Nu Colour Lash + Brow Serum (Ireland/EU)

For Irish Winters When Lashes Take a Battering — and Brows You've Over-Tweezed Since Your Twenties

If you're a Dubliner who wears heavy eye makeup through the long dark months, or someone in Cork or Galway whose brows never quite recovered from the pencil-thin trend of the 2000s, the Nu Colour Lash + Brow Serum (€48.00) is a once-nightly conditioning treatment built around peptides and biotin. It doesn't artificially extend the hair growth phase like prescription-only prostaglandin drugs — it nourishes the lashes and brows you're already growing, supporting stronger, thicker, healthier-looking hairs over an 8-week cycle. One applicator, used along the upper lash line and through the brows each evening before bed.

Best suited for: Sparse or thinning lashes from extension use, mascara wear, or natural ageing; over-plucked brows in recovery; anyone whose lashes break easily in dry indoor-heated environments during Irish winter
Less suited for: Anyone seeking a medically licensed growth treatment; those with active eye infections or recent eye surgery
Pairs well with: Nu Colour Curling Mascara – Black (€28.00) for daytime wear; ageLOC LumiSpa iO IdealEyes Brightening Eye Cream (€48.00) for the under-eye area alongside the lash line

What's Inside the Formula

The Nu Colour Lash + Brow Serum combines three conditioning actives that work on the structure of the hair itself — not a topical film that just coats the surface.

Peptide Complex

Peptides are short chains of amino acids. Applied topically at the lash and brow root, they condition the follicle environment and support the structural integrity of each growing hair. The result is lashes that emerge looking thicker and are less prone to mid-length breakage — particularly relevant in Ireland's indoor-heated winter air, which can leave fine hairs brittle and dry.

Biotin (Vitamin B7)

Biotin is essential for the synthesis of keratin — the structural protein that hair, including lashes and brows, is made from. Topical biotin application supports the keratin scaffold of each lash hair, contributing to improved resilience and a fuller appearance over time. Biotin is well-established in hair care formulation as a keratin-supporting ingredient.

Panthenol (Provitamin B5)

Panthenol penetrates the hair shaft and binds moisture, improving flexibility and reducing brittleness. For lashes that have been compromised by lash glue, extension removal, or daily waterproof mascara use, panthenol supports structural repair and reduces breakage at the tip — where lashes most visibly snap.

How It Works vs Prescription Growth Treatments

It's important to understand the distinction: this is a cosmetic serum regulated under EU Cosmetics Regulation (EC) No 1223/2009, not a medicinal product. Prescription lash treatments such as bimatoprost (a prostaglandin analogue) work by pharmacologically extending the hair growth phase and are licensed for medical use — but come with side effects including potential iris pigmentation changes. The Nu Colour Lash + Brow Serum carries none of those risks. It improves lash condition and appearance through nourishment, not pharmacological action. If you have questions about prescription lash treatments, consult your GP or ophthalmologist.

Clinical Assessment

In Nu Skin's internal clinical assessment, participants reported visibly improved lash appearance after 8 weeks of consistent daily use. As with all cosmetic clinical assessments commissioned or conducted by the manufacturer, individual results may vary. Results are not guaranteed and depend on consistency of use, starting lash condition, and individual biology.

How to Use

Apply once daily, at night, to clean lashes and brows. Using the precision applicator, swipe along the upper lash line in a thin line (similar to applying eyeliner) and brush lightly through the brow hairs. Allow to dry fully before sleeping. Use consistently for a minimum of 8 weeks — lash growth cycles run 3–4 months, so improvements accumulate gradually. Once dry, the formula can remain on overnight and you can apply mascara over the lashes the following morning.

Contact lens wearers: remove lenses before applying and allow the serum to dry completely before reinserting.

Revive Active Beauty Complex is an oral supplement and works via a different mechanism to topical lash serums — the two approaches are not directly comparable.

Frequently Asked Questions

Is the Nu Colour Lash + Brow Serum available in Ireland, and how long does delivery take?

Yes — the serum ships to all addresses in the Republic of Ireland and Northern Ireland from Nu Skin's EU warehouse. Delivery typically takes 3–5 business days. No customs duties or import charges apply, as products ship from within the EU single market. Free delivery is available on orders over €100.

How long before I see visible results?

Most users notice improved lash condition — reduced breakage, better flexibility — within 4 weeks of consistent nightly use. Visible improvements in thickness and fullness typically appear between 6–8 weeks. For the most complete results, continue use through a full 12-week lash cycle. Results depend on starting lash condition and consistency of use.

Can I use this serum after having lash extensions removed?

Yes, and this is one of the most common use cases. Lash extensions — particularly removal of the adhesive — can leave natural lashes weakened, sparse, and brittle. The peptide and biotin formula is designed to support recovery of compromised natural lashes over the 8–12 week period following removal.

Is it safe for contact lens wearers?

The formula is ophthalmologist-tested. Contact lens wearers should remove lenses before applying and allow the serum to dry completely before reinserting. If you experience any eye irritation, redness, or discomfort, discontinue use and consult your optician or GP.

Will it change my eye colour like some prescription lash treatments?

No. Iris pigmentation changes are associated with prostaglandin analogue drugs (such as bimatoprost) — prescription-only medicinal products that work pharmacologically. The Nu Colour Lash + Brow Serum is a cosmetic product under EU Cosmetics Regulation (EC) No 1223/2009. It contains no prostaglandins and does not affect iris colour.

Can I apply mascara over it the next morning?

Yes. Apply the serum at night and allow it to dry before sleep. The following morning, once dry, you can apply mascara as normal. The serum's conditioning effect continues to work through the lash cycle regardless of daytime makeup use, as long as you apply it consistently each evening.

Is this suitable for someone with sensitive skin around the eye area?

A patch test is recommended before first use for anyone with sensitive skin. Apply a small amount to the inner wrist and wait 24 hours before proceeding with eye area use. If you have a history of contact dermatitis, eczema, or eye sensitivity, consult your GP or dermatologist before use. The formula contains panthenol, which is generally well-tolerated, and no known common allergens — but individual sensitivity varies.
