Brainstorming Post Ideas for a Product Launch Week

Launching a new product requires a carefully sequenced series of posts that build anticipation, announce, and then reinforce value. The reason behind each post matters: teaser posts create curiosity, announcement posts drive traffic, and follow-up posts handle objections. I am planning a five-day launch sequence for a handmade skincare line and need fresh angles. Should I focus on behind-the-scenes content showing the making process, or lean into customer testimonials from beta testers? My audience is primarily women aged 25 to 40 on Instagram and TikTok. I want each post to feel purposeful rather than repetitive. What content formats have worked best for your launches? Carousels, reels, stories, or a combination? Share your launch post structures and let us refine them together in this thread.
