Few things are more frustrating than spending time perfecting your lashes, only to glance in the mirror hours later and find mascara smudged under your eyes. Whether it’s caused by humidity, watery eyes or oily skin, smudging is a common concern. The good news is that with a few simple tweaks to your routine, it’s completely avoidable.

We thought we’d shine some light on why smudged mascara happens and share our top secrets to helping your mascara stay put all day, while still keeping your lashes lifted, defined and naturally beautiful.

Why Does Mascara Smudge Under My Eyes?

• Natural Oils - The skin around the eyes produces oil throughout the day, and depending on how oily your skin is, you may be more prone to mascara coming into contact with these oils and breaking down, causing mascara smudging.
• Watery or Sensitive Eyes - If your eyes water easily, traditional mascaras can dissolve or run, leading to smudging.
• Incorrect Application - Applying too much product, layering too quickly or coating the lashes unevenly can cause mascara to stay wet for longer, increasing the chance of transfer.
• Bottom Lashes - Bottom lashes sit closer to the skin and move more when you blink. This makes them one of the biggest contributors to under-eye smudging.
• Formula Choice - Some mascaras simply aren’t designed for long wear. If smudging is a constant issue, switching to a Tubing Mascara can make all the difference.

1. Setting Spray Before Applying Mascara

If you’re wondering how to prevent mascara from smudging under eyes, this step is a great place to start. Applying a light mist of setting spray before mascara helps lock in your base makeup and control oil around the eye area.

Finish your complexion first, lightly mist your face and allow it to fully dry before moving on to mascara. This creates a smoother, more stable surface, helping your mascara last longer without transferring.

2. Lash Primer Before Applying Mascara

Using an eyelash primer can make a noticeable difference if smudging is a regular issue. Primer coats and separates each lash, helping mascara grip to the lashes instead of the skin.

An eyelash primer also improves control during application, which is especially helpful if you’re learning how to apply mascara properly or struggle with clumping. Less movement, less smudging.

3. Use a Tubing Mascara

If you’ve ever asked yourself, ‘what is tubing mascara?’ this could be the solution you’ve been missing.
Tubing mascara works by wrapping each lash in tiny, flexible tubes rather than coating them with traditional pigment. These tubes don’t smudge, flake or run throughout the day, making them ideal for oily lids or watery eyes.
For anyone searching for a reliable tubing mascara UK option, look no further than the UKLASH Tubing Mascara. Tubing formulas are known for their long wear and easy removal. They stay put all day, then gently slide off with warm water. No rubbing, no panda eyes, and you can continue to grow your natural lashes with an award-winning serum whilst minimising damage.
Using Tubing Mascara is one of the most effective ways to stop mascara from smudging altogether.

4. Apply Mascara Properly

A big part of how to stop mascara from smudging comes down to technique. So it’s essential to know how to apply mascara properly
Start by removing excess product from the wand. Then, gently wiggle the brush at the base of the lashes before sweeping upwards. This ensures even coverage without overloading the lashes.
Try to avoid applying mascara to the backside of your top lashes, as this can leave excess product sitting close to the lid and increase the chance of transfer throughout the day. Keeping product focused on the front of the lashes helps maintain lift and definition without smudging.
Apply thin layers and allow each coat to dry slightly before adding another. If you’ve ever wondered how to apply mascara? the answer is slower, lighter and more controlled than you might think.

5. Skip The Bottom Lashes

When it comes to how to keep mascara from smudging under eyes, skipping bottom lashes can be surprisingly effective. Because bottom lashes sit so close to the skin, mascara here is far more likely to transfer throughout the day.
If you want definition, use a very light hand or a tubing mascara designed for precision. Otherwise, leaving bottom lashes bare can instantly reduce smudging while keeping your look clean and lifted.

Smudge-free lashes aren’t about doing less, they’re about doing things smarter. From understanding how long mascara can last on your lashes, to learning how to apply mascara properly and choosing a Tubing Mascara, small changes can make a big difference.

At UKLASH, we believe beauty should work with you, not against you. With the right routine, you can finally stop mascara from smudging and enjoy lashes that stay flawless from morning to night.
