How does it work?

Nu Skin Lash and Brow Serum works by utilizing a powerful blend of ingredients that target the needs of your lashes and brows. The serum’s active ingredients work together to nourish and strengthen your hair follicles.

When you apply the serum, it penetrates the hair follicles and stimulates the production of keratin, a protein crucial for hair strength and thickness. Peptides in the serum send signals to the hair follicles, promoting growth and resulting in denser, longer lashes and bolder brows.

The serum also contains extracts like Larch Wood and Camellia Sinensis Leaf Extracts, which provide essential nutrients and antioxidants to protect the lashes and brows from damage and keep them healthy. Clover Sprout Extract stimulates hair follicles, increasing hair density for more abundant brows and lashes.

With consistent use of Nu Skin Lash and Brow Serum, you can expect visible improvements in the length, thickness, and overall appearance of your lashes and brows. It’s a comprehensive solution that enhances your natural beauty and helps you achieve captivating lashes and bold brows.

My Review after 4 weeks

I’ve been using Nu Colour Lash and Brow Serum for the past four weeks, and I must say that I’m impressed with the results I’ve seen so far. The most noticeable improvement has been in the length of my lashes. They appear longer and more defined

One of the things I love about this product is how simple it is to use. I just apply a thin layer of the serum at the root of my lashes and brows, both morning and evening. The application process is quick, fitting seamlessly into my daily beauty routine. I appreciate that I can easily incorporate it into my makeup routine by applying mascara after the serum. It doesn’t interfere with my regular makeup application.

What’s great is that I can also leave the serum on overnight for added nourishment and benefits. It’s incredibly convenient, especially for those nights when I’m too tired to follow an extensive skincare routine. Additionally, if you’re someone who wears lash extensions, you can still use this serum to maintain the health and appearance of your natural lashes.

Overall, I find Nu Skin Lash and Brow Serum to be an amazing product. Its effectiveness in enhancing lash length, its simplicity of use, and its compatibility with other beauty routines make it a standout choice. I’m excited to continue using this serum and see even more improvements in the coming weeks.

Nu Colour Lash and Brow Serum has a combination of key ingredients that work synergistically to deliver remarkable results. Let’s dive deeper into each ingredient and understand their specific contributions:


  • Biotinoyl Tripeptide-1: Biotinoyl Tripeptide-1 is a peptide known for its ability to enhance the appearance of eyelashes. This peptide stimulates the production of keratin, a protein that strengthens and nourishes the lashes. By promoting keratin synthesis, Biotinoyl Tripeptide-1 helps improve the thickness, length, and strength of your lashes, resulting in a fuller and more luscious lash appearance.
  • Acetyl Tetrapeptide-3: Acetyl Tetrapeptide-3 is a peptide known for its benefits in hair care. It helps strengthen the hair follicles, promoting healthier and more resilient lashes and brows. This peptide also helps improve hair thickness and density, contributing to the overall fullness and volume of your lashes and brows.
  • Myristoyl Pentapeptide-17: Myristoyl Pentapeptide-17 is a peptide that plays a significant role in enhancing the thickness, density, and length of eyelashes. By stimulating the production of keratinocytes, which are cells responsible for lash growth, Myristoyl Pentapeptide-17 helps your lashes appear thicker, denser, and longer over time. This peptide is instrumental in achieving a more dramatic and captivating lash look.

Natural Ingredients:

  • Larch Wood Extract: Larch Wood Extract is derived from the wood of the Larch tree and is known for its hair-enhancing properties. It contains plant polysaccharides that help improve hair density and provide nourishment to the hair follicles. By supporting the overall health of the lashes and brows, Larch Wood Extract contributes to their strength, thickness, and appearance.
  • Camellia Sinensis Leaf Extract: Camellia Sinensis Leaf Extract is derived from green tea and is rich in antioxidants. It helps protect the lashes and brows from damage caused by free radicals, which can lead to brittle and weakened hairs. The antioxidants in Camellia Sinensis Leaf Extract nourish the lashes and brows, promoting their overall health and vitality.
  • Clover Sprout Extract: Clover Sprout Extract is a natural ingredient known for its ability to increase hair density and strengthen hair. By providing essential nutrients to the hair follicles, this extract helps improve the fullness and thickness of both lashes and brows, giving them a more abundant and luscious appearance. Clover Sprout Extract is instrumental in achieving a visibly fuller look.

It contains bioactive compounds and essential nutrients that promote stronger, thicker, and fuller-looking hair. Red Clover helps prevent breakage, supports healthy hair growth, and contributes to the overall appearance of lashes and brows.

Conditioning Ingredients:

  • Panthenol: Panthenol, also known as provitamin B5, is a conditioning agent that helps improve the moisture content of the lashes and brows. It enhances their flexibility and softness while providing a protective barrier against environmental stressors. Panthenol helps keep the lashes and brows hydrated and nourished, promoting their overall health and vitality.
  • Sodium Hyaluronate: Sodium Hyaluronate is a form of hyaluronic acid known for its excellent moisturizing properties. It helps retain moisture in the lashes and brows, keeping them hydrated and preventing dryness. Sodium Hyaluronate contributes to the smoothness and suppleness of the lashes and brows, enhancing their appearance and promoting healthier growth.
  • Amino Acids: Amino acids are the building blocks of proteins and play a crucial role in hair health. They help strengthen the lashes and brows, improve their elasticity, and promote healthy growth. Amino acids provide essential nutrients to the hair follicles, supporting their overall nourishment and contributing to the vitality of the lashes and brows.
  • Oat Extract: Oat Extract is a conditioning ingredient known for its soothing and nourishing properties. It helps calm and moisturize the lashes and brows, relieving any dryness or irritation. Oat Extract supports the overall health and condition of the lashes and brows, ensuring they remain in their optimal state.
