When your period rolls around, breakouts often follow. For many women, it feels like a monthly ritual: a few days before or during your period, acne shows up along the jawline, chin, or cheeks. While hormonal changes are the main culprit, dermatologists point out that certain foods can make these breakouts worse. Here are three common dietary triggers for period-related acne.
High-Glycemic Carbohydrates
Foods that cause a rapid spike in blood sugar—think white bread, sugary cereals, pasta, and pastries—are high on the glycemic index. According to dermatologists, these foods can increase insulin levels, which in turn may boost oil production and inflammation in the skin. During the menstrual cycle, when hormones like progesterone are already fluctuating, adding high-glycemic foods to the mix can create an environment where acne thrives. Replacing refined carbs with whole grains, legumes, and vegetables may help keep breakouts in check.
Dairy Products
Milk, cheese, and other dairy products have been linked to acne in several studies, though the evidence isn't conclusive for everyone. Dermatologists explain that dairy may stimulate the production of insulin-like growth factor 1 (IGF-1), a hormone that can increase sebum production and skin cell turnover—a recipe for clogged pores. For some women, cutting back on dairy during the luteal phase (the week or two before their period) can reduce the severity of breakouts. Full-fat and skim dairy appear to have similar effects, so switching to plant-based alternatives like almond or oat milk might be worth a try.
Foods High in Added Sugars
Sugary snacks, sodas, and desserts don't just affect your energy levels—they can also affect your skin. Added sugars can spike blood sugar and insulin, similar to refined carbs, leading to more inflammation and oil production. Chocolate itself, especially milk chocolate with lots of added sugar, is a common acne trigger reported by many women. Dark chocolate with a higher cocoa content (70% or more) may be a better option, though it still contains sugar. Keeping an eye on your sugar intake around your period may help your skin stay calmer.
While diet can influence acne, it's rarely the sole cause. Hormonal changes, stress, and skincare routines all play roles. A balanced diet paired with consistent skincare can make a noticeable difference.
How to Adjust Your Diet Without Feeling Deprived
You don't need to cut out these foods entirely. Instead, try moderation and timing. If you know your period is approaching, be mindful of your intake of sugary drinks, dairy-heavy meals, and refined carbs. Pair carbs with protein or healthy fats to slow blood sugar spikes. Water, herbal teas, and whole foods can support your skin from the inside. As always, talk to a dermatologist for personalized advice—everyone's triggers are different.
