Nu Colour® Lash + Brow Serum (Singapore)

Nu Colour Lash + Brow Serum is a peptide-based growth serum applied nightly to the lash line and brows, designed to improve length, thickness, and fullness over a 4–8 week treatment period. At S$65, it's positioned as a long-term alternative to lash extensions — which run S$80–S$150 per session in Singapore and need refills every 2–3 weeks. The serum strengthens existing hairs and supports the growth cycle, so results build cumulatively with consistent use.

What Makes Nu Colour Lash + Brow Serum Different

Singapore has one of the highest concentrations of lash extension studios in Southeast Asia — a quick walk through Bugis Junction, Orchard Gateway, or any neighbourhood mall confirms that. Extensions look great initially, but the maintenance cycle is expensive (S$60–S$100 per refill every 2–3 weeks), time-consuming (60–90 minutes per appointment), and the adhesive plus weight of synthetic lashes gradually weakens natural lashes over time. Many people find their natural lashes are thinner after 6–12 months of extensions than when they started.

Lash + Brow Serum works the opposite way — instead of masking thin lashes with synthetic alternatives, it strengthens and lengthens the lashes you already have. The peptide complex targets the hair follicle during its growth phase (anagen), extending the period of active growth so each lash reaches greater length before naturally shedding. Results aren't instant like extensions — you're looking at 4–6 weeks for noticeable improvement — but the improvement is real growth, not cosmetic overlay. And since it also works on brows, you're treating both areas with one product.

Key Ingredients

Biotin (Vitamin B7): An essential B vitamin directly involved in keratin production — the structural protein that forms hair, lashes, and brows. Biotin deficiency is a documented cause of hair thinning, and topical application delivers the vitamin directly to the follicle where it's needed. Clinical research shows biotin supports the structural integrity of the hair shaft, reducing brittleness and breakage.

Peptide Complex: Short-chain amino acid sequences that signal hair follicles to extend the anagen (growth) phase. The human lash growth cycle is approximately 30–45 days in the anagen phase, followed by 15 days of catagen (transition) and 100+ days of telogen (rest). By extending the anagen window, lashes have more time to grow longer before entering the shedding phase. Published trichology research shows peptide-based serums can increase lash length by 25–40% over 8–12 weeks.

Conditioning Agents: The serum base includes panthenol and glycerin to condition and hydrate both the lashes and the delicate skin of the eyelid. In Singapore's humid environment, where rubbing eyes due to sweat, heat, and airborne irritants is common, conditioned lashes are more resistant to mechanical damage from friction.

How to Use

Apply once daily, at night, to clean lashes and brows. Use the precision applicator to sweep a thin line of serum along the upper lash line — similar to applying liquid eyeliner. For brows, brush the serum through the full brow area using short strokes. One swipe per eye and per brow is sufficient; more product doesn't accelerate results.

Apply as the last step of your evening skincare routine, after all creams and treatments have absorbed. Avoid rubbing your eyes for at least 5 minutes after application. If you wear contact lenses, remove them before applying and wait at least 15 minutes before reinserting. The serum absorbs fully within 2–3 minutes and doesn't leave residue on pillowcases.

Consistency is everything. The growth cycle means you won't see visible changes in the first 2–3 weeks — results typically become noticeable at the 4–6 week mark, with full results at 8–12 weeks. Skipping days delays results proportionally, so set it alongside your nightly routine (after brushing teeth, before bed) as a non-negotiable step.

Frequently Asked Questions

How is this shipped in Singapore?
Orders ship from the official Nu Skin Singapore warehouse. Delivery is S$4.99 flat rate, or free on orders over S$99. Delivery takes 1–3 business days.

How long until I see results?
Most users notice improved lash thickness at 4–6 weeks and meaningful length increase at 8–12 weeks. Full results require consistent nightly application — gaps in use extend the timeline proportionally.

Can I use it with lash extensions?
It's best to use the serum on natural lashes without extensions. Extensions and their adhesive can interfere with the serum's absorption. Many users switch to the serum specifically to grow their natural lashes strong enough to stop needing extensions.

Is it safe around the eye area?
Yes, the formula is ophthalmologist-tested for use near the eyes. If any serum gets directly in the eye, rinse with clean water. Some users experience mild tingling on first application — this is normal and typically resolves within a few days.

How long does one tube last?
With the recommended single nightly application to both lash lines and both brows, one tube lasts approximately 8–10 weeks — conveniently aligning with the timeframe needed to see full results.

Important Information

Important Information: For external use only. Avoid contact with eyes. If irritation occurs, discontinue use and consult a healthcare professional. Patch test recommended before first use. In Singapore's high-UV tropical environment, always use broad-spectrum SPF protection alongside any skincare routine. Individual results may vary based on skin type and consistent use.
