Nu Colour Lash + Brow Serum (Ireland/EU)

Nu Colour Lash + Brow Serum: Nourish Sparse Lashes and Brows

Nu Colour Lash + Brow Serum is a conditioning treatment that nourishes lashes and brows to help them appear thicker, fuller, and healthier-looking over time. The formula contains a blend of peptides and biotin that support the keratin structure of lash and brow hairs. In Nu Skin's clinical assessment, participants noticed visibly improved lash appearance after 8 weeks of daily use. If your lashes are sparse, thin, or have been damaged by extensions, heavy makeup, or over-tweezing, this serum is designed to support recovery.

How Does a Lash Serum Work?

Lashes and brows are hair — they grow in cycles, with each individual hair lasting 3–4 months before falling out and being replaced. Lash serums work by nourishing the hair during its growth phase, supporting stronger, thicker lashes that are less prone to breakage. The peptide complex in this serum conditions the lash root, while biotin supports keratin production (the protein that hair is made of).

It's not a growth drug — it doesn't extend the growth phase like prescription products (such as bimatoprost). What it does is improve the condition and appearance of the lashes you're already growing, making them look fuller, healthier, and more resilient.

Key Ingredients

• Peptide complex: Conditions and nourishes hair follicles at the lash and brow line — supports stronger, thicker-looking growth
• Biotin (vitamin B7): Essential for keratin production — strengthens the structural protein of lash and brow hairs
• Panthenol (provitamin B5): Adds moisture and flexibility, reducing brittleness and breakage

How to Use

Apply once daily, at night, to clean lashes and brows. The serum comes with a precision applicator — swipe along the upper lash line (like a thin eyeliner) and brush through the brows. Allow to dry before sleeping. Use consistently for at least 8 weeks before judging results — lash growth cycles mean it takes time for the full effect to become visible. Can be used under mascara the following morning once dry.

Frequently Asked Questions

Do you deliver to Ireland?

Yes. We deliver throughout the Republic of Ireland and Northern Ireland from the official Nu Skin EU warehouse. Standard delivery is 3–5 business days. Free delivery on orders over €100.

How long before I see results?

Most people notice improvement in lash condition (less breakage, improved flexibility) within 4 weeks. Visible changes in thickness and fullness typically appear around 6–8 weeks. Full results at 12 weeks with consistent use.

Is it safe for contact lens wearers?

Apply with lenses removed and allow the serum to dry completely before reinserting. The formula is ophthalmologist-tested, but if you experience any eye irritation, discontinue use and consult your optician or GP.

Can I use it after lash extensions are removed?

Yes — it's particularly useful for this purpose. Lash extensions (and their removal) often leave natural lashes weakened and sparse. The peptide and biotin formula supports recovery of the natural lashes.

Does it change eye colour?

No. Unlike some prescription lash treatments (prostaglandin analogues), this cosmetic serum does not affect iris pigmentation. It's a conditioning treatment, not a growth hormone.
