What is Numbing Cream and How Long Does It Take?

Numbing cream is a topical anesthetic, commonly containing lidocaine or a lidocaine-prilocaine mix, applied to the skin before injections, lasers or lifting devices. It typically needs about 20–40 minutes to take effect, and numbness usually fades within one to two hours after removal. At Re:berry Hongdae, numbing time is built into your appointment where needed.

How does numbing cream work?

Numbing creams contain local anesthetics that temporarily block nerve signals in the top layers of skin. They reduce the sharp sensation of needles and surface heat from lasers. They do not fully block deeper sensations, so with treatments such as Ultherapy Prime you may still feel warmth or pressure.

How long does it take?

  • Application: a few minutes to apply evenly, sometimes under a film
  • Waiting time: typically 20–40 minutes, sometimes up to 60 minutes for larger areas
  • After treatment: numbness usually fades within 1–2 hours

Plan your total appointment time to include this step. See How long does a typical appointment take?

Which treatments usually use it?

  • Skin boosters such as Rejuran Healer, PDRN and Laetigen
  • Skin botox and some toxin or filler treatments
  • Lasers such as pico toning, depending on settings
  • Lifting devices such as Ultherapy Prime and Thermage FLX

Treatments such as HydraFacial and LDM usually do not need it.

Are there side effects or precautions?

Temporary redness, paleness or mild tingling is common. Rarely, allergic reactions occur. Tell the doctor if you have reacted to local anesthetics before, have certain heart conditions, or are pregnant. Applying large amounts over wide areas should only be done under medical supervision. Results vary by individual.

How should I plan my visit around numbing time?

For treatments that need numbing, allow extra time in your day. A typical sequence is check-in and paperwork, consultation, cleansing, numbing cream for 20–40 minutes, the treatment itself and a short aftercare briefing. Many patients use the waiting time to read their aftercare notes or ask questions. Arriving without heavy makeup speeds up cleansing. If you are fitting the visit around sightseeing in Hongdae, avoid booking right before a fixed reservation, since timing can shift slightly depending on the plan.

Related questions

Can I apply numbing cream at home before my appointment?

Only if the clinic specifically advises it. In most cases the clinic applies numbing cream so the amount, area and timing are controlled. Applying your own product may cause irritation or interfere with treatment planning. Follow the clinic's instructions for your specific treatment.

Does numbing cream make treatment completely painless?

No. It reduces surface discomfort, but you may still feel pressure, heat or brief sharp sensations, especially with deeper devices. Tell the team during treatment if you need a pause; settings and pacing can often be adjusted. Comfort varies between individuals and treatment areas.

Can I drive after numbing cream?

Topical numbing cream does not usually affect alertness, so driving is generally fine. If you received other medication for comfort, ask the clinic before driving. Many visitors to Hongdae use the subway or a taxi instead. Ask the team if you are unsure about your specific treatment.
