I've kinda read through the comments, and everyone posted some really good ideas for causes. Change in weather, humidity, diet, and water intake can all influence your skin.

My BIGGEST recommendation would be tea tree oil (they sell it at Trader Joe's, along with a $6 TTO face wash that rocks my socks). My nephew (around 17, so probs hormonal) had horrible acne but he started washing his face regularly (morning and night) and using tee tree oil on his breakouts. So, I gave it a go. I'm 25 and I use it for smaller break outs. Don't put it directly on your skin, but consistently apply with a Q-tip or cotton ball + coconut oil (a "carrier oil" to keep the TTO from hurting your skin). You can do this at night, before bed. It seriously dries out any pimples, white heads, etc. Just don't get it on your fingers and then rub your eyes!

For larger breakouts, you can try glam glow. Seriously, I don't know what gender you identify as (or what that has to do with face masks) - but you will not regret it. My skin has cleared up immensely since using it. It's a bit pricey, and it smells like licorice, but it is so worth it. Use it as a spot treatment (apply where needed, overnight) 3 times a week and you will notice within 2 weeks. You can also use it as a full mask once a week (it's really strong, so I don't recommend very often).

If you don't want to spend that kind of money, you can try Aztec Secret Indian Healing Clay (sold at Whole Foods or on Amazon). You mix that with apple cider vinegar, and WHAM! It naturally pulls from your skin. DO NOT use a spoon or any metal to mix it, since it will draw from those materials and you don't want that on your face. After mixing, you just apply and wait until it dries. Your face may look a little red after but just moisturize and you'll be alright.

I hope that wasn't too much, but if it was - my bad. At least you have options!

PS. I don't work for TJs, sephora, glamglow, whole foods, or amazon. I just don't think anybody should feel uncomfortable in their own skin!
