The One-device is compact and designed for smaller areas. It provides a quick 2-minute application when held about 10–15 cm from your face, allowing for 3–6 layers. This makes it ideal for use on the face, neck, and other smaller areas.

The Pro-device, on the other hand, is larger and equipped with a stronger spray, enabling a full application in just 15 seconds. Used approximately 30 cm from your face or body, it allows for 1–3 layers and is perfectly suited for tanning the entire body.
