Bests & Worsts Reviews from Amazon

I rarely leave Amazon reviews but had to get on here to warn future buyers. I have tried numerous collagen powders but wanted to give this one a try because the price was so great. I quickly learned you get what you pay for. Within a couple weeks I started getting small bumps on my cheeks, I wasn't sure what it was from. Eventually this turned into a full on rash that was all over my face, neck, shoulders and upper back. Looked like severe acne and when I would get hot or sweat it would become incredibly itchy. I ended up putting two and two together and realized it was this powder and returned it. I went back to my pricier collagen powder and sure enough my rash went away, but it took 3 full weeks to recover from it.
