I’ve been getting this mascara from Olive Young since 2018. Every time a Western friend visits Seoul and asks me to take them shopping, they end up buying this one — sometimes two.
In the US, it’s called the ETUDE Curl Fix Mascara. In Korea, we call it the 래쉬펌 (Lash Perm). That name isn’t just marketing — it tells you exactly what this mascara is engineered to do: hold the curl of an actual lash perm salon treatment, all day, in the kind of heat and humidity that Seoul summers deliver without apology.
I tested this for 3 months. Monolid eyes, oily T-zone, Seoul summer. Here’s what I actually think.
Quick Verdict: ETUDE Curl Fix (Lash Perm) Mascara
|
What I Love
• Curl holds 12+ hours in 80%+ humidity |
Things to Know
• Waterproof = oil cleanser required to remove |
| Buy This If | Skip This If |
|---|---|
| Monolid or hooded eyes that lose curl fast | You want intense volume and drama |
| Oily lids / humid climates / long event days | You skip oil cleanser in your routine |
| “My lashes but lifted” natural finish | You prefer fiber or tubing formula mascaras |
Why “Lash Perm”? The Seoul Context Most Reviews Miss
In Seoul, lash perms are a regular beauty appointment. Salons charge ₩30,000–₩60,000 ($22–$45) to semi-permanently curl your lashes using a mild chemical process — similar to a hair perm, but scaled for individual lashes. The effect lasts 4–6 weeks, and in 2024–2025, lash perm appointments became one of the most-booked treatments at Korean beauty salons, especially among office workers who wanted the “just woke up with perfect lashes” look without daily effort.
When ETUDE launched this mascara, they specifically named it 래쉬펌 because that’s the beauty benchmark every Korean woman already understands. Not “curling mascara.” Lash perm. The implication: this formula is engineered to produce salon-quality curl retention in a $12 tube.
That naming decision also tells you who this product was built for: Korean women with monolid eyes and oily skin, living in a climate where summer humidity regularly exceeds 80% and where the standard Western mascara droops by noon. Seoul summers are genuinely brutal for eye makeup. The Han River district in August feels like breathing through a wet towel. If a mascara survives that environment on monolid lashes, it’ll hold up anywhere.
ETUDE Curl Fix Mascara on Monolid Eyes: Does It Actually 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: 7 AM to 11 PM 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.
7:00 AM — Application. Two coats, square brush pressed at root, upward stroke, held 2 seconds at the tip. No lash curler. My lashes lifted noticeably. The formula dried in about 90 seconds; I could feel the polymer “set” — lashes felt rigid, held in the curled position.
9:30 AM — Subway commute. Hongik University station. Packed car, AC barely keeping up. I checked in my phone camera — curl intact, no transfer to my upper lid. The thing about Seoul subway in summer is that you’re basically standing with your face six inches from a stranger’s shoulder for thirty minutes straight. It’s not a test you plan for, but it’s real.
2:00 PM — Office, air conditioning all morning. The switch from outdoor 33°C to indoor 20°C is its own form of stress on makeup. Dry AC air plus the ambient office humidity. Checked at the bathroom mirror: still holding. Slight softening at the curl tip — not drooping, just the peak of the curve slightly less aggressive than morning. For 7 hours in, this was better than I expected.
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.
11:00 PM — Home, bathroom mirror. 16 hours after application. The curl had softened maybe 20% from morning — lashes were still pointing upward, not their natural downward position. Removal with cleansing oil took about 45 seconds of gentle massage. No lash loss, no irritation. Clean.
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 actually 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 | 12–16 hrs in humidity | 10–14 hrs in humidity |
| 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 | ~$12–14 | ~$12–16 |
| Best For | Monolid, root-lift priority | Defined separation, minimal look |
My verdict: If your main goal is maximum curl retention on monolid eyes, ETUDE wins. The square brush is more effective at catching lashes from the root on a flat eyelid surface. Heroine Make is slightly better if you want ultra-clean separation with a more minimalist finish. They’re both excellent — but 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 — at least 10 minutes. Residual oil on the lashline breaks waterproof adhesion.
- Press the flat square edge at the root, not mid-lash. The square geometry is doing the work here — don’t waste it by starting halfway up.
- Pull straight upward, toward the ceiling, not outward. Hold at the tip for 2–3 seconds. You’ll feel the formula setting.
- 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’s exactly what keeps the curl intact for 12+ hours. The same polymer structure that resists humidity resists water. You need an oil-based cleanser: apply, massage 30–45 seconds, rinse. If you double-cleanse already (which you should with any waterproof formula), this is zero extra effort.
“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’s a realistic daily goal, and ETUDE Curl Fix hits it reliably. Eight years of Koreans agreeing isn’t an accident.

FAQ
Is ETUDE Curl Fix the same as the Lash Perm Mascara?
Yes — same formula, different name for Western markets. In Korea it’s sold as 래쉬펌 (Lash Perm). The product inside is identical.
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 literally 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, for root curl lift. Heroine Make for separation. If curl retention is the priority — ETUDE wins on monolid anatomy.
