Define Tubing Mascara

Define Tubing Mascara wraps and separates each lash in a lightweight polymer veil for longer-looking definition without heaviness or clumps. The water-resistant tubes release with warm water and gentle pressure, without the need for scrubbing or tugging.

Regular price £19.00 Sale price £14.25

Polished definition for lashes that look finer, shorter or less defined than they used to.

Define Tubing Mascara coats each lash individually in a lightweight, flexible tube, creating a clean and separated finish without heaviness or clumps.

One coat gives refined everyday definition. Apply a second coat while the formula is still wet for greater intensity.

At the end of the day, warm water softens the tubes so they slide away with gentle pressure—without heavy remover, scrubbing or tugging at the lash line.

Designed for everyday elegance, it gives lashes a refined, lifted appearance without the need for harsh removal. At the end of the day, simply soak lashes with warm water and use gentle pressure to slide the tubes away — no scrubbing, tugging, or heavy remover required.

Ideal for customers who want a polished lash look that feels modern, low-maintenance, and kinder to the delicate eye area.

Film-forming polymers create a flexible, water-resistant tube around each lash. Once set, the formula stays in place during wear. Warm water softens the tubes, allowing them to release cleanly with gentle pressure.

Apply to clean, dry lashes. Curl lashes first, if desired.

Sweep the brush from root to tip, using a gentle side-to-side motion to separate and define. Apply a second coat while the formula is still wet for greater intensity.

Allow the mascara to set before touching the lashes.

Soak lashes with warm water using your fingertips, a soft cloth or a damp cotton pad. Hold for several seconds, then use gentle downward pressure to slide the tubes away.

Do not scrub or pull at the lash line.

Define Tubing Mascara is water-resistant, not waterproof. Its flexible tubes are designed to stay in place during wear and release with warm water and gentle pressure.

Yes. Apply mascara to clean, dry lashes. Use your lash serum separately after cleansing, once the lash line is completely clean and dry.

What customers notice

"A Natural Everyday Favourite"

Line Theory Define Tubing Mascara has been a wonderful discovery. It feels lightweight on my lashes and remains comfortable throughout the day, without the dry or stiff sensation I’ve experienced with other formulas.

The brush allows me to coat even the smaller lashes around the inner corners, and I can build the product gradually. One coat gives me subtle definition, while two coats create a longer and more noticeable look without becoming clumpy.

I’m especially pleased with how reliable it is during long days. Even when my eyes water, the mascara doesn’t seem to spread around my eye area or create the usual dark marks beneath my lashes. The removal process is also much gentler than I expected: warm water loosens the formula, allowing it to slide away without needing an oily remover.

“I Look Glamorous In Seconds!”

Line Theory Define Tubing Mascara gives my lashes the kind of precise, elegant definition I usually struggle to achieve. The formula coats each lash individually, making them appear darker and longer while still keeping them separated.

I like that I can control the final effect depending on the occasion: a light application looks refined and understated, while an additional coat adds enough impact for an evening look. It doesn’t overwhelm my lashes or make them look stuck together, and the finish remains flattering from every angle.

“My lashes look great”

I’ve been using Line Theory Define Tubing Mascara as my everyday mascara, and I’m genuinely impressed by how polished it makes my lashes look. The formula gives them noticeable length and definition without creating an overly heavy or dramatic effect.

It separates my lashes nicely, even when I apply a second coat, and the finished result looks clean, soft and natural. It’s ideal for workdays or minimal-makeup looks because it enhances my eyes without making it obvious that I’m wearing a lot of product.

“Beautiful lashes and zero hassle!”

What has made this mascara stand out for me is how well it wears throughout the day. I usually experience some smudging beneath my eyes after several hours, but this stays looking neat and doesn’t leave me constantly checking the mirror.

At night, it comes away easily with warm water and gentle pressure, so I don’t need to scrub at the delicate skin around my eyes. It has made both applying and removing mascara feel much simpler, and I would happily buy it again.
