Botox in Korea: Results Timeline, Aftercare and Trip Planning

Researched by the Clinic KR editorial team. Sources checked October 9, 2026. Not reviewed by a physician: use it to prepare questions for your surgeon.

Short answer: most people see Botox results within 3 to 7 days (American Academy of Dermatology), the full effect within about a week, and the effect lasts about three to four months. On exercise, medical sources disagree: wait two hours (AAD), avoid strenuous activity for the rest of the day (The Aesthetic Society), or resume normal activities immediately (ASPS). All say not to rub or massage the area. No medical source gives a rule for saunas, swimming, alcohol or flying. For a trip, have Botox early so any bruise can fade, and plan any touch-up for a later visit.

After Botox: timing of effects and aftercare Strenuous exercise: wait two hours to the rest of the day. First effect: one to two days. Results visible: 3 to 7 days. Bruising, if any: about a week. Eyelid droop, if it happens: about 1 percent in trials, median onset day 9. Touch-up check: a few weeks after treatment. After Botox: timing of effects and aftercare Day 0 is the treatment day. Sources: AAD, The Aesthetic Society, FDA label and trial data. 0 7 14 21 days Strenuous exercise Wait 2 hours (AAD) to the rest of the day (Aesthetic Society) First effect Starts one to two days after (FDA label) Results visible Within 3 to 7 days (AAD) Bruising, if any Lasts about a week (AAD) Eyelid droop, if any About 1%; median onset day 9 (Brin 2024) Touch-up check Weeks later (Aesthetic Society)
Eyelid droop data are from pooled trials of 3,431 people treated for upper facial lines; it lasted a median of 28 days.

How Botox works

Botulinum toxin relaxes the muscles that cause expression lines, such as frown lines, forehead lines and crow’s feet. Injections take less than 15 minutes (ASPS). Clinics in Korea offer both imported and Korean-made botulinum toxin products. Ask which product and how many units you received.

When results appear

The FDA label says the effect starts one to two days after injection and increases during the first week. In one study, 93 percent of patients reported an effect by day 3 (Beer et al., 2011). In a randomised trial of 180 patients, average onset in women was about 3 days for incobotulinumtoxinA and about 5 days for onabotulinumtoxinA and abobotulinumtoxinA (Rappl et al., 2013). The effect lasts about three to four months, and sometimes longer (AAD).

Exercise, lying down, heat and flying

  • Exercise: the AAD says wait two hours before strenuous activity, including lifting heavy items and working out. The Aesthetic Society says avoid it for the rest of the day. ASPS says you can resume normal activities immediately.
  • Rubbing and massage: do not rub or massage the treated areas, because the toxin can spread and cause temporary drooping (ASPS, AAD). Makeup can go on straight away if you do not press it in (AAD).
  • Lying down: The Aesthetic Society advises avoiding lying down or bending over after injection but gives no number of hours.
  • Sauna, jjimjilbang, swimming, alcohol, flying: no medical society, regulator or trial we found gives a rule. A 2026 computer simulation estimated very small extra spread from exercise, heat, rubbing or bending in the first four hours, but its authors say clinical trials are still needed (Rahman et al.). If you want to be cautious, leave saunas and hard workouts until the next day.

Side effects and when they appear

Bruising lasts about a week (AAD). Side effects usually appear within the first week (FDA label). Eyelid drooping is the side effect most people worry about: in pooled trials of 3,431 people, it happened in about 1 percent, most often around day 9, and lasted a median of four weeks (Brin et al., 2024). That timing means it would usually show up after a short trip. If it happens, contact your clinic, and the FDA medication guide advises not driving.

How long to stay in Korea

The British Association of Aesthetic Plastic Surgeons (BAAPS) groups procedures for people who travel abroad. Treatments done under local anaesthetic in under 90 minutes are in its lowest group, with no extra time in the destination country needed for travel reasons. The NHS advice about waiting before flying is written for surgery, not for treatments like this one.

So what decides the length of your stay is the treatment itself: bruising and timing. A bruise lasts about a week, so having Botox early in a trip gives it time to fade. The Aesthetic Society suggests a follow-up a few weeks later for a touch-up, which a short trip cannot include, so ask whether a touch-up can wait for your next visit.

A sample 3 to 5-day plan

Days Plan
Day 1 Arrive. Consultation and Botox the same or next day.
Treatment day No rubbing. Skip hard exercise and the sauna until the next day if you want to be cautious.
Days 2 to 5 Normal sightseeing. Results start appearing from day 3.

Replace every date with the ones your clinic gives you. The Clinic KR trip planner lays them out day by day and flags a flight that is booked too early.

Questions to ask your clinic before you book flights

  1. Which product and how many units will you use, and can I have that in writing?
  2. Which areas will you treat?
  3. Can a touch-up be done on my next visit if one side looks uneven?
  4. What should I do if an eyelid droops after I am home?
