That’s because acne triggers can be anywhere and anything, depending on your sensitivities. Everyone’s skin responds differently when exposed to different environments so you may find that new things you introduce to your skin can trigger acne for you.

Here’s a list of not-so-common acne triggers that you could be exposing your skin to.

Synthetic hair: Sometimes hair used for braiding and protective styles can be treated with chemicals that irritate the skin and clog the pores. Keep that in mind when you get those summer braids!

Not covering your hair when you sleep: The oils and products we use in our hair can stain our pillows and clog our pores when we sleep on them every night. If you get frequent breakouts on your cheeks, try covering your hair at night or pulling it up and away from your face in a bun.

Products for natural hair: Many of the products for curly and kinky hair are made with heavy oils that clog the pores. Try to avoid wearing your hair down or in your face often.

Dairy products: Cow’s milk contains hormones that cause inflammation in the human body, which causes puffiness and clogged pores in the skin. Try swapping for dairy-free products instead for 30 days and see if that makes a difference in how frequently you break out. Goat cheese is OK!

You’re stressed. How do you know if you’re stressed out? Many of us don’t know we’re stressed because we’re not going through anything catastrophic, but every big change can be stressful, even good change. Starting a new job can be stressful. Buying a house can be stressful. Planning a wedding can be stressful. Be sure to check in with yourself and find time to ground yourself. Don’t let a catastrophic event be the only reason you take a break.

These are just a few of the places for acne triggers to hide. Be sure to talk to an esthetician who can personalize a skincare routine for you and suggest better skin habits based on your needs.
