Unless it's an an allergic reaction. Are you eating a new type of vegetable?
An allergic reaction can also be from changed laundry detergent, new sheet/blanket, plant(s) nearby, etc.
Or if you are a teenager it could just be a new change in your body chemistry (no fun, but it should stabilize in a few years).
I would look for any possible external sources (sheets etc.) and other than that I would start a cleaning regimen like this one that helped me:
One or more times a day wash with a mild soap and warm water using a wash cloth, rinse with warm water, rinse with vinegar, pause for 20-30 seconds or so, rinse with cold water, blot dry.
-The vinegar shrinks your pores and kills bacteria while not drying out your skin.
I am my own bad companion
I can't say for certain that the acne was all diet related, as I've been suffering a great deal of stress over the last few months.
I have reduced my soy/mock meat intake, and have had microdermabrasion to unclog my pores. I also bought a few acne treatments, one being a tea tree topical antiseptic (which is great for drying out the spots) and the 'acne cleansing cream' by Moo Goo (I swear by this one, my acne's reduced since using this).
I have always dealt with mild acne and it has never really been a problem. I would get maybe one or two small breakouts a month. It has been 1-2 weeks since I cut meat out of my diet and my skin has been freaking out! It has never been this bad in my life and no matter what I do it seems to be getting worse! I was wondering if anyone else has had this happen when they turned vegetarian?
I think its not the change of diet, eat a lot of fruits rich in V-C, before when I encounter acne I go to beach and burn it in the sun in the morning and apply some medicine for it, hot spring also help. If your place don't have hot spring you can boiled water mix with salt and apply it in the area affected then rinse it just make sure that the water is not too hot to burn your skin ok? Do it every morning and in the evening before you go to sleep.
I have acne breakouts too....my dermatologist told me to avoid nuts as it causes more oil production in the skin so perhaps you are eating more nuts now???? It can also be hormonal. I know for a fact, because my DR recently changed my hormones 4 months ago to include testosterone and lo and behold my skin went into overtime making bumps EVERYWHERE...face, neck, scalp, back. I quit taking them and it's finally clearing up..
I had the same thing happen i never had many break outs even as a teen. I'm 25 and now having a worse time with it. But at the same time i made the veggie switch i also changed face washes and my Dr changed my birth control. I changed my face wash back and nothing new so its either the meds or diet change. Thankfully a few weeks ago it started to clear up. I just started to wash up twice a day and like someone said i was eating a lot of tofu in the beginning. So i cut that out and now its better. You may just have to experment with things to see what works.

I'm going through the same thing right now. At first I thought it was hormones or something, even though I've never had an acne problem in my life, until someone at work told me that the same thing happened to them when they went vegetarian for a while. Eventually it should clear up. Mine is starting to get better already.
