7 Causes of Teen Acne Every Parent Should Know
Acne is one of the most common, and frustrating, skin concerns among teenagers. While it’s often seen as a normal part of growing up, understanding what triggers acne in teens can empower parents to take early, proactive steps. If you’ve found yourself searching for answers, you're not alone. Here are seven key causes of teen acne that every parent should know.
1. Hormonal Changes During Puberty
One of the leading causes of teen acne is the natural hormonal shift that happens during puberty. As androgen hormones (like testosterone) increase, they stimulate the skin’s oil glands to produce more sebum (oil). While oil is essential to keep skin hydrated, too much of it can clog pores, leading to breakouts. This type of hormonal acne in teens is typically found on the forehead, nose, and chin; commonly known as the T-zone.
2. Overactive Oil Glands
Teens often have oilier skin due to increased hormone levels. Excess oil mixes with dead skin cells and bacteria on the skin’s surface, creating the perfect storm for acne. If your teen has noticeably oily skin and frequent blackheads or whiteheads, their oil glands may be working overtime.
3. Clogged Pores and Poor Skin Hygiene
While acne isn’t caused by dirty skin, poor skin hygiene can definitely make it worse. Teens who don’t cleanse their face regularly, or who sleep in makeup, are more likely to experience clogged pores. Using the wrong skincare products, especially harsh scrubs or heavy creams, can irritate the skin and lead to more breakouts.
Encourage your teen to use a gentle, non-comedogenic (won’t clog pores) cleanser twice a day, and never sleep with makeup on. Always check the ingredients for pore cloggers, even when it says "non-comedogenic". Get a FREE List of pore clogging ingredients HERE
4. Diet and Nutrition
More and more research is pointing to a connection between diet and acne. While the exact relationship is still being studied, we do know that foods high in sugar, dairy, and processed carbs can contribute to inflammation in the body. For many teens, this can mean more frequent breakouts.
Parents can support their teen by offering more skin-friendly meals that include whole foods, leafy greens, healthy fats, and plenty of water. Tracking food intake and skin reactions can help identify personal acne triggers. A food log is helpful.
5. Stress and Lack of Sleep
Teens today are under more pressure than ever, from academics and extracurriculars to social media and peer dynamics. Stress increases cortisol, a hormone that can lead to increased oil production and inflammation, both of which can worsen acne.
Encouraging your teen to prioritize sleep, practice relaxation techniques and take breaks from screens can make a noticeable difference in their skin and overall well-being.
6. Genetics and Family History
Sometimes, acne is simply in the genes. If you or your partner struggled with acne as teens, there’s a higher chance your child may experience it too. While you can’t change genetics, understanding this factor helps set realistic expectations and may encourage earlier intervention to manage symptoms effectively.
7. Pore-Clogging Products (Cosmetics and Haircare)
Another often-overlooked cause is the use of pore-clogging products. Teens may use makeup, sunscreens or even hair products that contain ingredients like mineral oil or silicones that can trigger breakouts along the forehead, temples, and jawline.
Parents should look for the label “non-comedogenic” and check the ingredient list on all skincare and haircare products used by their teen.
Understanding what triggers acne in teens helps remove the mystery and frustration from the process. Whether it’s hormonal acne in teens, poor diet, or lifestyle factors, there’s often more than one cause at play. As a parent, you don’t have to have all the answers, but you can provide the guidance and support your teen needs to start their journey toward clearer skin.
