Thinking about acne scar treatment often comes with a big question: Will it be painful?
The idea of needles or lasers can make many people hesitate. But in reality, modern acne scar treatments are supported by safe, effective, and customizable pain management strategies.
From numbing creams to nerve blocks and sedation, there are options to suit every comfort level—so fear of pain doesn’t have to hold you back.
| Method | How It Works | Commonly Used For |
|---|---|---|
| Topical anaesthetics (numbing creams) | Applied to skin surface; block nerve signals | Lighter treatments like microneedling, TCA CROSS, fractional lasers |
| Local infiltration | Anaesthetic injected directly into treatment area | Subcision, fillers, focal scars |
| Field block | Anaesthetic injected around broader region | Larger treatment zones, multiple scars |
| Nerve blocks | Anaesthetic near facial nerves to numb entire regions | Cheeks, lips, forehead, jawline scars |
| Cooling / non-pharmacological | Cold air, ice packs, vibration devices, relaxation techniques | Mild procedures or in combination with anaesthetics |
| Sedation / anxiolysis | Oral medication, nitrous oxide, or IV sedation | Patients with high anxiety or undergoing longer treatments |
| Post-procedure relief | Paracetamol, cold compresses, gentle skincare | Aftercare at home |
Topical Anaesthetics: First-Line Comfort
Topical anaesthetics are often the first step in pain management during acne scar treatments such as TCA CROSS, fractional laser resurfacing, and microneedling.
These numbing creams work by blocking sodium channels in nerve endings, reducing pain signals.
With an occlusive dressing, effects kick in within 30–45 minutes and last about 1–2 hours.
Common Options:
- EMLA Cream: Lidocaine + prilocaine (2.5% each); used for microneedling, TCA CROSS.
- Pliaglis: Lidocaine + tetracaine (7% each); ideal for fractional CO₂ laser.
- Compounded creams: Custom 7–10% lidocaine blends for deeper resurfacing (used under doctor supervision).
Local Infiltration and Field Blocks
When numbing creams aren’t enough, injections offer deeper relief. These methods involve injecting anaesthetic (like lidocaine or bupivacaine) directly under the skin.
Techniques:
- Local infiltration: For subcision or individual scars.
- Field block: For multiple scars across broader areas.
Duration: 1–4 hours depending on technique and formulation.
Nerve Blocks for Targeted Pain Relief
For patients undergoing treatment on multiple facial zones, nerve blocks offer targeted, long-lasting relief.
Common Facial Nerve Blocks:
- Infraorbital: Numbs midface & upper lip (cheeks)
- Mental: Covers jawline and chin
- Supraorbital: Forehead & upper eyelids
- Zygomaticofacial: Lateral cheek region
Cooling and Non-Pharmacological Pain Relief
Not all pain management methods are pharmacological. Cooling and distraction techniques are safe and effective, particularly for lighter procedures.
Options Include:
- Cryo cooling (Zimmer Cryo): Chilled air blown on skin during treatment
- Ice packs: Used before/after for swelling
- Vibration devices: Distract nerves via “gate control”
- Relaxation techniques: Breathing, music, guided conversation
Sedation and Anxiolysis for Anxious Patients
For highly sensitive or anxious patients, sedation can ensure a calm experience.
Options:
- Oral anxiolytics: Taken 30–60 mins before procedure
- Nitrous oxide (laughing gas): Fast-acting, wears off quickly
- IV sedation: For longer or more invasive sessions (performed under medical supervision)
Post-Procedure Pain Relief and Comfort at Home
After treatment, most patients experience mild discomfort like swelling, redness, or tenderness.
At-Home Relief:
- Paracetamol: For pain
- Cold compresses: Reduce swelling
- Fragrance-free skincare: Gentle cleansing and moisturizing
- Soothing gels: Aloe vera or barrier creams
When to Contact Your Clinic:
- Increasing pain after 48 hours
- Unusual swelling, bruising, or discoloration
- Persistent numbness or tingling
Frequently Asked Questions
How do clinics decide which pain relief method to use?
Clinics match the method to procedure type, scar severity, treatment area, and patient comfort needs. This tailored approach balances safety, effectiveness, and overall treatment experience.
Can multiple pain management methods be combined?
Yes. For example, numbing cream may be paired with cooling devices or local injections. Combining methods is sometimes used to help manage discomfort during longer or more invasive sessions.
Do pain relief options add extra time to the session?
Some methods, like numbing creams, require 30–45 minutes for preparation. Others, such as cooling or injections, add only a few minutes before treatment begins.
Are there any side effects from anaesthetics?
Minor redness, tingling, or swelling may occur, but these usually resolve quickly. Serious complications are rare when procedures are performed by trained professionals following medical standards.

Pain management methods are available to help patients undergo acne scar treatments with greater tolerance. With methods ranging from numbing creams and cooling to injections, nerve blocks, and sedation, comfort can be customized to suit every patient’s needs.
