After a consultation about thin, sparse lashes that drop heavy extensions quickly, the stylist mixed flat-lash C-curl extensions in 9 and 10mm, and the service was comfortable enough to fall asleep during, with no stinging or gritty feeling. The finished lashes defined the eyes without eyeliner and cut morning prep time by more than 15 minutes. ## Good to know - **Address**: 5th floor, 21 Olympic-ro 12-gil, Songpa-gu, Seoul - **Location**: 7-minute walk from Exit 2, Jamsilsaenae Station; 5th floor of the building with Baekeok Coffee - **Hours**: Mon–Fri 11:00–21:00, Sat 11:00–17:00 - **Reservations**: Reservations available; pets welcome - **Parking**: No dedicated lot; nearby paid public parking available - **Service received**: Flat-lash extensions, C-curl, 9–10mm mix - **Other services**: Lash lift, eyebrow tattoo, lip tattoo, lash growth serum for sale *as written by the visitor on Sep 14, 2026* If you get eyelash extensions regularly, you'll know the struggle — finding a salon that both suits your eye shape and actually lasts is basically finding a needle in a haystack. My lashes are thin and sparse, so extensions would fall out or my eyes would get tired not long after, and I'd been wandering from salon to salon like a lash nomad. This time I finally settled at Rose Lash, known around Jamsil for doing great lash extensions, so here's my review :) Let me share how the natural flat-lash extensions turned out! ![Before and after comparison of flat-lash eyelash extensions](https://img.superchart.com/images/jamsil-flat-lash-extension-rose-lash/jamsil-flat-lash-extension-rose-lash-01-4wtnp-m-1200.webp) *before & after* ## Rose Lash location and hours: 7 minutes from Jamsilsaenae Station ![Rose Lash location and hours information](https://img.superchart.com/images/jamsil-flat-lash-extension-rose-lash/jamsil-flat-lash-extension-rose-lash-02-11j70-900.webp) 📍Address: 21 Olympic-ro 12-gil, Songpa-gu, Seoul, South Korea ⏰Hours: Mon–Fri 11:00–21:00, Sat 11:00–17:00 ✔️Reservations available, pets welcome Rose Lash is a 7-minute walk from Exit 2 of Jamsilsaenae Station.

I came for extensions, but this place is also known as a go-to spot for lash lifts, haha. ![Sign showing eyebrow tattoo and lip tattoo services](https://img.superchart.com/images/jamsil-flat-lash-extension-rose-lash/jamsil-flat-lash-extension-rose-lash-12-1vte4-m-900.webp) They also do eyebrow tattoos and lip tattoos, so keep that in mind if you visit :) ![Lash serums displayed behind the counter](https://img.superchart.com/images/jamsil-flat-lash-extension-rose-lash/jamsil-flat-lash-extension-rose-lash-13-2ee0z-900.webp) Behind the counter they also sell various lash serums. ## Why Rose Lash recommended flat lashes for thin, sparse lashes ![Seating where the pre-treatment consultation took place](https://img.superchart.com/images/jamsil-flat-lash-extension-rose-lash/jamsil-flat-lash-extension-rose-lash-14-1sa2j-900.webp) Before the treatment began, I had a detailed one-on-one consultation with the director. She carefully checked my natural lash condition, eye shape, usual makeup style, and even the mood I wanted. ![Reference materials showing lash types and curl options](https://img.superchart.com/images/jamsil-flat-lash-extension-rose-lash/jamsil-flat-lash-extension-rose-lash-15-10yjv-966.webp) I told her I usually like a natural yet defined look, but that my lashes are weak, so heavy extensions tend to droop or fall out quickly ㅠㅠ. She studied my eyes carefully and strongly recommended flat lashes! Flat lashes are great for anyone who wants natural but defined eyes :) I could feel her pride and expertise throughout the consultation, which made me trust her completely with my eyes, haha. ## Is flat-lash extension comfortable? Stinging and gritty feeling ![Treatment bed prepared with a blanket for lash extensions](https://img.superchart.com/images/jamsil-flat-lash-extension-rose-lash/jamsil-flat-lash-extension-rose-lash-16-hhqc9-900.webp) The moment I lay on the bed and got covered with a blanket, the warm, cozy feeling made my eyes close on their own, haha. Once the extension work started, I could immediately tell how delicate her touch was. At salons with less skill, you often get stinging eyes from the glue smell or discomfort from the tugging on your lashes, right? But with the director at Rose Lash, I had zero stinging or foreign-body feeling the entire time. Her touch was so gentle that I ended up falling into a deep sleep partway through, haha. ![Flat, sparse lashes before extensions](https://img.superchart.com/images/jamsil-flat-lash-extension-rose-lash/jamsil-flat-lash-extension-rose-lash-17-5dkmo-m-900.webp) Can you see my flat, before clam-eyes..^^ This is how they looked before... ![Defined eyes right after flat-lash extensions](https://img.superchart.com/images/jamsil-flat-lash-extension-rose-lash/jamsil-flat-lash-extension-rose-lash-18-102sn-m-509.webp) And this is how they turned out!!!!!! Genuinely doll-like eyes..🥺🤍 The moment I looked in the mirror after the treatment, I let out an involuntary gasp ㅠㅠ My flat, weak lashes were now lifted up beautifully, with every single strand perfectly groomed! ![Lengthened outer corners from the C-curl 9–10mm mix](https://img.superchart.com/images/jamsil-flat-lash-extension-rose-lash/jamsil-flat-lash-extension-rose-lash-19-4741p-823.webp) The clear look of the C-curl made my eyes look so much brighter and more open, and with the 9–10mm mixed in nicely, the lashes got naturally longer toward the outer corners, making my eyes look much longer too — I loved that effect so much, haha. But what I was most satisfied with was the natural definition. I love it so much ㅠㅠ ## Rose Lash verdict: eyeliner skipped, 15 minutes saved each morning ![Lash brush and aftercare instructions given after treatment](https://img.superchart.com/images/jamsil-flat-lash-extension-rose-lash/jamsil-flat-lash-extension-rose-lash-20-9zkba-900.webp) I loved how thoughtful the director was, even sending me home with aftercare instructions and a lash brush..🥺 My eyes look defined without eyeliner now, which has cut my morning routine before work by more than 15 minutes. Even bare-faced, it looks natural and pretty, and I've been getting so many compliments lately about looking more lively ㅠㅠ I never expected lashes alone could change so much... Such a satisfying visit~! ## Where it is - Rose Lash (로제래쉬) - 21 Olympic-ro 12-gil, Songpa-gu, Seoul, South Korea - 서울특별시 송파구 올림픽로12길 21 5층 - 37.5097097, 127.0833304 - Google Maps: https://www.google.com/maps/search/%EB%A1%9C%EC%A0%9C%EB%9E%98%EC%89%AC/@37.5097097,127.0833304,17z --- Superchart · https://superchart.com/en/@gangwon-notes/jamsil-flat-lash-extension-rose-lash/ · https://superchart.com/llms.txt
