Product Overview

Nu Colour® Lash + Brow Serum is a targeted cosmetic serum formulated to improve the visible appearance of eyelashes and eyebrows. Positioned within Nu Skin's colour and eye-care category, it addresses common concerns including sparse, brittle, or weakened lashes and brows. The formula is lightweight, non-irritating, and free from parabens, silicone, phthalates, alcohol, dyes, fragrance, oil, and prostaglandin. It has been ophthalmologist tested and is suitable for contact lens wearers. Visible transformation is reported in as little as four weeks, with continued improvement over longer use. The bottle and cap are made from 100% plant fibre polymer (PFP), reflecting a commitment to sustainable packaging. Ships from the official Nu Skin warehouse through local NuBest stores worldwide.

Key Ingredients & Science

The serum's efficacy is anchored by a multi-peptide and botanical complex:

• Acetyl Tetrapeptide-3 — A biomimetic peptide that supports the anchoring proteins of the hair follicle, helping reinforce lash and brow density at the root.
• Biotinoyl Tripeptide-1 — Combines biotin with a peptide chain to strengthen the keratin infrastructure of the hair fibre, reducing brittleness.
• Myristoyl Pentapeptide-17 — A lipopeptide shown to upregulate keratin gene expression, supporting visibly longer, fuller lashes.
• Clover & Clover/Mung Bean Sprout Extracts (Trifolium Pratense / Vigna Radiata) — Phytoestrogenic isoflavone sources that help extend the anagen (growth) phase of follicle cycling.
• Panthenol & Sodium Hyaluronate — Classic humectants that condition and hydrate individual hair fibres and the surrounding skin.
• Larix Europaea Wood Extract & Camellia Sinensis Leaf Extract — Antioxidant-rich botanicals that help protect follicles from oxidative stress.

The formulation also includes an amino acid complex (glycine, arginine, serine, histidine, and others) to provide the building-block nutrition keratin synthesis requires.

How to Use

After cleansing and thoroughly drying the application area, apply a thin layer of serum to the root of your eyebrows and along the root of both the upper and lower lash line. Use daily, morning and evening, for best results. Consistent daily application over a minimum of four weeks is recommended to observe visible improvement.

Frequently Asked Questions

What is Nu Colour® Lash + Brow Serum?

Nu Colour® Lash + Brow Serum is a dual-purpose, peptide-infused cosmetic serum designed to visibly strengthen, nourish, and enhance the appearance of both eyelashes and eyebrows. It is ophthalmologist tested, prostaglandin-free, and suitable for daily use by contact lens wearers.

What are the key active ingredients in Nu Colour® Lash + Brow Serum?

The primary actives are three synergistic peptides — Acetyl Tetrapeptide-3, Biotinoyl Tripeptide-1, and Myristoyl Pentapeptide-17 — supported by clover and mung bean sprout isoflavone extracts, panthenol, sodium hyaluronate, and a broad amino acid complex to nourish follicles and reinforce keratin structure.

How does Nu Colour® Lash + Brow Serum work?

The peptide complex acts at the follicle level: Biotinoyl Tripeptide-1 and Acetyl Tetrapeptide-3 reinforce hair anchoring proteins and keratin infrastructure, while Myristoyl Pentapeptide-17 upregulates keratin gene expression. Botanical isoflavones help extend the hair growth phase, and humectants condition each fibre, collectively producing visibly longer, thicker, and less brittle lashes and brows.

What results can I expect and in what timeframe?

Clinical and consumer evaluations referenced by Nu Skin indicate visible improvements in lash and brow fullness, length, and shine in as little as four weeks of twice-daily use. More significant results — including reduced brittleness and a healthier overall appearance — are reported with continued longer-term application.
