I didn't have enough patience to use this. I used it for 2 months and seen no results.
I used this religiously with high hopes and it did nothing for me.
The smell is pretty intense, but not enough to stop using it. I hardly use it now, but it did fade a small scar (by a little) I had.
This product has the strangest smell; almost like onions! It did fade some sun spots slightly but I found it hard to use because of the odor.
