Mascara That Doesn't Clump: What Clumping Is and How to Avoid It
By COVERGIRL Team
What is mascara clumping?
Mascara clumping is when wet mascara glues several lashes together into thick bundles, so lashes look spiky or matted instead of fanned out. Clumps can also appear as small beads of product sitting on the lash tips.
Clumping matters because it works against what most people want from mascara. Lashes stuck together read as fewer, heavier lashes rather than fuller ones, and definition between individual lashes disappears.
What causes mascara to clump?
Mascara clumps when there is more product on the lashes than the brush can spread evenly, or when fresh product meets product that has started to dry. The most common causes are:
- Too much product on the brush. An overloaded wand deposits excess formula that pools between lashes.Which mascaras don't clump?
- Layering over a dried coat. Adding a new coat after the first one has set drags and glues lashes together.
- Pumping the wand. Pushing the brush in and out of the tube can push air in and thicken the formula.
- An old or dried-out tube. Mascara thickens over time, which makes it harder to apply in a thin, even layer.
- A brush that loads but doesn't comb. Brushes that only deposit product, without bristles that separate, leave lashes stuck together.
Which mascaras don't clump?
The mascaras least likely to clump are those designed with a brush that separates lashes while it applies product. Two COVERGIRL Lash Blast mascaras are built specifically around clump-free results: Lash Blast Showstopper Mascara and Lash Blast Clump Crusher Mascara.
COVERGIRL Lash Blast Showstopper Mascara
COVERGIRL Lash Blast Showstopper Mascara is an extreme-volume mascara designed for a false-lash look with clump-free definition. Its exclusive Double Act™ brush twists fiber and molded bristles together 360° to build volume and thickness while defining each lash.
The formula delivers up to an 800% volume boost (vs. bare lashes) and stays clump-free, flake-free and transfer-proof all day. It is infused with a Volume Conditioning Complex of peptide, castor oil and vitamin B5, and it is formulated without parabens, sulfates, phthalates and mineral oil.
Lash Blast Showstopper Mascara comes in four shades: 800 Hypnotic Black, 805 Spotlight Brown, 815 Black Plum and 820 Hypnotic Black Waterproof.
COVERGIRL Lash Blast Clump Crusher Mascara
COVERGIRL Lash Blast Clump Crusher Mascara is a volumizing mascara built around separation. Its double-sided, curved brush has a lash-loading section that saturates lashes with product and fine-tooth comb bristles that spread it evenly. A straight bristle edge follows the curve of the eye for root-to-tip coverage.
How does mascara brush design prevent clumps?
Brush design prevents clumps by controlling how much product reaches the lashes and by combing lashes apart as it coats them. Our brushes do this in different ways:
| Lash Blast Showstopper | Lash Blast Clump Crusher | |
| Brush name | Double Act™ dual-material brush | Double-sided curved brush |
| Bristles | Fiber and molded bristles, twisted 360° | Lash-loading section plus fine- tooth comb bristles |
| How it fights clumps | Two bristle types build volume while defining lashes | Comb bristles distribute product evenly and keep lashes separated |
| Volume approach | Buildable, layer by layer, up to 800% (vs. bare lashes) | Volume in each stroke |
Fiber bristles hold and deposit formula, while molded bristles are firmer and help separate. A brush that combines both, like the Double Act™ brush, is designed to add bulk without gluing lashes together.
Which clump-free mascara is right for you?
The right clump-free mascara depends on the finish you want: bold, false-lash volume or soft, separated definition. Use this guide:
| Mascara | Best for | Not ideal for |
| Lash Blast Showstopper, 800 Hypnotic Blac | Bold, buildable, false-lash volume with definition | A barely-there, natural look |
| Lash Blast Showstopper, 805 Spotlight Brown | Volume with a softer color than black | The deepest, most dramatic contrast |
| Lash Blast Showstopper, 815 Black Plum | Volume with a hint of color | A classic black look |
| Lash Blast Showstopper Waterproof, 820 Hypnotic Black | Waterproof wear with the same brush and volume | Quick removal with a regular cleanser |
| Lash Blast Clump Crusher | Separated, defined lashes with volume in each stroke | Building to an extreme false-lash finish |
How do you apply mascara without clumps?
To apply mascara without clumps, start at the base of the lashes, move the brush from root to tip, and build coats gradually. Follow these steps:
- Remove excess product. Wipe the brush lightly on the tube opening so it isn't overloaded.
- Start at the root. Place the brush at the base of the lashes.
- Wiggle from root to tip. Move the brush side to side as you pull it through the lashes.
- Twist and rotate the brush. Turning the brush as you apply helps coat every lash and builds volume.
- Layer to build. Add coats until you reach the volume you want. Apply each coat before the last one sets.
Common mascara mistakes that cause clumps
Most clumps come from technique, not the mascara itself. Avoid these habits:
- Coating only the tips. Starting at the tips leaves product sitting on the ends, where it beads.
- Waiting too long between coats. A new layer over a dried one drags lashes together.
- Pumping the wand. Pull the brush straight out instead.
- Keeping mascara too long. An old tube is thicker and harder to apply evenly.
- Rushing the root. Skipping the wiggle at the base means product isn't spread through the lashes.
