Beta Results

Eight weeks. 125 testers. Real photos.

Before we released the Signal Serum, we ran a closed eight-week trial with 125 testers. They used the serum twice daily. We did check-ins at week four and week eight and took photos at both.

What the group saw

  • 83% saw improved radiance (average +2.0 points on a 10-point self-report scale).
  • 78% saw more even skin tone (+1.4).
  • 67% saw smoother texture (+1.4).
  • 65% saw improved firmness (+1.0).
  • 59% had someone else comment on their skin during the trial.
  • 94% found the twice-daily routine sustainable through eight weeks.
