Master the art of applying Trinny London's Lash2Brow serum with this step-by-step guide. Learn proper technique for lashes and brows to boost growth and thickness.
When it comes to lash and brow serums, how you apply them is just as important as what's inside the bottle. Trinny London's Lash2Brow is a targeted formula designed to nourish and support the natural growth cycle of your lashes and brows, but to unlock its full potential, you need the right technique. A rushed or incorrect application can reduce absorption, cause irritation, or even lead to less visible results over time.

Whether you're new to growth serums or looking to refine your routine, this guide walks you through every step—from prepping your skin to integrating the serum into your daily regimen. By following these expert tips, you'll give your lashes and brows the best possible chance to look fuller, thicker, and healthier.
Why Application Technique Matters for Lash2Brow
Lash2Brow is more than just a serum; it's a carefully formulated blend of peptides and conditioning agents that work best when applied consistently and correctly. The serum needs to reach the hair follicles at the base of your lashes and brows without being wiped away by makeup, oils, or improper handling. If you apply too much, the product may migrate into your eyes and cause discomfort. If you apply too little, you might not see the growth benefits you're hoping for.
A precise, gentle application ensures that every drop of Lash2Brow stays where it's needed most. This is especially important for the delicate eye area, where skin is thinner and more absorbent. By taking an extra minute to follow the right steps, you protect your skin and maximise the serum's effectiveness.
- Apply Lash2Brow to completely clean, dry skin—free of makeup, moisturiser, and oils.
- Use the precision applicator tip to draw a thin line along the upper lash line (like liquid eyeliner).
- For brows, apply small dots along the brow shape and blend with the tip or a clean spoolie.
Step-by-Step: Lash2Brow Application for Lashes
Start with a clean slate. Remove all eye makeup, contact lenses (if you wear them), and wash your face with a gentle cleanser. Pat the eye area dry; any residual water or cream can dilute the serum and reduce absorption. Wait a few minutes to ensure the skin is completely dry before opening Lash2Brow.
Hold the wand horizontally and gently sweep it along the base of your upper lashes, similar to how you would apply a liquid eyeliner. Use one thin stroke per eye—no need to go over the same area twice. The formula is concentrated, so a little goes a long way. Avoid getting the product into your eyes; if you do, rinse immediately with cool water. Let the serum dry for about 30–60 seconds before applying any other eye products.
- Always apply Lash2Brow at the same time each day—ideally at night, as part of your evening skincare routine.
- Never pump the applicator in and out of the tube; it introduces air and bacteria. Twist the cap gently to dispense a tiny amount.
Step-by-Step: Lash2Brow Application for Brows
Brows are often neglected in serum routines, yet they play a huge role in framing your face. Lash2Brow works wonderfully on brows too. After cleansing and drying your face, use the same applicator tip to place small dots along the natural shape of each brow—focus on areas where you want more density, such as the arch or tail.
Once the dots are in place, use a clean spoolie or the side of the applicator to gently spread the product across the brow hairs, making sure it reaches the skin underneath. Do not rub or press hard. Let the serum absorb for a minute before applying any brow makeup or going to sleep. For best results, keep your brows free of powder or pencil in the area where you apply Lash2Brow.
- If you use brow gels or pomades, apply Lash2Brow first, wait 60 seconds, then add your usual brow products.
- Consistency is key—use Lash2Brow twice daily (morning and night) for at least 8–12 weeks to see visible improvement.
Integrating Lash2Brow into Your Skincare Routine
To make Lash2Brow a habit, pair it with another step you already do. Many Trinny London fans apply it right after using Take Back Time Elixir, a smoothing concentrate that preps the eye area without interfering with the serum. Simply apply your eye concentrate, let it sink in for a minute, then follow with Lash2Brow on the lash line and brows. This layering method keeps both products effective.

If you prefer a minimal routine, apply Lash2Brow as the final step before your moisturiser or night cream—just ensure no other products sit on top of the serum immediately. For daytime use, wait until the serum is fully dry before applying sunscreen or foundation around the eyes. A consistent routine with Lash2Brow, combined with a gentle cleansing and moisturising regimen, gives you the best chance of seeing fuller lashes and brows over time.
- Avoid using oil-based makeup removers on the eye area right before applying Lash2Brow—oil can block absorption.
- Store your Lash2Brow upright in a cool, dry place to keep the formula stable.
Common Mistakes to Avoid When Using Lash2Brow
One of the most frequent errors is applying too much product. A single stroke along the lash line or a few dots on the brow is enough. Overloading can lead to product migrating into the eyes, causing stinging or redness. Another mistake is inconsistent application—skipping days or applying only once daily when the instructions recommend twice daily can delay results.
Also, avoid sharing your Lash2Brow tube with others. The applicator tip touches your skin and lashes, and sharing increases the risk of bacterial transfer. Finally, don't expect overnight transformation. Growth serums work with your hair's natural cycle; noticeable changes typically appear after 8 to 12 weeks of regular use. Patience and consistent technique are your best allies.
- Do not apply Lash2Brow on broken or irritated skin—give any cuts or inflammation time to heal first.
- Always replace the cap tightly after use to prevent the formula from drying out.
Mastering the correct application of Lash2Brow is the key to unlocking its full growth potential for both lashes and brows. By following a clean, consistent routine and avoiding common pitfalls, you give your natural hairs the best environment to thrive. If you haven't yet added Lash2Brow to your daily regimen, now is the perfect time to start—explore this targeted serum and pair it with your favourite Trinny London products for a complete skincare and beauty ritual.
