Bone broth WILL cure your acne forever.
I have been suffering with acne for 8 years, and it sucks. I've spent probably more than I should have on all the expensive creams, have gone to countless dermatologists, and still I had no luck. There were some products that seemed hopeful: Differin cleared most of my acne and scars at one point. But at the same time, I was never 100% clear.
Then I took a lot of time researching the real cause of acne, or at least what was causing mine, since it is not normal for a 20 year old to have acne. I realized that it was an internal problem; I wasn't properly digesting ANYTHING and it left me with multiple food intolerances. I had something called Leaky Gut, which many people in the western world DO have but just don't know about it. It is caused by many things, including stress, high sugar and yeast consumption, and much more.
When I was a kid, the only thing I would eat was fruit. I would have probably 10 oranges a day, which even though fruit is good for you, it is only good in moderation. With this, I realized that my diet when I was younger did in fact cause me to have this leaky gut.
To remedy this ailment, I took out dairy and gluten. I drink bone broth every day, as well as apple cider vinegar. My skin is clear and I am finally happy with my skin. Not only has it helped with my skin, but a slew of other things. I am getting massive gains from the GAPS diet I am on, mostly because all the protein in the bone broth and chicken I eat, my libido is great, and I don't have any anxiety or depression anymore.
If you truly want to cure yourself of acne and not just mask it, try bone broth. That is just one component of it though, but it will do wonders. Make your own at home, because the stuff that you buy at stores is overly processed and has no nutritional value.
Hopefully this helps someone out there, because I know how crappy it can be having acne. Hang in there.
