Nu Colour® Lash + Brow Serum (Canada)

Every February in Calgary, Edmonton, and Winnipeg, the same beauty problem surfaces: months of indoor forced-air heating, toque friction, and mascara layered over dry, brittle lashes have left the lash line looking sparse and fragile. Extensions seem like the answer — until the fills stop and natural lashes emerge even thinner than before. The Nu Colour® Lash + Brow Serum (CA$49.90) is a nightly peptide-based conditioning treatment formulated to support healthier growth conditions at the follicle level, helping lashes and brows appear fuller, thicker, and less prone to breakage over a consistent 6–8 week cycle. One precision applicator. No microblading. No prescription required.

Best suited for: Lashes thinned by extension use, nightly mascara wear, or months of dry Canadian indoor heating; brows sparse from over-plucking, hormonal shifts, or natural ageing; anyone seeking a non-invasive peptide alternative to prostaglandin-based serums

Less suited for: Anyone requiring a medically licensed prescription growth treatment; those with active eye infections, severely irritated lash lines, or recent eye surgery

Pairs well with: Nu Colour Curl & Lash Mascara (CA$23.00) for daytime definition; ageLOC® LumiSpa® IdealEyes (CA$48.00) for the surrounding eye area

What Makes Nu Colour® Lash + Brow Serum Different

Most drugstore lash serums centre on panthenol alone — a basic conditioning agent that coats the hair shaft without addressing the follicle environment. The Nu Colour® Lash + Brow Serum combines two targeted ingredient categories that work at different levels of the lash and brow structure:

Peptide Complex

Peptides signal the follicle environment to support the conditions associated with healthy hair growth. Rather than relying solely on surface conditioning, the peptide complex in this serum targets the visible density concern at a structural level — supporting fuller-looking lashes and brows over repeated nightly application through the natural growth cycle.

Conditioning Agents

Existing lashes and brow hairs are nourished and strengthened by a blend of conditioning agents that reduce mechanical breakage and fallout — particularly relevant during seasons when lashes are repeatedly curled, coated in mascara, and removed with cleansers in cold, dry air. Stronger existing hairs mean the lash line looks denser even before the growth cycle delivers new fullness.

Results follow a predictable timeline: improved condition (less breakage, shinier hairs) within 2–4 weeks; visible fullness improvements at 6–8 weeks; and maximum results at approximately 12 weeks of consistent nightly use. As with all follicle-conditioning serums, results are maintained through continued use — stopping application allows lashes and brows to return to their natural baseline over time.

How to Use

Apply nightly to clean, dry lash lines and brows using the precision applicator. Consistent daily use for 6–8 weeks is needed before visible results. Continue use to maintain results — stopping allows lashes and brows to return to their natural state over time.

Frequently Asked Questions

How long does shipping take when I order the Nu Colour® Lash + Brow Serum in Canada?

Orders ship from the official Nu Skin Canada warehouse and typically arrive within 3–7 business days across most of Canada. Remote communities in Northern Ontario, Northern BC, Yukon, Nunavut, and the NWT may require additional transit time. Standard shipping is CA$2.99, with free shipping on orders over CA$79.

How long before I see fuller-looking lashes and brows?

Most users notice improved lash condition — less breakage, shinier hairs — within 2–4 weeks of consistent nightly use. Visible fullness improvements typically emerge at the 6–8 week mark, with maximum results around 12 weeks. The growth cycle cannot be rushed; nightly consistency is the key variable.

Is the serum safe for contact lens wearers?

Apply to the outer lash line, not the waterline. Allow the serum to dry fully before inserting contact lenses. Most contact lens wearers tolerate the serum without issue; if any irritation develops, discontinue use and consult a healthcare professional.

Does this serum contain prostaglandins or prescription-only ingredients?

No. The Nu Colour® Lash + Brow Serum is a cosmetic product formulated with peptides and conditioning agents — not prostaglandin analogues such as bimatoprost, which require a prescription in Canada and are associated with potential side effects including iris pigmentation changes. This serum is available without a prescription and regulated as a cosmetic under Health Canada's Food and Drugs Act and Cosmetic Regulations.

Can I use this serum under eye makeup?

The serum is designed for nightly application after removing eye makeup and cleansing the face. Do not apply under mascara, eyeliner, or other eye products — apply it last in your evening routine to a clean, dry lash line and brow area. In the morning, allow it to fully absorb before applying makeup.

What happens if I stop using the serum?

Results are maintained through continued use. Once you stop regular nightly application, lashes and brows will gradually return to their natural baseline over time. This is consistent with how all follicle-conditioning serums function — they support the conditions for healthy growth during active use, rather than permanently altering the hair structure.

Can I use the Nu Colour® Lash + Brow Serum alongside other Nu Skin eye-area products?

Yes. The serum targets the lash line and brow area specifically; it is compatible with eye-area treatments applied to the surrounding skin, such as the ageLOC® LumiSpa® IdealEyes (CA$48.00). Apply the lash and brow serum last in your nightly routine, after other eye-area treatments have been absorbed.

Is it worth pairing with a lash-enhancing mascara during the day?

For Canadians who want maximum daytime impact during the 6–8 week conditioning period — particularly through the winter months when lashes look their sparsest — pairing the serum with the Nu Colour Curl & Lash Mascara (CA$23.00) provides both a daily cosmetic lift and an overnight conditioning treatment working in tandem.
