Using System JO All - Over Body Luxury Shaving Gel is a breeze. First, make sure your skin is moist or wet, like after a short shower. Then, take an appropriate amount of the gel and apply it evenly to the area you want to shave. Rub it gently to create a nice lather. When you start shaving, you'll notice how smoothly the razor glides over your skin. For best results, use a sharp razor. As for precautions, although the gel is gentle, if you have extremely sensitive skin, it's a good idea to do a patch test on a small area first. Also, keep the gel out of reach of children. After use, store it in a cool, dry place. There's no special maintenance needed, just keep the bottle tightly closed to keep the gel fresh and effective.
