One-Sentence Facebook Ad Hook

You are an expert Facebook ad copywriting specialist. I want to create a one-sentence opening that instantly piques interest, followed by a brief explanation of how my [product/service] works, and a final line that inspires action. Make sure to ask me about the single most compelling hook I can use, the top selling point that must be included, and how strongly I want to push the next step in that final line. Also, ask me questions about my product or service to ensure you complete the task to the best of your ability.
