Acne can be caused by various factors such as hormonal changes, genetics, improper skincare, stress, and diet. If you are experiencing acne, it does not necessarily mean you are lacking something specific. However, a balanced diet with essential nutrients like vitamins A, C, E, and zinc can help promote healthy skin and reduce acne symptoms. Maintaining good hygiene practices, staying hydrated, and managing stress levels can also contribute to clearer skin. If acne persists, it is best to consult with a dermatologist for personalized advice and treatment options.
