Well, I rubbed it on like lotion and it does stay on the skin (not soak in) but it didn't stain my clothes or sheets. It did make them smell though I guess it soaks in through the night cause but I didn't really pay attention. Just showered as usual. On my breast area, after the third day I noticed it started to kinda crust up. But I also kinda scrubbed with it there... so that might have been it. I was so terrified that I had really messed up my skin. After the irritation cleared up, so did the dark patches...
On my inside elbows, I stopped after three days and didn't really notice a difference. Then later that week at work, I looked at them and realized they were gone! That one I didn't "scrub in".
Those were my experiences.
