I just wanted to put my two cents in for the discussion.

So, I'm 26.
When I was 13 I started having acne, so my doctor put me on the pill - Yasmin - which I continuously took until September 2014, when I took off for a trip around Asia. 5 monthsin Asia, humid air, salty water, freedom and all those backpacker's ideals - so I thought that I didn't need anything (not even deodorant... yeah).While out of the pill I had cramping and heavy, not very regular periods.

I had been clear of acne for several years, only one or two pimples sometimes. I even took Roacutan during my teens. After stopping the pill, I continued clear for some months, until around March/April 2015. My skin went downhill from then on. In June I couldn't take it anymore - I went back on the pill Yasmin.

Worst decision ever. I had huge side-effects that I had never had before. I was a hormonal, depressed and no libido caos. I changed the pill, to Microgynon, which kept me in that same exact caos, but added me extra weight and bloating. I couldn't take it anymore. It even started to take a toll on my relationship. I started researching and creating a plan to go off the pill again. I tried to identify the common mistakes that are made and the ones I personally made. And I reached a conclusion.

When I stopped the pill,I was drinking a lot of healthy shakes, full of vegetables, stopped eating dairy and gluten, reduced sugars and red meats, took a bunch of vitamins, supplements, superfoods...And that's all great, super healthy (if done properly) and helpful in the long run - meaning, it takes time to actually have an effect. And acne is far too destructive to "wait it out".

At the same time, I was not taking care of my skin directly. In the first months, following the "backpacker's ideals", I was not even washing my face properly, let alone have a stable regimen of moisturizers and cleansers.I did nothing other than a random scrub one time, a random mask another time, a random moisturizer every other week, things that I would research but discard when it didn't have a dramatic effect. Skin needs stability and I was surprising it every other month.
Coming back to real life, I realise now that you need to take care of your actual skin if you have an unbalance, like we do.

Now, only 6 months after restarting the pill, on December 2015 I stopped again.
It's been 3 months now, only had 1 period and my skin started to go south again, but I managed to control it. It's now really good and clear.
I've been taking, every morning for the last 1 and 1/2 months, Zink (30mg) , Vitamin D (I live in Denmark, so, yeah, no not that much sun) and Evening primrose oil (1300mg).
I kind of follow the acne.org regimen, but with products from around my place (too much work ordering stuff from the States - and expensive). So, cleanser and moisturizer (with jojoba) twice a day, and a small dose of BP at night. A gave a LOT OF ATTENTION to the ingredients when choosing my products: focused on non-comedogenic stuff. In my "all-natural" fase, I though "oh coconut oil seems really nice - let me smear that all over my face and body and hair". Big mistake - it's highly comedogenic. Even when I put in on my body or hair I have to be extra careful not to let any of it touch my face, or a break out is sure to follow.

Basically the point I'm trying to get across is that we tend to think we will fix this by trying to eat differently, cutting specific foods or taking supplements and vitamins. But that is simply not enough. So, my plan consist now on the following:
1) Cleanse and moisturize twice a day and do the Benzoyl Peroxide once a day, at night, in specific areas. If consistently clear, do BP every other day.But always moisturize! Except every 3 days, when usingGlycolic acid at night.
2)I would advise not to scrub, as I noticed that whenever I scrub a breakout happens. Salicylicacid makes me break out as well.
3)Use gentle products, NON-COMEDOGENIC - and jojoba oil for me is a great addition to any moisturizing cream.
4) Take zink. It's backed by several scientific studies, it does make a difference. I take Evening Primrose Oil, even though I read a lot of studies that point out that it's really useless - but somehow I want to give it a try.
5)Do research - actual research, in scientific studies, not only in random blogs. Be critic.
6)When or if the acne gets worse, adjust, but not completely change your regimen. The key is stability.
7)Do eat healthy and exercise. Less sugar and processed foods and no dairy.

I am aware that the worse is yet to come. Only after 5/6 months did I start feeling the acne coming back strong. The thing is... this time I have a plan, this time I'm prepared. I have a stable regimen, gentle products, good diet and supplements. I have an all-round strategy. Let's see and hope for the best!
