use.
Medicube also sells an older AGE-R Booster Gel Serum, so checking the full PDRN Booster Gel name and 300ml size helps avoid buying a different device gel.
The current formula is built around salmon DNA PDRN, seven peptides and niacinamide in a lightweight hydrating gel base. Medicube positions it for glide with skincare devices and also says it can be used on its own as a hydrating gel.
If a particular ingredient matters to you, check the live packaging before buying because cosmetic formulas can change by market or batch.
No. Medicube says the gel can also be used without a device as a normal hydrating step. If you are buying it specifically for an AGE-R device, follow the instructions for your exact model rather than assuming every device needs conductive gel.
