Do I need a Foreo device to use this serum?

No, but that is what it is designed for. It hydrates on its own; the conductivity benefit only matters with a microcurrent device.

Can I use it morning and night?

Yes. It is formulated for both daytime and nighttime use, and it layers well under sunscreen or moisturizer.

It is fragrance-free and built around ceramides and squalane, which suit sensitive skin. Patch test first if you react easily.

The 2.0 adds ceramides and electrolytes for barrier support and conductivity. The core hyaluronic acid and squalane base is similar.

A 30 ml pump bottle. The formula includes hyaluronic acid, squalane, ceramides, electrolytes, collagen, antioxidants and vitamin E.

On its own it mainly hydrates and plumps, which softens the look of fine lines. Firmer results come from pairing it with a microcurrent device.
