NULASTIN Lash & Brow Dual Serum System — 2-Count 0.1 fl oz Tubes with Keratin & Peptides for Fuller-Looking Lashes and Brows

NULASTIN Eyelash Serum & Brow Serum is a two-product system formulated with keratin, peptides, and elastin-supporting ingredients to help lashes and brows appear fuller and less prone to visible shedding.

This dual set pairs a lash-enhancing serum and a brow-renewing serum designed to target the look of length, thickness, and reduced shedding. Each 0.1 fl oz tube contains a concentrated formula optimized for its application area: a thin-line eyelash conditioner for the upper lash line and a brush-tip eyebrow serum for precision brow shaping. The approach focuses on replenishing elastin-related support proteins alongside conditioning agents so lashes and brows appear healthier and more defined with regular use.

How quickly should I expect to see changes in lash and brow appearance?

Visible improvements can appear within several weeks for many users, with the brand noting potential results as soon as six weeks in clinical testing. Individual results vary by hair type, baseline condition, and consistency of application.

• Clinical testing reported noticeable differences around six weeks.*
• Daily twice-daily application recommended until desired look is achieved.
• Maintenance reduces to once daily after reaching results.

What are the key ingredients and how do they work for lashes and brows?

The formulas combine keratin, peptides, and elastin-supporting actives to strengthen and condition hairs while helping reduce visible shedding. These ingredients are selected to work together: keratin for hair structure, peptides for support, and elastin-replenishing components for the hair anchoring environment.

• Keratin supports the hair’s structural integrity and surface appearance.
• Peptides help provide targeted support where hair growth and retention matter.
• Elastin-focused ingredients are intended to improve the hair anchoring environment.

How do I apply each serum safely and effectively?

Application differs by product to deliver optimal coverage: the eyelash serum is applied as a thin line along the upper lash line, while the eyebrow serum uses a brush applicator for targeted strokes on brows and adjacent skin. Use on clean, dry skin and avoid contact with the eye itself.

• Wipe away makeup and residue before applying.
• Apply eyelash serum as a thin line above the top lash line once or twice daily.
• Brush eyebrow serum through brows and onto sparse areas using short strokes.
• Reduce to once-daily maintenance after the desired look is achieved.

Are there any safety or compatibility notes I should know?

The dual system is formulated for external use around the eye area; avoid direct eye contact and discontinue use if irritation occurs. Because formulas can interact with other topical treatments, check compatibility with existing eye-area products or consult a professional if you have specific sensitivities.

• Do not apply inside the eye; rinse with water if contact occurs.
• Patch-test new topical products if you have sensitive skin or conditions.
• Follow package directions for frequency and application technique.

Who is this for: This NULASTIN Lash & Brow Dual System suits people seeking non-invasive, topical conditioning for lashes and brows — especially those wanting to address visible shedding, improve lash length appearance, and shape fuller looking brows. It’s aimed at users prepared to follow a daily routine and monitor results over several weeks. Those with eye disease, recent surgery, or on certain medications should consult a healthcare professional before use.
