Longer-looking lashes do not always come from the biggest brush. A slim wand can separate and stretch each lash, while a denser formula creates the thickness that makes eyes look fuller.
That tradeoff matters in this roundup of the best mascaras for long thick lashes. You will find washable and waterproof formulas, buildable volume, fiber-style effects, and different black shades, so keep reading to compare the details that shape the final look.
Key Takeaways
- Choose a buildable formula if you want to layer length and volume without creating heavy, clumpy lashes.
- Pick a slim, flexible brush for better separation, especially if your lashes are short or sparse.
- Select waterproof mascara for humid weather, long days, or curl that needs extra hold.
- Compare washable formulas if easy removal and gentler everyday wear matter most.
- Check the shade and lash effect, since blackest black adds drama while defining formulas create a cleaner finish.

4D Silk Fiber Mascara Waterproof
If you want length and volume from one mascara, this 4D silk fiber formula is a strong match. The waterproof design, smudge-resistant wear, and fuller-looking finish suit long days, humid weather, and anyone who prefers a more dramatic lash line.
Its main limitation is the waterproof formula, which can be less forgiving during removal than a washable option. Use an oil-based eye makeup remover and take your time around the lashes.

- Shade:Black

Maybelline Sky High Very Black
Maybelline’s washable Sky High formula fits anyone who likes customizable intensity instead of one fixed finish. You can build toward more length, volume, curl, and definition, while the Very Black shade keeps the look noticeable without requiring a separate lash primer.
The washable base is convenient for everyday removal, but it may not hold up as well as a waterproof mascara through heavy humidity or watery eyes. Choose this version for flexible daily wear rather than maximum resistance.
- Brand:Maybelline
- Formula:Washable
- Shade:Very Black
- Lash Effect:Volumizing and lengthening
- Count:1
- Additional Feature:Curling effect
- Additional Feature:Multiplying lash look
- Additional Feature:Easy daily removal
-
Maybelline Sky High Blackest Black
Choose this Sky High version when deep pigment matters as much as length. The Blackest Black shade pairs with a buildable formula, giving you room to create a softer daytime look or a more intense finish with additional coats.
Because it is washable, removal stays simple, but staying power is not its strongest suit in wet conditions. This version makes the most sense for anyone who wants Sky High’s flexible lash effects with a darker color payoff.
- Brand:Maybelline
- Formula:Washable
- Shade:Blackest Black
- Lash Effect:Lengthening and defining
- Count:1
- Additional Feature:Volumizing effect
- Additional Feature:Curling effect
- Additional Feature:Multiplying lash look

Revlon So Fierce Big Bad Lash
Revlon So Fierce! Big Bad Lash suits a bold, high-impact eye look, especially if you prefer a blackest-black shade. Its larger lash-focused positioning makes it a natural pick for makeup routines built around dramatic definition rather than a barely-there finish.
The available details do not specify whether the formula is washable or waterproof, so you should not expect a clearly defined wear profile from the product title alone. Its 0.34-fluid-ounce size is also worth noting if you prefer a standard-size mascara tube.
- Brand:Revlon
- Shade:Blackest Black
- Size:0.34 fl oz
- Count:1
- Additional Feature:So Fierce! collection
- Additional Feature:Big lash positioning
- Additional Feature:Dark eye definition

4D Silk Fiber Mascara Two-Pack
This two-pack works well if you want fiber-style length and thickness with a spare tube ready to go. The waterproof formula targets long-lasting, smudge-resistant wear, while the title also highlights lifting, curling, and a very black finish.
Waterproof mascara can take more effort to remove, and the fiber effect may look more dramatic than some everyday makeup routines call for. The two-tube format is practical, but the product may be more than you need if you rarely wear mascara.
- Brand:4D Silk Fiber
- Formula:Waterproof
- Shade:Very Black
- Lash Effect:Lengthening and thickening
- Count:2
- Additional Feature:Primer brush included
- Additional Feature:Multiplying lash effect

Maybelline Falsies Lash Lift Blackest
Maybelline The Falsies Lash Lift is aimed at anyone who wants visible lift and curl without switching to a waterproof formula. Its washable base combines volume, length, and multiplication, making it a useful choice for fuller-looking lashes in a daily makeup routine.
The Blackest Black shade gives the look extra intensity, though washable formulas generally offer less resistance to moisture than waterproof versions. If easy removal matters more than maximum wear, this formula has a sensible balance.
- Brand:Maybelline
- Formula:Washable
- Shade:Blackest Black
- Lash Effect:Volumizing and lengthening
- Count:1
- Additional Feature:Curling effect
- Additional Feature:Multiplying lash look

L’Oréal Telescopic Blackest Black
For a defined, separated lash line, L’Oréal Paris Telescopic is the clear fit in this group. The formula focuses on length and separation, so it suits you if thick, clumpy volume is less appealing than a cleaner, more elongated look.
Its washable formula makes removal straightforward, but it may not provide the same moisture resistance as a waterproof mascara. The 0.27-fluid-ounce size is compact, which works well for a streamlined makeup bag.
- Brand:L’Oréal Paris
- Formula:Washable
- Shade:Blackest Black
- Lash Effect:Separating and lengthening
- Size:0.27 fl oz
- Count:1
- Additional Feature:Volume effect

4D Silk Fiber Mascara Black
This 4D Silk Fiber mascara is suited to you if thicker, longer lashes are the main goal. Its waterproof black formula is positioned to create full-looking, curled lashes, making it a natural choice for a more noticeable eye look.
The waterproof design should appeal to anyone who prioritizes lasting wear, but removal may require more care than with a washable formula. The title does not specify a tube count or exact size, so the available details are limited there.
- Brand:4D Silk Fiber
- Formula:Waterproof
- Shade:Black
- Lash Effect:Volume and length
- Additional Feature:Fiber-based formula
- Additional Feature:Full lash appearance
- Additional Feature:Long-lasting wear

Maybelline Falsies Lash Lift Very Black
The Very Black version of The Falsies Lash Lift fits everyday makeup looks that need lift, curl, and fuller-looking lashes without a waterproof formula. Its combination of lengthening and volumizing effects gives you a more noticeable result while keeping the routine simple.
The lighter shade name separates it from the Blackest Black version, though both share the same general lash-focused concept. Since it is washable, it is easier to remove, but it may need more protection from moisture during long or humid days.
- Brand:Maybelline
- Formula:Washable
- Shade:Very Black
- Lash Effect:Volumizing and lengthening
- Count:1
- Additional Feature:Multiplying lash effect
- Additional Feature:Falsies-style finish

4D Silk Fiber Mascara Two-Pack
This two-pack is aimed at creating an extension-style appearance with a waterproof, smudge-proof finish. The title specifically highlights no clumping, along with length, thickness, curl, and all-day fullness, so it suits you if you want drama without a visibly lumpy lash line.
As with most waterproof fiber formulas, removal can take more time and a dedicated eye makeup remover. The two-pack is convenient for keeping a backup, although the available details do not identify the exact shade name or tube size.
- Brand:4D Silk Fiber
- Formula:Waterproof
- Lash Effect:Lengthening and thickening
- Count:2
- Additional Feature:Smudge-proof finish

Frequently Asked Questions
How Do I Make My Lashes Look Both Longer And Thicker?
Start with clean, dry lashes and curl them before applying mascara. Place the first coat at the roots, wiggle the brush slightly, then pull upward through the lengths. Add a second, thinner coat while the first is still slightly tacky. Focus extra product near the roots for fullness, but use the brush tip to separate the ends so length does not turn into clumps.
Is Waterproof Mascara Better For Holding A Curl?
Waterproof formulas often hold a curl better because they contain less water and dry with a firmer finish. They can be helpful for straight or downward-pointing lashes, as well as humid weather. The tradeoff is removal. Use an oil-based or dual-phase eye makeup remover, let it sit for several seconds, and wipe gently rather than scrubbing.
How Can I Prevent Clumps?
Wipe excess formula from the wand opening before application, especially after pulling out the brush. Apply thin coats, combing from root to tip with a clean spoolie if lashes begin sticking together. Do not keep layering once the mascara has dried completely. That often creates flakes and stiff, spidery lashes, which is a dramatic look, just not always the intended one.
What Mascara Is Best For Sensitive Eyes?
Choose a fragrance-free formula labeled for sensitive eyes, and check whether the brand lists ophthalmologist testing or contact-lens compatibility. Tubing mascaras may also suit some sensitive eyes because they can be removed with warm water instead of heavy rubbing. Stop using mascara if you notice burning, swelling, persistent redness, or unusual watering. Replace the product after an eye infection, even if the tube still looks perfectly innocent.
How Often Should I Replace Mascara?
Replace mascara about every 3 months, since the tube collects air and bacteria each time you use the wand. Replace it sooner if the formula smells different, becomes dry or flaky, or causes irritation. Write the opening date on the tube with a small label or marker. That simple reminder can save you from guessing later, because mascara packaging rarely announces its retirement with much ceremony.
