Lately, eye makeup has been quietly bothering me every time I do my makeup. Even with mascara, my eyes never look quite as defined as I want, and honestly, doing my eyelash curler and mascara routine every morning takes up a surprising amount of time.


So this time I wanted to make things a little easier for myself, and while looking into lash extensions near Seonjeongneung, I ended up visiting On The Boutique. I got flat lash extensions, done by Director Rahee :)
Where is On The Boutique? A short walk from Seonjeongneung Station
On The Boutique is near Seonjeongneung Station, so it was easy to get to by public transit. On days when I'm moving around without a car, being close to a station really matters.

Since it's close to Seonjeongneung Station, I could book a visit in the middle of a busy day without much hassle, and the location seemed good for going back regularly too. Lash extensions aren't really a one-and-done thing — you end up thinking about retouches and repeat visits — so easy access is a real plus.
The eye-shape consultation before the lash extensions
At On The Boutique, they don't just jump straight into the treatment — they first look at your current eye shape and lash condition and go through a design consultation. I think with lash extensions, it's less about going as long and full as possible and more about what actually suits your own eyes naturally.


I was able to fully explain the vibe I wanted, and rather than just following my request exactly, it felt like she was working with me to find a direction that would actually suit my eyes.
I wanted something that made my eyes look defined without being over the top — overall a style that would match my face well — and I loved that she suggested options with that in mind. Lash length and curl alone can change your whole impression quite a bit, so having a thorough consultation before starting made me feel a lot more at ease.
How flat lash extensions changed my daily eye look
What I chose at On The Boutique this time was flat lash extensions. Lash extensions definitely make your eyes look more defined, but if they end up too heavy or dramatic, they can feel like a lot for everyday wear.

This time the design was set up to naturally suit my eyes, so overall it felt clean but still clearly defined. What I loved most was that my lashes looked so much fuller when my eyes were open that I didn't need heavy eye makeup for my eyes to stand out.



I was especially happy that the lashes looked naturally connected whether I looked from the side or straight on. This is probably why people keep coming back once they try lash extensions, haha.
Being able to cut down on the morning curler-and-mascara routine is also a big plus for me personally! I think it'd be great to get done before a trip or an important event too.
Retouch price and the 3-week window
On The Boutique offers a long retouch window of up to 3 weeks after the extension service, and retouches cost 30,000 won. Aftercare really matters once you've gotten lash extensions.
In everyday life, some lashes naturally fall out over time, so I liked that there's a retouch window of up to 3 weeks. You can get a retouch based on how things look before going in for a full new set, which seems great for anyone who wants to keep up with maintenance regularly.
Naver booking discount and repeat-visit events
On The Boutique takes bookings through Naver Reservation, so it was easy to check available dates and times and book in advance.

There's also a discount for booking through Naver Reservation, and since they're open every day, it's worth noting that you can visit whenever fits your schedule, whether that's a weekday or weekend.
They're currently running some events too — 3,000 won off for repeat visits and 5,000 won in credit for referring a friend — so if you're planning to keep up with lash maintenance, it's worth keeping in mind.

What I liked most was that instead of just going all-out flashy from the start, she looked at my eye shape and existing lashes, consulted with me on the design, and reflected the vibe I wanted to create a natural result.


Lash extensions might seem like a small change, but they can shift your whole facial impression, so I think it really matters to find a place that takes the design consultation seriously.



They even gave me a lash brush to take care of them properly, haha. If you're looking for natural, well-matched lash extensions near Seonjeongneung Station, or you've been curious about flat lash extensions, check out On The Boutique :)
