Just wanted to give a quick update on my use. This is my third bar. The first two were from the older batches. I have noticed a slight darkening of the stretch marks. It's very subtle, but is very promising. I am unsure if others have reported this, but where I see the most change is with the heat rash on my arms. The redness seems to be fading quite a bit. I like how my tanning is coming in as well. The colour seems to be much deeper. Thanks for a very innovative product :box:
