Nu Colour Lash + Brow Serum (UK)

Nu Colour Lash + Brow Serum: Clinically Proven Growth Serum for Thicker Lashes and Brows

Nu Colour Lash + Brow Serum is a peptide-powered growth serum that strengthens, nourishes, and visibly enhances the appearance of lashes and brows. In Nu Skin's clinical study, participants showed thicker, longer-looking lashes within 4 weeks of daily use, with continued improvement through 12 weeks. The serum uses red clover extract and an amino acid blend to support the hair growth cycle — working at the follicle level rather than just coating existing hairs for a temporary thickening effect.

If your lashes have thinned from years of mascara, lash curlers, or extensions — or if your brows never recovered from the over-plucking era — this serum provides a genuine growth-support treatment rather than a cosmetic cover-up.

What Sets Nu Colour Lash + Brow Serum Apart

Most lash serums on the UK market use either prostaglandin analogues (which can cause iris colour changes and orbital fat loss with prolonged use) or simple conditioning oils that don't influence actual growth. Nu Colour's formula takes a middle path: peptides and plant extracts that support the natural growth cycle without the side effects associated with prostaglandin-based products.

The dual-ended applicator — fine tip for lashes, broader brush for brows — means one product handles both areas. It's oil-free, which is important for anyone with lash extensions (oil-based serums dissolve lash extension adhesive). The formula is also ophthalmologist-tested for safety around the delicate eye area.

Key Ingredients

Red Clover Extract: Contains biochanin A, an isoflavone that supports the hair growth phase (anagen) and helps reduce premature hair shedding. Extends the natural growth cycle so lashes and brows grow longer before falling out.

Amino Acid Blend: Provides the protein building blocks that lash and brow hairs need during the growth phase. Supports stronger, more resilient hair formation.

Peptide Complex: Strengthens the hair follicle and conditions existing hairs, reducing brittleness and breakage.

How to Get the Most from Lash + Brow Serum

Apply once daily — ideally in the evening after removing all makeup and cleansing the eye area. Use the fine-tip applicator along the upper lash line (like you'd apply liquid eyeliner) and the broader brush through the brows. You don't need to coat every individual lash; the serum absorbs into the skin at the base of the lashes where the follicles are.

Consistency is everything. The lash growth cycle is approximately 4–8 weeks, so daily application for a minimum of 4 weeks is needed before you'll see visible results. Most users report the most noticeable improvement between weeks 8–12. After reaching your desired results, reduce to 3–4 times per week for maintenance.

Avoid applying to the lower lash line — the serum can migrate into the eye during sleep, and the lower lashes don't need direct application (they benefit from incidental transfer from the upper line).

Frequently Asked Questions

How quickly can I get the Lash + Brow Serum delivered in the UK?

We ship from the official Nu Skin UK warehouse. Standard delivery typically arrives within 3–5 working days across the UK.

Is this safe for lash extensions?

Yes. The oil-free formula won't dissolve lash extension adhesive. Many users apply it between extension appointments to strengthen their natural lashes underneath.

Can this change my eye colour?

No. Unlike prostaglandin-based lash serums (such as products containing bimatoprost), Nu Colour's peptide and plant-based formula does not carry this risk. It's a different class of active ingredient entirely.

How long does a tube last?

With daily use on both lashes and brows, approximately 8–10 weeks — which aligns neatly with the timeframe needed to see full results.
