Hi, again-
I'm the one that told you about the coconut oil in the other posts. I'm 30 and have had acne as an adult (not as a teenager). I have been on and off birth control and have had the same problems so I don't think mine is hormone driven.
My skin has finally improved this year. My coconut oil recommendation actually came from a facialist. She recommends to wash your face with something very gentle, then spray with mineral water, then use the coconut oil. The oil is has antibacterial and antifungal properties so that's why it's good for acne.
I also used a cream cleanser that I got from Whole Foods. It was organic, very mild, and made from coconut water. I think other cleansers have gotten us used to wanting that squeaky clean, almost dry feeling on our skin, but I don't think that's what mine needed. I have naturally dry to regular skin so stripping all the oils away, broke me out worse, I think.
Often, acne signals an internal problem. Mine got a lot better when I cut out almost all grains and carbs (other than vegetables). Also, I try to eat/drink fermented foods to get the good baceterias for my gut. I also think that has helped a lot. I also think avoiding dairy has helped. Take a look and research the makeup you're using, that could also be causing problems.
I also have used a homemade mix of sea salt and lemon juice for my skin. That can be kind of harsh and I wouldn't use it everyday.
My skin has definitely responded the best to very simple and pure products. I have gone the high end route and got mixed results. The do-it-yourself products that I have used have worked the best. If you are able, try to see an experienced facialist (can't remember the real term). They can be expensive but there are always groupons and deals for their services.
I hope you figure something out. It's hard because it takes a few weeks to see if something will work.
