A little goes a long way
The first thing I noticed was the scent, which I would think others would also find appealing. When I used it, I was happy to find that a little product went a long way. Although this is a liquid soap, it felt like a bar soap on my skin. For me, it did a great job at cleaning and deodorizing my skin.

Great Detox Body Wash
Been using this once a week for about a month and it works great. Skin feels detoxed after and stripped of the nasty oils but not over stripped like a lot of products out there. My skin remained soft and smooth after and felt truly cleaner and fresher. Like I mentioned I only use it once a week personally but I don't see where it would be a problem to use it more frequently if you want to. Its another great product from an already outstanding company !

Tree Tea Body Wash
It does its job of decreasing ringworm and body flake skin itch. I need to give more time to make it work. Patience is the key. It has strong scents of Tea Tree Oil. After rinsing them off for a couple of minutes, it gives a clean rubbery feeling to it. Make sure you moisturize your skin after the shower bath.

Stick caused breakout on face and neck
This is a wonderful product but be wary if needing it for face and neck. It immediately caused blocked pores where pores were smaller.
