Loyalty: GRO Brow Serum

Benefits
  • Improves visible fullness in sparse or thinning brows
  • Supports long-term strength and vitality
  • Safe for use on tattooed and microbladed brows
How to Use

We recommend applying GRO Brow Serum twice daily for the first two months, then switching to once daily, in the morning or evening. In the morning, apply to clean, dry skin, prior to your makeup routine. In the evening, apply after you've washed your face and completed your skincare routine.

- Hold wand horizontally and apply gently along your brow line.
- Repeat daily, decreasing to once daily after two months.
- Replace your GRO Brow Serum every two months for freshness, safety and best performance.
