May have gotten a wrong batch

I received a full size free sample of this to try and review. It looks like a full coverage buildable formula. I tried it on a piece of fruit and it covered blemishes well. The reason for my low rating is because the bottle I received had black strings or streaks in it. Not sure what they were as the were not mixing with the foundation formula no Matt how much I shook it. May have gotten a wrong batch.

Not for me

Im always searching the right kind of foundation for my skin type. I purchased this product with high hopes but sadly I was disappointed. I have a few sun spots and by noon they are showing again. I guess the search for a great foundation continues.
