These soaps are large, 4.5 oz, but should be handled with care. If left in the shower, they will melt down pretty quickly, so try to store away from direct water. The best way to use, is to make a thick and creamy lather on the skin. This is perfect for face or body so get creative! I personally use this on my face and any places of tension, letting myself relax in the shower for up to ten minutes before rinsing off. Immediately, you will feel relaxed and more serene. **For pain, I like to hold it onto the area and rub it in with a little force- they’re made to be sturdy for this reason and then massage the area until the muscle relaxes **For all over relaxation. I massage it into my skin and let it sit for about 10 minutes, I make sure to leave it on my face as well to ensure it gets absorbed efficiently.
