Lash curlers are underrated. A good one lifts lashes in seconds and makes mascara look significantly more dramatic. A bad one crimps (creating a sharp angle instead of a curve), pinches eyelid skin, or pulls lashes out. The difference comes down to the curler’s curve matching your eye shape, the pad quality, and the hinge mechanism.
After trying six curlers across different eye shapes, here’s what held up and what didn’t.
How We Evaluated
Each curler was used on three different eye shapes (standard almond, hooded, and monolid) over multiple sessions. We assessed:
- Curl quality: Smooth curve vs. harsh crimp
- Comfort: Pinching, pulling, or skin catching
- Coverage: Whether all lashes were reached, including corners
- Curl retention: How long the lift lasted with and without mascara
- Pad quality: Durability and ease of replacement
We sourced all products independently at retail prices. No brand sent us samples for this review.
Best Overall: Shiseido Eyelash Curler (~$22)
The Shiseido is the gold standard for most eye shapes, and its reputation is earned. The curved plate follows the natural arc of most almond and round eye shapes, the grip is firm without requiring excessive squeezing, and the resulting curl is smooth rather than a sharp crimp.
What we found: After curling, lashes held their lift for 8+ hours when followed with mascara. Without mascara, the curl softened to about 60% after 4 hours - still noticeable but less dramatic. Zero pinching across dozens of uses. The replacement pad fits precisely without slipping mid-curl, which is a common problem with cheaper curlers.
Where it falls short: The curve is slightly too deep for very flat lid shapes. On monolid testers, the outer corner lashes didn’t fully reach the pad, leaving them uncurled. If your eye shape is flat across the top, the Shu Uemura below fits better.
- Price: ~$22 on Amazon
- Best for: Standard almond and round eye shapes, first-time curler users
- Replacement pads: Available separately for ~$5
Best for Hooded and Monolid Eyes: Shu Uemura Eyelash Curler (~$25)
The Shu Uemura curler has a shallower, wider curve specifically designed for flatter eye shapes. Where standard curlers create a curve that doesn’t make full contact with a monolid, the Shu Uemura’s flatter plate sits flush against the entire lash line.
What we found: On testers with monolid and hooded eye shapes, the Shu Uemura lifted all lashes evenly - corners included - where the Shiseido left the outer 15-20% of lashes flat. The hinge is slightly stiffer than the Shiseido, which means you need a bit more hand strength, but the result is a more consistent curl across the full lash line.
Where it falls short: On deeply curved eye shapes, the flat plate misses the center lashes. This curler is specifically designed for flatter lid profiles.
- Price: ~$25 on Amazon
- Best for: Hooded eyes, monolid eyes, flat-across-the-top lid shapes
- Replacement pads: Available separately
Best Budget: e.l.f. Eyelash Curler (~$4)
At $4, the e.l.f. curler outperforms its price point significantly. The curve fits a range of eye shapes (it splits the difference between the Shiseido’s deep curve and the Shu Uemura’s flat design), the grip is comfortable, and replacement pads are included.
What we found: Results were slightly less dramatic than the Shiseido - the curl was good but not as lifted at the roots, and it softened faster (about 5-6 hours vs. 8+ with the Shiseido). The hinge felt slightly looser after several weeks of use, though it still functioned fine. For occasional use, as a travel backup, or for someone who wants to try lash curling without spending $22, it’s excellent.
Where it falls short: The pad material is slightly harder than the Shiseido or Shu Uemura pads, which means the curl is a bit less smooth. Serious curler users will notice the difference. Casual users probably won’t.
- Price: ~$4 on Amazon
- Best for: Budget buyers, first-time users, travel kits, occasional use
- Replacement pads: One included
Best Heated: Panasonic EH-SE70 (~$35)
Heated curlers use gentle warmth to set the curl - similar to how heat shapes hair. Instead of a clamp, the Panasonic uses a heated wand that you roll through lashes in sections. The heat molds lashes into a curved shape that holds significantly longer than a mechanical curl.
What we found: Curl lasted noticeably longer than any mechanical curler - still holding at full strength after 10 hours. The technique takes a few tries to learn (you’re rolling through sections of lashes rather than clamping all at once), but once you have the motion down, it’s fast. Especially effective for naturally straight lashes that won’t hold a mechanical curl at all.
Where it falls short: Requires AAA batteries. The heating element needs 30-60 seconds to warm up. The learning curve is real - your first 3-4 uses will produce uneven results until you figure out the angle and speed. Not ideal for people who want a one-squeeze solution.
- Price: ~$35 on Amazon
- Best for: Lashes that won’t hold a mechanical curl, straight Asian lash types, anyone who wants all-day curl without re-curling
How to Curl Lashes Without Damage
Lash curling is safe when done correctly. Damage happens from specific preventable mistakes:
- Curl before mascara, never after. Dried mascara makes lashes brittle and stiff. The curler clamp will snap or crimp them rather than creating a smooth bend
- Curl in three positions: Base of lashes (closest to the lid), mid-lash, and tips. One squeeze at each position for 10 seconds creates a smooth, natural-looking curve rather than a single sharp angle
- Use gentle, sustained pressure. A firm 10-second hold at each position is better than a hard squeeze. Squeezing too hard crimps rather than curls
- Replace pads every 3 months. Worn or nicked pads create uneven pressure and can catch individual lashes. Keep replacements on hand
- Check for metal-on-lash contact. If the rubber pad is missing, shifted, or worn through, stop immediately. Metal directly touching lashes will crease and damage them
- Clean the curler periodically. Mascara residue, oil, and skin cells build up on the pad and metal plates. Wipe with a damp cloth weekly

Which Curler Shape Fits Your Eyes?
The most common frustration with eyelash curlers is buying one that doesn’t match your eye’s curvature. Here’s how to figure out which shape you need:
Deep curve (Shiseido-style): Your eye has a noticeable curve from inner to outer corner. When you look straight in a mirror, you can see the full curve of your upper lid. Most almond and round eye shapes fit here.
Shallow/flat curve (Shu Uemura-style): Your upper lid is relatively flat across the top. Monolid and many hooded eye shapes fit here. If a standard curler only catches your center lashes and misses the corners, try a shallower curve.
If neither fits perfectly: The e.l.f. curler’s medium curve is a decent compromise. Alternatively, some people use the “sectional” technique - curling the inner third, center, and outer third of lashes separately rather than trying to catch all lashes in one clamp.

Frequently Asked Questions
Should I curl my lashes before or after mascara?
Always before. Curling after mascara is the fastest way to damage or break your lashes. Dried mascara makes lashes stiff and brittle - the curler clamp will crimp or snap them instead of creating a smooth curl. Curl bare, clean lashes first, then apply mascara to set the curl in place.
How often should I replace my eyelash curler pad?
Every 3 months with regular use, or immediately if you notice any nicks, tears, or flattening in the rubber pad. A worn pad can't distribute pressure evenly, which causes crimping (a sharp bend instead of a smooth curve) and increases the risk of pinching skin or pulling lashes. Most curlers come with 1-2 replacement pads, and refills are available separately for popular brands like Shiseido and Shu Uemura.
Why does my eyelash curler pinch my eyelid?
Pinching happens for three reasons: the curler's curve doesn't match your eye shape (too flat or too curved for your lid), you're positioning it too close to the base of your lashes where skin meets lash, or the pad is worn down and exposing metal. Try repositioning the curler slightly away from the lash base, and check that the rubber pad is flush with the metal clamp. If it still pinches, the curler shape might not fit your eye anatomy - try a different brand.
Do heated eyelash curlers damage lashes?
Heated curlers are safe when used at the correct temperature setting and not held against lashes for too long (5-10 seconds per section is sufficient). The heat is much lower than a hair curling iron. The main risk is using them on lashes that already have mascara on - heat + dried mascara can cause brittleness. Use heated curlers on bare lashes, then apply mascara after.
