Complete Pre-Treatment Guide for Medical Aesthetics in Seoul | Rappoel Clinic 2026



Why Pre-Treatment Preparation Matters

Proper pre-treatment preparation is not just about following rules — it directly impacts treatment safety and outcome quality. Many patients who experience suboptimal results or unnecessary side effects can trace the issue back to inadequate preparation. Below are Rappoel Clinic’s key pre-treatment guidelines by treatment category.

📍 Rappoel Dermatology Clinic · 5F, 77 Seocho-daero, Seocho-gu, Seoul · 3-min walk from Gangnam Station Exit 10

Universal Pre-Treatment Rules (All Procedures)

  • Disclose all medications: Including aspirin, fish oil, vitamin E (blood thinners) — these typically need to be paused 1 week prior (confirm with your doctor)
  • Avoid alcohol: No alcohol 24–48 hours before treatment to reduce bruising and swelling risk
  • Disclose allergies: Including local anesthetic allergy, skin sensitivities
  • No active skin infection: The treatment area must be free from active breakouts or skin infections

Pre-Treatment Guidelines for Filler (Hyaluronic Acid)

Before Filler Treatment

Pause aspirin and fish oil at least 7 days prior. Inform the doctor of any previous hyaluronic acid injections (brand, area, timing). Confirm no active cold sores (especially critical for lip filler). Fasting is not required.

Pre-Treatment Guidelines for Botulinum Toxin

Before Botox Treatment

Disclose any previous botulinum toxin injections (brand, area, date). Pause blood thinners 1 week prior. Avoid intense exercise before the appointment (stay calm). No fasting required.

Pre-Treatment Guidelines for Laser / Microneedling

Before Laser / Microneedling

Stop all retinoid (vitamin A) products at least 5–7 days before. Avoid prolonged sun exposure for at least 1 month prior to laser. Disclose any keloid/hypertrophic scar history. Arrive with a clean, makeup-free face on the day of treatment.

Mental Preparation for First-Time Patients

It’s completely normal to feel nervous before your first aesthetic procedure. At Rappoel, every patient receives a thorough consultation before any treatment — the doctor explains the procedure in detail, confirms your goals and expectations, and answers all questions. You are always encouraged to ask anything at any point.

Frequently Asked Questions

Do I need to fast before medical aesthetic treatments?
Most non-surgical aesthetic procedures (injectables, fillers, laser) do not require fasting — you can eat normally. Fasting is only required if nitrous oxide or IV sedation is used, which the doctor will communicate in advance.
How long should I stop fish oil and vitamin E before injections?
At least 7 days before treatment to reduce bruising and bleeding risk. Aspirin may require 5–7 days as well. Always disclose all supplements and medications at your consultation so the doctor can assess what needs to be paused.
I just got a tan from the beach — can I do laser right away?
Not recommended. Sun-exposed skin is sensitized with elevated melanin activity, which increases the risk of uneven pigmentation or post-inflammatory hyperpigmentation from laser. Wait at least 2–4 weeks after your last significant sun exposure for skin to stabilize.
I have a history of cold sores — can I get lip filler?
Lip filler is strictly contraindicated during an active herpes outbreak. After full recovery, patients with cold sore history should take prophylactic antiviral medication (prescribed by the doctor) before lip filler as a precaution.
Does Rappoel Clinic conduct a full assessment before treatment?
Yes. Every patient receives a thorough facial assessment and medical history review before any procedure. Rappoel doctors create a personalized treatment plan to ensure both safety and optimal outcome.
What documents should I bring for my first consultation?
First-time patients (especially international visitors) should bring a valid passport or ID. If you have past aesthetic treatment records or allergy documentation, bring those for reference. No other special materials are required.
