NULASTIN Eyelash & Brow Serum Dual System — 2-Pack (0.1 fl oz) with Keratin & Peptides for Fuller Lashes and Thicker Brows

NULASTIN Eyelash Serum & Brow Serum is a two-step lash and brow treatment formulated with keratin, peptides, and elastin-supporting ingredients to help reduce shedding and encourage the appearance of fuller, longer lashes and thicker brows.

This dual-system kit contains one eyelash serum and one eyebrow serum, each in a 0.1 fl oz tube, designed to work together to target visible shedding and the look of hair density. The formulas are built around elastin-replenishing science plus supportive actives such as keratin and peptides, aiming to improve the condition and appearance of hairs over time when used consistently. Results in clinical testing have been observed in as soon as six weeks, with recommended twice-daily application until desired results are achieved.

How does the eyelash serum support longer-looking lashes?

The lash serum combines five active ingredients chosen to encourage length appearance and reduce breakage. It conditions lashes, replenishes elastin support, and adds keratin-derived nourishment to help hairs look stronger and shinier.

• Apply a thin line above the upper lash line for targeted delivery.
• Five-actives blend aims to reduce visible shedding and improve length appearance.
• Keratin and peptides work to condition and strengthen lash fibers.
• Use twice daily, then once daily for maintenance.

What benefits does the eyebrow serum provide for sparse or thinning brows?

The eyebrow formula focuses on reducing visible hair loss and supporting thicker-looking brows by rejuvenating elastin and supplying peptide and keratin support. The applicator brush makes it easy to place product precisely along the brow and onto skin where hair density is desired.

• Brush-tip applicator for controlled, even coverage on brows and skin.
• Targets visible shedding to help brows appear fuller and better shaped.
• Peptides and keratin help condition hairs and the hair anchor structure.
• Twice-daily use recommended until results are reached, then taper to once daily.

How do you use the dual system safely and effectively?

Use each product exactly as directed: the eyebrow serum is brushed into brows and onto skin where needed, while the eyelash serum is applied as a thin line above the top lash line. Consistent application twice daily helps optimize visible improvements; once your preferred look is reached, reduce to daily maintenance.

• Cleanse face and remove makeup before application.
• Apply eyebrow serum with brush to brow hairs and surrounding skin once in morning and evening.
• Apply eyelash serum as a precise thin line along the upper lid each morning and night.
• Allow product to dry before applying other eye cosmetics.

What kind of timeline and results can users expect?

Clinical testing for this NULASTIN duo reported visible changes in as soon as six weeks with continued improvement over time. Individual results vary depending on starting condition and frequency of use; many users report reduced shedding and an improved appearance of length and fullness when following the application routine.

• Visible improvements commonly noted around six weeks in clinical testing.
• Continued use can support longer-term maintenance of results.
• Reduce to once-daily application after achieving desired look.
• Store according to label instructions to maintain formula stability.

This kit is formulated around NULASTIN's elastin-focused approach to hair enhancement and pairs targeted eyelash conditioning with a brow-renewing brush serum for a complete eye-hair routine. Ingredients like keratin and peptides are included to nourish and support hair appearance without claims beyond improved look and reduced visible shedding.

Who is this for: This dual serum set is suited for people wanting to address visible lash shedding, enhance the appearance of lash length, or improve the look and shape of thinning brows. It is a good option for those seeking a targeted, science-backed cosmetic regimen compatible with daily beauty routines—especially users who prefer a separate, precise applicator for lashes and a brush for brows.
