The Waterproof Mascaras Worth Your Money This Summer

A waterproof label promises one thing: it’ll survive water contact. What it doesn’t promise is that it’ll survive an actual hot, humid, twelve-hour day — heat, sweat, and repeated touching test a formula very differently than a splash test does. Some waterproof mascaras hold their curl and stay smudge-free well past the claim on the label. Others start breaking down long before. Here’s what’s actually worth packing this summer, and why.

What Actually Makes a Waterproof Mascara Worth It

Not every waterproof formula is solving the same problem, which is why the “best” one depends on what’s actually breaking down for you.

Formulas built around silicone resins and flexible polymers tend to hold up best against heat and repeated touching, not just direct water contact. Brush design matters almost as much as formula — a brush that coats and separates in one pass reduces the reapplication and layering that causes clumping later in the day. And a genuinely waterproof formula still needs the right removal approach; one that won’t budge for sweat and pool water won’t budge easily for a washcloth either.

Best for Maximum Wear Time

For anyone who needs a formula to survive the longest, most demanding day — travel days, weddings, anything back-to-back — these two are built specifically around extended wear claims.

Yves Saint Laurent Lash Clash Waterproof Mascara

£32 LOOKFANTASTIC

The longest wear-time claim in this list at up to 48 hours, which matters less for a single day than it does for back-to-back wear without a full reapplication. The double conical brush delivers a lot of product in one stroke, so it’s easy to overdo the volume if you’re not building gradually. Iris florentina extract is included for a conditioning benefit, though the buildable formula is really the standout feature here.

Lancôme Lash Idôle Waterproof Mascara

£21 LOOKFANTASTIC

Rated for 24 hours of waterproof, smudge-resistant wear, with a 125-bristle wand designed to coat without clumping. It’s specifically formulated to be comfortable for sensitive eyes and safe for contact lens wearers, which isn’t a given with waterproof formulas generally. The gel emulsion base keeps the formula feeling lighter than the wear-time claim might suggest.

Best for Volume and Definition

If the goal is maximum lash impact rather than just longevity, these two prioritise volume and lift over a headline wear-time number.

Too Faced Better Than Sex Waterproof Mascara

£28 LOOKFANTASTIC

The hourglass-shaped brush is built to catch lashes at every angle, which is where most of the volume payoff comes from rather than the formula alone. Water-resistant polymers hold the lift and curl, while porcelain flower extract and omega oil keep lashes conditioned through repeated wear. Worth noting: this is water-resistant rather than positioned as an extreme-wear waterproof formula, so it suits humidity and light water exposure more than a full submersion day.

Maybelline Lash Sensational Sky High Waterproof Mascara

£12.99 LOOKFANTASTIC

The Flex Tower brush bends to reach lashes from root to tip, and the bamboo extract and fibre formula builds length without the stiff, weighed-down feel some volumising formulas leave behind. It’s allergy-tested and ophthalmologist-tested, and despite being waterproof, the formula is genuinely washable at the end of the day — a detail worth knowing given how many waterproof formulas make removal harder than it needs to be. At this price point, it’s the easiest one on this list to justify replacing regularly.

Best for Lash Conditioning and Versatility

These two solve a slightly different problem: nourishing lashes with repeated wear, or adapting an existing mascara to hold up better under heat.

Clinique High Impact High-Fi Full Volume Waterproof Mascara

£27 LOOKFANTASTIC

Rated for up to 12 hours of waterproof wear, with a fibre-infused formula that builds volume in buildable layers rather than one heavy coat. Coconut, argan, and moringa oils in the formula are there specifically to offset the drying effect some waterproof formulas have on lashes over time. The High-Def Wave brush is designed to curl and separate in the same motion, which cuts down on clumping without needing a separate lash comb.

By Terry Terrybly Waterproof Mascara

£32 LOOKFANTASTIC

The most versatile option here: it works as a standalone mascara, but it’s also formulated to be layered over a favourite non-waterproof mascara to add water resistance without switching formulas entirely. The gel base with silicone resins and flex-stretch polymers is built specifically to resist heat and humidity, not just direct water contact, which is the more relevant test for a hot summer day than a swim test would be.

Removing Waterproof Mascara Without Damaging Lashes

Waterproof formulas resist water by design, which means a standard water-based cleanser or wipe often isn’t enough to remove them without rubbing — the exact motion most likely to cause lash breakage over repeated use.

An oil-based remover breaks down the same silicone and polymer bonds that make these formulas water-resistant in the first place. Holding a soaked cotton pad against closed lashes for a few seconds before gently wiping tends to lift waterproof formula with far less friction than immediate rubbing. This matters more over a full summer of near-daily waterproof wear than for occasional use, since repeated harsh removal is one of the more overlooked contributors to lash thinning over time.
