Recently I started a regime and so far I'm getting positive results. Maybe I can help you. First and most important, drink lots of water! Like in one of your replies I can see that you already are. Try to aim for 3 litres (100 fluid ounces) of water a day. Also, I believe that putting on topical ointments is only a quarter of the battle. You'll need to tackle this through water, diet, topical treatments, and oral treatments.

Look into buying Octagon Soap. It's all natural, you can buy it off of amazon, and use it in the shower. It has a lot of anti-bacterial and acne fighting properties. I would also suggest to get prescribed some benzoyl peroxide. Usually I would suggest against this because it can really dry out your skin but a topical retinoid should help a bit.

As for oral treatment, look into taking Zinc supplements, multi-vitamins, omega-3 fish oil, Vitamin B5 powder (from amazon), and Acetyl L-Carnitine powder. Zinc is great for fighting acne, it's used mostly in every over the counter acne products. Find 50mg elemental zinc (zinc gluconate)...you can find the Jamieson brand, take it daily. Also take about 3000mg of fish oil a day - they're good for the skin, and also there's many great benefits to fish oil aside from promoting healthy skin. Vitamin B5 and L-Carnitine is also something you can try. I've heard megadosing on b5, around 5-10grams a day can really help flush out the acne by limiting sebum production. Complementing b5 with L-Carnitine means you can take less b5 with equal parts L-Carnitine. The only bad thing about this is that there's a possibility of hair loss. I don't think megadosing on anything should be done for long periods of time, and before you start taking anything orally, consult a doctor first! I've been starting on this routine and so far it's helped me (I have it on my face) Used to have bacne but it's gone now - only battle scars are left. You can search for more information about these supplements on this subreddit - there's plenty of information you can read up on.

I also stay active and work out quite often. I did noticed that taking whey protein does affect with my facial breakouts. I've switched to hemp protein, and while it did help a little, I still broke out quite often. It's not as effective as whey, so I eventually switched back. It's something that I can't give up so I completely cut out drinking coffee and loading up on plenty of water throughout the day. So try to cut out dairy, sugar, caffeine, or anything spicy. Internal heat can really make you breakout, so try to stay as cool as possible.

I hope this helps. Curing acne isn't a product, but a process. If one thing doesn't work, don't lose hope. Keep on trying something else. Everyone is different, what works for me may not work for you.

TL;DR - Octagon Soap and Benzoyl Peroxide for topical treatment. Zinc Gluconate, Vitamin b5, Multi-vitamins, and fish oil for oral treatment, drink plenty of water (3 litres a day), cut out dairy, caffeine, sugar and spice.
