NULASTIN Lash & Brow Dual Serum Kit — 2-Pack (0.1 fl oz each) with Keratin & Peptides for Fuller Lashes & Brows

NULASTIN Eyelash Serum & Brow Serum is a two-piece daily regimen designed to help reduce visible shedding and support the appearance of longer, fuller lashes and more defined brows.

Designed as a paired kit, this dual system contains a targeted eyelash serum and a complementary eyebrow serum (0.1 fl oz each). Both formulas blend keratin, peptides and elastin-replenishing technology to condition hair and the surrounding skin. The products are clinically tested for visible improvement timelines and arrive in an optimized applicator for precise, easy application.

How soon will I notice changes in my lash and brow appearance?

Results vary by individual, but many users report visible improvement within about six weeks when used as directed twice daily. The clinical testing cited by the brand focused on signs of reduced shedding and the look of increased length and fullness rather than guaranteed regrowth.

• Typical observations: diminished fallout and a fuller visual profile.
• Use schedule: twice daily until desired look, then once daily for maintenance.
• Consistent application is key for steady improvement.

What are the key ingredients and how do they work in each serum?

The formulas combine keratin and peptides alongside elastin-targeting technology to nourish hairs and the skin that supports them. The eyelash serum focuses on conditioning and reducing breakage to support longer-looking lashes, while the eyebrow serum targets shedding and shape for thicker-looking brows.

• Keratin: helps strengthen the hair shaft and reduce brittleness.
• Peptides: support the appearance of healthier, more resilient hairs.
• Elastin-focused actives: aim to improve the hair’s anchoring environment.

How do I apply the lash and brow serums for best results?

Apply each serum as instructed: a thin line of the eyelash serum along the upper lash line and brush the eyebrow serum across brows and the skin beneath them. Start with twice-daily use, then reduce to once daily once you achieve your desired look.

• Eyelashes: apply a fine line above the upper lash base, avoiding the eye itself.
• Eyebrows: use the brush-tip tube to coat hairs and skin where needed.
• Maintenance: switch to once-daily to preserve results after reaching goals.

Are there any safety or compatibility considerations?

These topical serums are formulated for cosmetic enhancement of brows and lashes. As with any concentrated active formula, perform a patch test if you have sensitive skin and discontinue use if irritation occurs. Avoid direct contact with the eye; rinse thoroughly if product enters the eye.

• Patch test recommended for sensitive skin types.
• Keep product out of eyes and rinse if contact occurs.
• Consult a dermatologist for concerns about ingredients or reactions.

Who is this for? This dual system is suited for people wanting to reduce the appearance of lash and brow shedding and improve the visual fullness and definition of natural hairs without pigments or tinting. It’s aimed at anyone seeking a targeted, science-forward cosmetic routine component—those with daily-care habits who will use the serums consistently are most likely to notice the intended effects.
