Pimples can be caused by various factors, including hormonal changes, genetics, stress, and diet. Some common foods that are known to potentially trigger acne and pimples include high-glycemic foods such as sugary snacks, processed foods, dairy products, and foods high in saturated fats. It’s recommended to observe how your skin reacts to different foods and keep a food diary to identify any potential triggers. If you’re experiencing persistent acne, consider consulting a dermatologist for personalized advice and treatment options.
