Essential Tools and Products for Application

Before you begin, gather all the necessary tools to ensure a smooth application process. You'll need a pair of tweezers (preferably flat-tipped for precision), a mirror with good lighting, and a clean, dry surface to work on. The most crucial element is the adhesive. For underlash extensions, a specialized glue is recommended to ensure a secure yet gentle hold. The DUO Over & Under Glue Liner in Clear is a fantastic option, as it provides a strong bond while being safe for the delicate under-eye area.

Additionally, consider using a lash applicator or a clean mascara wand to help place the extensions precisely. Some users find it helpful to have a magnifying mirror to see the fine details. If you're new to underlash application, practice on a flat surface first to get comfortable with the placement technique. Once you have everything ready, you're set to begin.

Step-by-Step Application Guide

Start by ensuring your lower lash line is clean and free of any makeup or oils. Use a gentle cleanser or a makeup remover to prep the area, then pat dry. This step is crucial for the adhesive to bond effectively. If you have oily skin, consider using a primer or a light dusting of translucent powder to absorb excess oil, which can interfere with the glue's staying power.

Next, remove one extension from the tray using your tweezers. Hold it near the base, being careful not to touch the band with your fingers, as oils from your skin can weaken the adhesive. Apply a thin, even layer of the DUO Over & Under Glue Liner along the band. Wait a few seconds for the glue to become tacky—this ensures a stronger hold and prevents slipping.

Now, position the extension under your natural lower lashes, as close to the lash line as possible. Use your tweezers to gently press the band against your skin, holding for a few seconds to allow the adhesive to set. Repeat this process for each section, working from the outer corner toward the inner corner. For a seamless look, trim the extensions to fit your eye shape if necessary.

  • Always apply glue to the band, not directly to your skin
  • Wait for the glue to become tacky before placing the extension
  • Press firmly but gently to ensure the band adheres well

Pro Tips for a Flawless Finish

To achieve a truly professional result, consider layering your underlash extensions with your favorite mascara. Apply a light coat of mascara to your lower lashes first, then place the extensions on top. This creates a fuller, more defined look while ensuring the extensions blend seamlessly with your natural lashes. However, be mindful not to overdo it, as too much mascara can weigh down the extensions and cause them to droop.

Another pro tip is to use a lash curler on your lower lashes before application. This lifts the natural lashes slightly, making it easier to place the extensions and ensuring they sit at the perfect angle. Additionally, if you find the extensions are too long, you can trim them from the outer edge to match your eye shape. Always cut in small increments to avoid removing too much.

Finally, practice makes perfect. Don't be discouraged if your first attempt isn't flawless. Underlash application requires a steady hand and patience. With time, you'll develop your own rhythm and technique, resulting in beautiful, natural-looking extensions every time.

  • Layer with mascara for added volume and definition
  • Use a lash curler to lift natural lashes for easier placement
  • Trim extensions carefully to fit your eye shape

How to Remove and Reuse Your Underlash Extensions

Removing your underlash extensions is just as important as applying them. To avoid damaging your natural lashes, always use a dedicated remover. The DUO Underlash Bond Remover is specially formulated to dissolve the adhesive gently, allowing you to remove the extensions without pulling or tugging. Apply a small amount to the band, wait a few seconds, and then carefully slide the extension off.

Once removed, clean the extensions with a gentle makeup remover to eliminate any leftover glue or mascara. Store them in their original tray to maintain their shape. With proper care, your Dear Seamless Underlash Extensions can be reused multiple times, making them a sustainable and cost-effective choice for your beauty routine.

  • Always use a dedicated remover to protect natural lashes
  • Clean extensions after each use to prolong their lifespan
  • Store in the original tray to maintain shape
