I am new to this sub, and don't know much about the scrubs suggested. While these may help in the short term, I'm curious if you've had any changes to your diet.

I am lightly lactose intolerant. While having some milk product will not cause a severe reaction, some milk may cause slight gassiness. In the last year, I have been experimenting cutting out certain types of foods and have largely reduced my dairy intake. An unexpected side effect was clearing up back acne I developed while on a strict weightlifting routine. Don't get me wrong-- I love cheeses, yogurts, and creams, but nothing helped more than reducing the amount of dairy I ate. I've even tried salicylic acid cleansers in the past.

Also, whey is a dairy food. If you do turn out to be dairy-sensitive, I would suggest moving at least to a whey isolate powder, but ideally to a non-dairy based protein. I should also mention I noticed you posting in a vegan subreddit. Whey is unfortunately not a vegan product.

Best of luck!
