This ETUDE Curl Fix mascara review is for anyone whose lashes look lifted in the bathroom mirror, then quietly give up by lunch. ETUDE Curl Fix, also sold as Lash Perm Mascara, is the Korean mascara I reach for when I want curl hold without the heavy, crunchy lash look. I tested it through Seoul humidity, subway commutes, dinner smoke, and long makeup days.
If you are comparing curl-hold options before buying, I also made a best Korean mascaras on Amazon for straight lashes guide with Etude, Clio, rom&nd, and lower-lash picks.
Quick context: I have stick-straight Asian lashes that resist every curler I have tried, and most Western mascaras give me 3 hours of curl before everything goes flat. The ETUDE Curl Fix is the third Korean curl-locking mascara I have committed to long-term, and the only one I have re-bought twice.
I first bought this at Olive Young years ago because the brush looked weird in a useful way. It was not the prettiest mascara on the shelf. It looked practical. Every time a friend visits Seoul and asks for a mascara that can handle straight lashes, this is one of the first tubes I show them.
In the US, it is usually listed as the ETUDE Curl Fix Mascara. In Korea, it is tied to the idea of lash perm makeup: a lifted, clean lash shape that looks awake without adding a thick mascara wall. That context matters because this is not a fluffy volume mascara. It is a curl-hold mascara first.
I tested this for 3 months. Monolid eyes, oily T-zone, Seoul summer. Here's what I think.

Why "Lash Perm"? The Seoul Context Most Reviews Miss
In Seoul, lash perms are a regular beauty appointment. The appeal is simple: lashes look lifted before mascara, before coffee, before you have enough patience to do anything complicated. A lash perm is still a salon service, though, and it is not something everyone wants to repeat every month. Curl Fix sits in that daily middle ground: not a salon result, but a quick lifted-lash effect that fits a normal morning.
That is why the lash-perm idea makes sense here. The promise is not "bigger lashes." It is "your lashes stay up." If your lashes are already long but point downward, that distinction matters.
It also tells you who this product was built for: people with straight lashes, monolid or hooded eyes, and makeup that tends to smudge when the weather gets sticky. Seoul summers are rough on eye makeup. The Han River district in August feels like breathing through a wet towel. If a mascara can stay neat in that setting, I start paying attention.
ETUDE Curl Fix Mascara on Monolid Eyes: Does It Work?
This is what the product was specifically built to answer, and it's the part most Western reviews gloss over.
Monolid eyes - common among Korean and other East Asian women - have a flat eyelid surface with no crease visible. This creates two specific mascara problems: first, there's less surface area for the wand to grab, so lashes lie flat instead of curling outward. Second, the lash line is closer to the brow, which means mascara smudges transfer easily to the skin above and below.
The ETUDE square brush is designed specifically for this anatomy. The flat horizontal edge creates a platform that catches lashes from directly beneath the root - not from the side the way round brushes do - and drags them straight upward. That upward motion, held for 2-3 seconds while the formula sets, creates a curl that works with monolid geometry instead of against it.
I've also noticed that this mascara handles oily lids better than most. My T-zone runs oily - by midday in summer, there's a slight sheen on my nose and forehead. Most mascaras that smudge on me fail because of lid oil transferring. The film-forming polymer in Curl Fix bonds to the lash surface dry and doesn't re-emulsify with skin oil the same way standard formulas do. That's the technical reason it doesn't panda on oily eyelid skin.

My Full-Day Test in Seoul
I ran this as a real wear test on a weekday in late July - the kind of Seoul day where the air is thick enough to taste.
Morning application. Two coats, square brush pressed at the root, upward stroke, short pause at the tip. No lash curler. My lashes lifted noticeably. The formula dried fast enough that I had to work one eye at a time, and once it set, the lashes felt locked in place.
Subway commute. Hongik University station, packed car, air conditioning barely keeping up. I checked in my phone camera after I got out. Curl was still visible, and there was no transfer to my upper lid. The thing about Seoul subway in summer is that you are standing close to everyone for long enough that your makeup either behaves or tells on you.
Office check. The switch from outdoor heat to dry indoor air can make makeup look tired in a different way. Bathroom mirror check: still holding. The curl was softer than the morning, but it had not collapsed into my natural downward lash shape.
8:30 PM - Korean BBQ with friends. A 고깃집 in Mapo-gu. Charcoal grill, visible smoke, the kind of evening where you leave smelling like samgyeopsal and honestly don't care. I held a compact mirror over the grill steam to check - this is the actual stress test I use for waterproof mascara. Curl still there. Zero panda. My friend asked what mascara I was wearing mid-dinner, which is the highest endorsement I can give.
Night removal. By the time I got home, the curl was not fresh-morning sharp, but my lashes were still lifted. Removal with cleansing oil was easy once I let the oil sit and massage through the lashes. No rubbing, no tugging, no lash panic.
That's the full picture. Not a lab test. A Seoul weekday in July.
ETUDE Curl Fix vs Heroine Make Long & Curl Mascara: Honest Comparison
This is the comparison people search for - and I've tested both side by side.
Heroine Make (Japanese brand, very popular on r/AsianBeauty) has a loyal following for similar reasons: waterproof, curl-focused, designed for straight East Asian lashes. So which one wins?
| ETUDE Curl Fix | Heroine Make Long & Curl | |
|---|---|---|
| Curl Hold | Long-wear curl hold in humid weather | Strong curl hold with cleaner separation |
| Brush Shape | Square edge (root-lift focused) | Thin curved (separation focused) |
| Volume | Light-medium | Light (very natural) |
| Smudge on Oily Lids | Excellent | Very good |
| Removal Ease | Needs oil cleanser | Needs oil cleanser |
| Price | Usually budget-friendly online | Usually budget-friendly online |
| Best For | Monolid, root-lift priority | Defined separation, minimal look |
My verdict: If your main goal is curl lift on monolid eyes, I would start with ETUDE. The square brush is easier for me to press at the root on a flatter eyelid shape. Heroine Make is better if you want cleaner separation with a softer finish. They solve slightly different problems.
ETUDE Curl Fix vs Clio Kill Lash Superproof: K-Beauty Showdown
Both are K-beauty waterproof mascaras, both designed for Korean lash types, both available on Amazon. The difference is intent.
Clio Kill Lash is a volume-first mascara with strong hold. ETUDE Curl Fix is a curl-first mascara with strong hold. If you want your lashes to look thicker and more dramatic, Clio. If you want your lashes to look lifted and defined without adding bulk, ETUDE.
I switch between them depending on the occasion. Daily office look: ETUDE. Night out or event: Clio. Both live in my mascara drawer right now.
How to Apply ETUDE Curl Fix for Maximum Curl (Korean Technique)
- Start with dry lids. Let your eye cream and sunscreen fully absorb before mascara. Residual oil on the lashline weakens waterproof adhesion.
- Press the flat square edge at the root, not mid-lash. The square geometry is doing the work here, so starting halfway up wastes the best part of the brush.
- Pull straight upward, toward the ceiling, not outward. Pause briefly at the tip while the formula starts to set.
- First coat: root to tip. Second coat: tips only. This adds length without clumping at the base.
- Optional curler: If you want maximum lift, use your curler before applying, and curl again while the mascara is still wet - it bonds the curve into the formula as it dries.
The Common Complaints: Addressed
"It smudged under my eyes after a few hours."
Almost certainly a residual oil issue, not a product failure. Waterproof formula bonds to dry surfaces. If you applied moisturizer or eye cream and didn't let it fully absorb, the formula can't adhere properly. Let skincare sink in fully before application.
"It's really hard to remove."
Yes, and that is part of why the curl stays in place. The same film that resists humidity also resists water. Use an oil-based cleanser, massage gently, then rinse. If you already double-cleanse after waterproof makeup, it fits into that routine.
"Did it cause lash fallout?"
The formula itself isn't causing fallout - rubbing dry is. Applying the oil cleanser and letting it work, rather than scrubbing, prevents lash loss. The mascara removes cleanly when you give the oil time to break it down.
Is ETUDE Curl Fix Mascara Worth It?
For monolid eyes, oily lids, and humid environments: yes, without hesitation. This is what it was built for, and it delivers consistently.
For double-lidded eyes in a dry climate: still good, but the performance gap between this and a standard drugstore curling mascara will be smaller. You might not feel the difference as much.
What keeps me buying this is simple: on mornings I skip the lash curler, my eyes still look awake. Not dramatically made-up, just lifted and defined. That is the kind of daily mascara result I care about.
FAQ
Is ETUDE Curl Fix the same as the Lash Perm Mascara?
Yes. It is the same product idea with different naming across markets. If the listing says ETUDE Curl Fix or Lash Perm Mascara, check the shade and seller before buying.
Can I use this without a lash curler?
Yes. The square brush and film-forming formula are designed to curl as you apply. Most Korean users skip the curler with this mascara. If you have very stubborn lashes, curl first and apply while lashes are still bent.
Does it work on monolid eyes?
It was designed for monolid eyes. The square brush geometry lifts lashes upward on a flat lid surface where round brushes tend to miss the root. This is its strongest use case.
How do I remove it properly?
Oil-based cleanser first. Apply, massage gently for 30-45 seconds, rinse. Do not rub dry - that's what causes lash fallout. Follow with a gentle foam cleanser.
Is the Amazon 1+1 set the same formula as the Korean version?
Yes. Same formula, same mascara. The packaging is in English for international markets.
ETUDE Curl Fix vs Heroine Make - which is better for monolid eyes?
ETUDE is my pick for root curl lift. Heroine Make is my pick for cleaner separation. If curl retention is the priority, I would start with ETUDE.
