Skin Research Laboratories Brow Enhancing Serum 3.2 mL — peptide & biotin formula for fuller, stronger brows

neuLASH Brow Enhancing Serum by Skin Research Laboratories is a peptide- and biotin-enriched lash serum formulated to improve the appearance of length, fullness and strength with visible results in about 4–6 weeks.

Designed for people who want a science-backed, dermatologist- and ophthalmologist-reviewed lash treatment, neuLASH delivers a concentrated blend of amino acids, bioengineered polypeptides, biotin and botanical extracts. The lightweight, vegan-friendly formula is intended for nightly application at the base of the upper lashes and supports the look of healthier, more resilient eyelashes over continued use.

How quickly will I notice a difference in my lashes?

Most users report visible improvements within 4–6 weeks, with more pronounced length, volume and shine after continued nightly application. Results build gradually because the formula works with the natural lash cycle to fortify and condition each strand.

• Visible change usually begins in 4–6 weeks of consistent nightly use.
• Fuller-looking lashes develop as the formula strengthens and conditions over time.
• Maintain results by continuing use; once achieved, apply every other night.

What ingredients make neuLASH effective and safe?

The serum combines a proprietary peptide complex with amino acids, biotin and pumpkin seed extract to support the appearance of thicker, stronger lashes. The formulation is reviewed by dermatologists and ophthalmologists and is described as safe for contact lens wearers when used as directed.

• Bioengineered polypeptides and peptides to help condition and fortify lash hairs.
• Biotin (vitamin B) to support lash resilience and reduce breakage appearance.
• Pumpkin seed extract for a visibly fuller look and plant-based hydration.

How do I incorporate neuLASH into my routine?

Apply neuLASH nightly to the base of clean, dry upper lashes using a single swipe along the lash line. Continue nightly use until you reach your desired result; then transition to every-other-night maintenance to preserve the appearance.

• Use on clean, makeup-free upper lash line only; do not apply inside the eye.
• One 3.2 mL tube provides weeks of nightly applications depending on usage.
• Safe for most users, including contact lens wearers, when used as directed.

Will neuLASH work with other eye products or treatments?

neuLASH can be used alongside most cosmetic eye products, but you should apply the serum first and allow it to absorb before adding cosmetics. If you are undergoing medical eyelid or lash procedures, consult a healthcare provider before introducing new topical treatments.

• Apply serum to clean lash base and let it dry before layering other products.
• If you use prescription eyelash treatments, check with your clinician about combining products.
• If irritation occurs, discontinue use and consult a professional.

Who is this for: neuLASH Brow Enhancing Serum is suited for anyone seeking a non-invasive, science-informed way to improve the look of short, brittle, sparse or thin lashes. It is formulated for nightly cosmetic use, reviewed by eye and skin experts, and is a practical option for contact lens wearers and people preferring vegan-friendly, plant-enhanced beauty formulas. If you want gradual, maintainable improvement in lash appearance without makeup-dependent techniques, neuLASH offers a targeted serum backed by ingredient research.
