Dongtan body contouring salon: Spelton and Biophoton at Celtune Five
In short
Celtune Five is a diet and body contouring studio built around constitution consultations, on the 3rd floor of Grand Passage near Dongtan Lake Park in Hwaseong, Gyeonggi. The session at Celtune Five started with a constitution consultation and an InBody measurement, then moved on to Spelton care received lying down and Biophoton care using growth light. Even lying still without any effort the sweat came out steadily, so Celtune Five suits anyone who wants machine-based body care together with a proper consultation.

These days I've come to think dieting isn't just about working out harder or eating less. So this time I tried a different approach to diet body care in Dongtan, and visited Celtune Five.
I went in thinking it would just be machine-based body care, but it turned out to be a bit different — they first do a constitution consultation and InBody measurement, and the care follows based on those results.
※ Business hours and prices may change depending on when you visit and how the studio is operating, so I'd recommend checking before you go.
Where is Celtune Five, and where do you park? Room 3089, Grand Passage 3rd floor
Celtune Five is on the 3rd floor of Grand Passage near Dongtan Lake Park, room 3089. The building has underground parking, but since it was my first visit I didn't know that and parked at a nearby public parking lot instead and walked over. Next time I'll just use the building's underground parking.

Take the escalator up to the 3rd floor — it can be a bit tricky to find from there.

Turn left, then left again, then right and go straight and you'll find it. The building is big, so finding the exact spot wasn't easy. Just look for room 3089 and follow the signs!


Inside, the consultation space and the care space were both neatly organized, and since it's run by reservation, the vibe was calm rather than crowded.




Celtune Five starts with a constitution consultation, not the machines

The first thing at Celtune Five was a constitution consultation. Even if people eat the same food or try the same diet method, everyone's body condition and lifestyle habits are different, so finding a direction that suits the individual matters — that's what they explained.

When I actually had the consultation, it wasn't the simple 'just exercise to lose weight' kind of talk. We talked about my usual lifestyle and eating habits, and I got an explanation of how best to manage my body condition.
What stuck with me most was the idea that even with dieting, it's important to find what works for you rather than just following what everyone else does. It was a different approach from how I usually just look things up myself and try random things, so it was interesting.
What Celtune Five gives you to change into before the session


Before the care started, I changed into the clothes provided. They gave me disposable underwear and a gown separately, which I personally found quite comfortable.

You just hang your own clothes to the side. Since it's run by reservation and I was the only one there, I could just hang them up and change back after the care was done.
I wore the gown throughout the Spelton and Biophoton care. It turned out to be a surprisingly sweaty session, so if I'd kept my own clothes on I think I would have been a bit self-conscious. But changing into the disposable underwear and gown meant I didn't have to worry about sweating a lot.

After the consultation, I changed into the provided clothes and had my InBody measured. This InBody was measured again after the care ended, so I could compare before and after.
What does Spelton care at Celtune Five feel like lying down?

After the consultation at Celtune Five, I received Spelton care first. Spelton is a care you receive lying completely still — but it's not just a vibration tapping one spot, it felt like the whole body moving in waves.

At first I thought, 'can lying down really count as exercise?' but once I actually tried it, my body moved rhythmically and it felt surprisingly unique. The director explained that this kind of movement in Spelton is different from ordinary vibration.
What I liked most was that I could receive it lying down comfortably. I didn't have to exert any effort or move — I could just lie there relaxed the whole time.
Apparently if your body's circulation is good, you won't feel any pain during this process, but if circulation is blocked, you might feel a faint tingling sensation. They said people with really blocked circulation can even feel a stinging sensation beyond that — I just felt some tingling!
Biophoton care: the warm part of the Celtune Five session

After Spelton care finished, I moved on to Biophoton care. At first I thought this would just be ordinary heat therapy warming the body, but the director explained the science behind the machine.

Biophoton apparently uses a light called 'bio-photonic light.' According to the director, it delivers heat deeper into the body than ordinary heat therapy or far-infrared.
I was especially curious when they explained that it 'delivers heat deep enough to reach the bones' — and lying there receiving it, it really did feel like the whole body was gently warming up rather than just the surface of the skin getting hot.


Throughout the care, I kept feeling that warm heat, and I sweat quite a lot, more than expected. I'd changed into the disposable underwear and gown that day, and since it was such a sweaty session, I was glad I had those on instead of my own clothes.
Personally, Spelton felt like the body was being moved, while Biophoton felt like gently warming the body with heat — the two cares felt quite different from each other. If you want a different kind of heat therapy from the intense sweating of a Korean jjimjilbang (sauna), this was the kind of experience that made me think, 'oh, this kind of care exists too.'
InBody before and after, compared right after the session
< Before care >

This was the part of the experience I found most surprising. I had my InBody measured before care and again right after, and comparing them side by side, the numbers had actually changed.
- InBody score: 83 → 88
- Muscle mass: 25.7kg → 26.6kg
- Body fat mass: 13.1kg → 11.1kg
It was surprising to see the numbers change this much from just one session.
< After care >

That said, since this is the change measured on the same day before and after, it's probably more accurate to see it as the measured values changing that much rather than assuming my actual muscle and body fat changed by those exact amounts.
The director explained that for people whose circulation isn't too blocked, this kind of noticeable before-and-after change can happen. Seeing the numbers compared right in front of me was definitely fun.
Was Celtune Five worth it for body contouring in Dongtan?
Visiting Celtune Five this time, what stood out was how much weight the constitution consultation carried — more than I expected. It wasn't just machine care and done; it was a full process of first consulting on constitution and lifestyle habits, checking the current state with InBody, and then receiving Spelton and Biophoton care.
Especially for people who, like me, have dieted alone and vaguely wondered,
"What should I eat?" "How should I exercise?"
I think it's worth trying a consultation on your own lifestyle and body condition first. And for first-time visitors like me, it's good to know ahead of time that you can use the building's underground parking.
Overall, this experience felt refreshingly different from the diet care I was used to, and comparing the before-and-after InBody results right on the spot was the part that stuck with me the most.
