저속노화 (jeosongnohwa) — Not Getting Younger, Just Aging More Slowly
저속노화 (jeosongnohwa) means slowing down the speed at which your body ages, using nothing but everyday habits. It isn’t about becoming younger, and it isn’t about erasing wrinkles. You still get older — you just turn the dial down on how fast it happens. These days Koreans in their twenties and thirties bring it up while picking a lunch spot, or halfway through putting a pot of water on for ramyeon at eleven at night. You’ll hear 나 요즘 저속노화 중이야 (na yojeum jeosongnohwa jung-iya) — “I’m doing jeosongnohwa these days” — far more often than 오늘은 야식 안 먹을래 (oneureun yasik an meogeullae), “I’m skipping the late-night snack tonight.”
It’s pronounced [저송노화] (jeosongnohwa). The final ㄱ of 저속 changes to ㅇ when it meets the ㄴ that follows, so reading it out letter by letter as “저속-노화” actually sounds more awkward, not less.
There’s one place Korean learners slip on this word more than anywhere else: assuming 저속노화 is simply the Korean translation of “anti-aging.” The two point in opposite directions. Anti-aging is about undoing what has already appeared — procedures, cosmetics, how you look. 저속노화 is about delaying what hasn’t appeared yet. That’s why the word lives at the dinner table, in bed, and on the stairs, not at the dermatologist’s office. Every example and quiz in this post pokes at that one difference from a different angle.
The emotional temperature is surprisingly light. Even with 노화 (nohwa, “aging”) — a heavy Sino-Korean word — sitting inside it, the term gets passed around like a joke, like self-deprecation. Someone posts a photo of multigrain rice captioned 오늘의 저속노화 (oneurui jeosongnohwa), “today’s jeosongnohwa,” and then orders fried chicken and writes 오늘은 저속노화 실패 (oneureun jeosongnohwa silpae), “jeosongnohwa: failed today.” It wears the face of a serious medical term, but in actual use it’s much closer to a buzzword.
Seeing it in a real conversation
Scene: 11:30 pm, the convenience store in front of the office. Two people run into each other right at the cup-ramyeon shelf.
Jun-kyung: 어, 에밀리? 이 시간에 여기 웬일이야. Oh, Emily? What are you doing here at this hour?
Emily: 야근 끝나고 배고파서. 근데 너 손에 든 거 뭔데? I just finished overtime and I’m starving. But what’s that in your hand?
Jun-kyung: 아… 이거? 나 요즘 저속노화 한다고 사무실에서 떠들고 다녔는데. Ah… this? And here I’ve been telling the whole office I’m doing jeosongnohwa these days.
Emily: 야, 밤 열한 시 반 컵라면은 저속노화가 아니라 그 반대지. Dude, instant noodles at 11:30 pm isn’t jeosongnohwa — it’s the exact opposite.
Jun-kyung: 알아, 아는데… 오늘 하루만 좀 봐줘라. I know, I know… just let me off the hook for today.
Emily: 봐줄게. 대신 내일 점심은 잡곡밥이다. Fine. But tomorrow’s lunch is multigrain rice.
Used this way, it sounds off
✗ (to a senior colleague you haven’t seen in a while) 선배님, 얼굴이 좀 상하셨네요. 저속노화 좀 하셔야겠어요. Seonbae-nim, you look a little worn down. You should do some jeosongnohwa.
✓ (about yourself) 저 요즘 저속노화 해 보려고 저녁엔 잡곡밥 먹어요. I’m trying jeosongnohwa these days, so I eat multigrain rice for dinner.
→ Pointed at someone else’s face, it turns into “you look old.” This word is almost always something you say about your own life, not something you recommend to another person. If you really want to suggest it, steer around to something like 요즘 그런 식단이 유행이더라고요 (yojeum geureon sikdani yuhaeng-ideoragoyo), “that kind of diet seems to be trending lately.”
✗ 저 어제 피부과에서 레이저 받았어요. 완전 저속노화죠. I got laser treatment at the dermatologist yesterday. Total jeosongnohwa, right?
✓ 저 어제 피부과에서 레이저 받았어요. 요즘 안티에이징에 관심이 많아서요. I got laser treatment at the dermatologist yesterday. I’ve been really into anti-aging lately.
→ 저속노화 isn’t about reversing your appearance. It’s about changing the speed at which you eat, sleep, and move, so it doesn’t attach to talk of procedures or cosmetics. 안티에이징 (anti-eijing) is the right word here.
What would you say in this situation?
It’s midnight, and a friend posts in the group chat: 치킨 시킬 사람? (chikin sikil saram?) — “anyone want to order fried chicken?” You want to sit this one out. Which sounds more natural?
- A: 나 저속노화 중이야. 오늘은 패스.
- B: 나 안티에이징 중이야. 오늘은 패스.
The answer is A. Turning down a late-night snack is about your whole eating-and-sleeping life, and that’s exactly the territory 저속노화 covers. B is grammatically fine, but it lands like “I’m doing a skincare routine, so no chicken for me,” and the listener pauses for a second. On top of that, bringing up anti-aging among friends suddenly makes it a conversation about looks. A stays light and leaves room for a joke back — the other person can tease you with 그러다 내일 라면 먹더라 (geureoda naeil ramyeon meokdeora), “yeah, and tomorrow you’ll be eating ramyeon.” That’s exactly the right weight.
Example sentences by situation
1. Picking a lunch spot with coworkers
오늘은 국수 말고 다른 데 가자. 나 저속노화 중이라 면은 좀 참으려고. Oneureun guksu malgo dareun de gaja. Na jeosongnohwa jung-ira myeoneun jom chamneuryeogo. Let’s go somewhere other than the noodle place today. I’m doing jeosongnohwa, so I’m laying off noodles for a bit.
When everyone’s choosing a place to eat, this line isn’t a refusal — it’s a negotiation. Saying “no, I don’t want to” freezes the mood, but giving 저속노화 as your reason gets everyone laughing and looking up another restaurant. Because you’re leaning on a trend everybody knows rather than a personal preference, the edge of the refusal gets dulled.
2. On the phone with your parents (polite speech)
엄마, 저 요즘 흰쌀 대신 잡곡밥 먹어요. 저속노화 하려고요. Eomma, jeo yojeum huinssal daesin japgokbap meogeoyo. Jeosongnohwa haryeogoyo. Mom, I’ve been eating multigrain rice instead of white rice lately. I’m trying to do jeosongnohwa.
For your parents’ generation this may be an unfamiliar coinage, so adding a quick 천천히 늙자는 거예요 (cheoncheonhi neukjaneun geoyeyo), “it means aging slowly,” right after keeps the conversation smooth. This habit of using the new word and unpacking it is especially useful for Korean learners.
3. Making fun of yourself
새벽 두 시에 라면이라니. 이건 저속노화가 아니라 가속노화지. Saebyeok du si-e ramyeon-irani. Igeon jeosongnohwaga anira gasongnohwaji. Ramyeon at two in the morning. This isn’t jeosongnohwa — this is gasongnohwa (accelerated aging).
Half the time this word shows up in a failure story. It’s a slightly unusual buzzword: it appears more often when people fall off the wagon than when they stay on it.
Polite and casual forms, and similar expressions
저속노화 is a noun, so you attach 하다 (hada) to use it as a verb. Casual: 저속노화 해 (jeosongnohwa hae). Polite: 저속노화 해요 / 저속노화 하고 있어요 (jeosongnohwa haeyo / jeosongnohwa hago isseoyo). That said, as the table below shows, the word itself is a light, trendy one — in formal settings or with someone older than you, it’s safer to explain the idea in plain words instead.
| Expression | Tone & intensity | Where it’s used |
|---|---|---|
| 저속노화 (jeosongnohwa) | Light, self-deprecating, very current | Peers, social media, family. Talk about daily habits |
| 가속노화 (gasongnohwa) | Half-joking self-blame | When you regret a late-night snack or an all-nighter. The counterpart to 저속노화 |
| 안티에이징 (anti-eijing) | Neutral, consumer/beauty side | Dermatology, cosmetics, procedures |
| 건강 관리 (geongang gwalli) | Neutral, safe anywhere | Work, elders, official settings |
When you’re turning down a late-night snack with someone senior to you, 요즘 건강 관리 중이라서요 (yojeum geongang gwalli jung-iraseoyo), “I’ve been taking care of my health lately,” goes over better than 저속노화 중이라서요. The latter carries the joking temperature of talk between peers.
Cultural background — the trend of one bowl of multigrain rice
The word-building is simple: 저속 (低速, low speed) + 노화 (老化, aging). Its counterpart is 가속노화 (加速老化, gasongnohwa) — the same thing with 가속, “acceleration,” attached instead. In other words, the frame of this word isn’t “aging or not aging,” it’s “fast or slow.” In Korean, 노화 used to be a stiff Sino-Korean word that lived in hospitals and academic papers, but the moment a speed word was fixed to the front of it, it came down to earth and started describing everyday choices.
The interesting part is who uses it. It’s a word about aging, yet the people saying it most are not in their sixties but in their twenties and thirties. Multigrain rice instead of white rice, an early bedtime instead of a late night, the stairs instead of the elevator — the unit of the story isn’t some grand resolution, it’s how you ate one meal today. The photos that go up on social media aren’t from a hospital or a gym either; they’re usually of a dinner table.
So the word carries the self-mockery that’s so characteristic of Korean buzzwords. It isn’t the language of someone keeping the rules perfectly; it’s the language of someone who keeps trying and keeps failing. That’s why 오늘은 저속노화 실패 (oneureun jeosongnohwa silpae), “failed at jeosongnohwa today,” shows up far more often than 오늘은 저속노화 성공 (oneureun jeosongnohwa seonggong), “succeeded at jeosongnohwa today.” The same goes for learners of Korean using it: it fits most naturally when you’re confessing a failure with a grin, not when you’re solemnly declaring a plan.
Today’s quiz
Which of the following sentences uses 저속노화 awkwardly?
- 나 오늘부터 저녁에 잡곡밥 먹기로 했어. 저속노화 시작이야.
- 어제 새벽 세 시에 잤어. 이건 저속노화가 아니지.
- 부장님, 요즘 피곤해 보이시는데 저속노화 좀 하세요.
Answer: number 3. 저속노화 is something you say about your own life, so recommending it to someone else — especially someone senior to you — comes across as pointing out that they look old. On top of that, it’s a light buzzword, so the temperature is all wrong for addressing your department head. Here, something like 요즘 무리하지 마세요 (yojeum murihaji maseyo), “don’t push yourself too hard these days,” is the safe choice. Sentences 1 and 2 describe success and failure respectively — the two most typical uses of this expression.
