I prefer black coffee, and the light, nutty flavor enhances my coffee just enough. You do need to make sure it’s well mixed, so I use a mini immersion frother. It took a couple weeks to see results, and it seems to help smooth and plump my skin. I did break out a little within a couple days of starting the collagen boost, so cut down to 1 tbsp, which has been working well. I almost never break out, which is why I believe it was because of the collagen boost, hence 4 stars.
