[skin concern] Anyone have any negative experiences while taking powdered collagen?

I started taking Organika's Enhanced Collagen powdered (grass fed source) 13 days ago and I have noticed that I've had 3 new pimples show up since then. I'm also taking magnesium supplements along with it so I've decided to stop taking both until my skin gets clear then reintroduce them individually and see what happens. I've also been stressed more than usual with the current state of reality so that could be a factor as well.

Has anyone taking collagen powder and noticed any side effects? I've seen improvements in my eyelashes and nails it's just that I've been getting more pimples.
