01 · The challenge

Glowform sells a single serum that replaces a five-step routine. Paid social had stalled: the same four ads were running on repeat and cost per acquisition had climbed for three months.

02 · Our strategy

We mined 2,000+ reviews and competitor comments and found that buyers talked about time saved, not ingredients. We built 20 hooks around that angle and matched five creators aged 25 to 40 who already used minimal routines.

03 · Hooks we tested
  • “I stopped using 5 serums for this one”Winner
  • “Nobody tells you this about skincare”Winner
  • “My 30-second morning routine”Winner
  • “Dermatologist reacts to my routine”Retired
  • “5 reasons you need this serum”Retired
04 · Execution
  • 5 creators matched in 48 hours
  • One weekend shoot
  • 18 ads live by Monday
  • Formats for TikTok, Reels and Meta feed
  • Whitelisted from creator handles
