NULASTIN Shape Altering Eyebrow Serum — Brow Enhancing Serum 0.1 fl oz, Strengthens & Defines for Fuller-Looking Brows

This lightweight serum targets thinning brows by replenishing key proteins and reinforcing the hair support structure so lashes appear denser and better defined. Designed for daily use, the formula comes in an updated clear tube with an optimized opening to help the brush pick up the right amount of product for precise application. Clinical testing supports visible improvements in brow density and thickness when used as directed.

How does this serum help brows look fuller and more defined?

The formula focuses on supporting elastin and other hair-strengthening components that help hair stay anchored and appear thicker. With consistent application, the brows look denser because fewer hairs appear to shed and the remaining hairs sit with better shape and alignment.

• Supports elastin replenishment to help hair anchor more effectively.
• Helps reduce the appearance of hair shedding for fuller-looking brows.
• Brush application smooths and shapes each brow for a sculpted finish.

How should I apply the NULASTIN brow serum for best results?

Apply to clean, dry brows and the skin beneath where you want improvement. Use the brush in a back-and-forth motion to coat hairs and skin, applying twice daily until the desired appearance is reached, then reduce to maintenance frequency.

• Brush onto brows and skin with a back-and-forth motion.
• Start with twice-daily use; lower frequency after achieved results.
• Clear tube and wider opening improve brush saturation and control.

What kind of results and timeline can I expect?

Individual results vary, but clinical testing showed measurable increases in brow density and thickness over a multi-week period when used consistently. Many users notice gradual improvement in fullness and reduced visible shedding within weeks, with more pronounced change after continued use.

• Clinically studied formula with reported improvements in brow density.
• Visible changes accumulate over several weeks of steady application.
• Maintain with reduced frequency once the desired look is achieved.

Is the packaging different from previous versions?

Yes — the limited-edition clear tube features a wider opening and a redesigned cap to improve brush saturation and make it easier to see remaining product. The new packaging keeps the same formula while offering more precise application and better fill visibility.

• Clear tube shows remaining product for easy monitoring.
• Wider opening enhances brush loading and control.
• Packaging improvement only; formula remains clinically studied.
