Worried about pain during acne-scar treatments? This guide explains comfort options — from topical numbing to nerve blocks and sedation — so you can plan confidently and know what’s typically needed for each procedure.
At a Glance
- Most acne-scar procedures are performed with topical anaesthesia alone.
- Nerve blocks are sometimes used for deeper or more sensitive areas.
- Sedation is uncommon and reserved for select cases.
- Fractional CO₂ laser discomfort is often reduced with cold-air cooling during treatment.
- Comfort planning is usually discussed and tailored before treatment.
Why Pain Levels Vary Between Acne-Scar Procedures
Discomfort during acne-scar treatment depends on several factors:
- Depth of treatment: deeper procedures stimulate nerves more.
- Area treated: regions like the temples or jawline can be more sensitive.
- Scar type: tethered rolling scars may require deeper work.
- Individual pain threshold: varies widely from person to person.
Understanding these factors helps explain why different analgesia options exist — and why not everyone needs the same approach.
Pain Management Options Explained
| Option | How It Works | Pros | Cons / Limitations | Common Use Cases |
|---|---|---|---|---|
| Topical Anaesthetic Cream | Numbing cream applied 30–45 minutes before treatment to reduce surface sensation. | Non-invasive; widely sufficient; quick recovery. | Limited effect for very deep work. | Fractional lasers, RF microneedling, mild subcision. |
| Local Anaesthetic Injection | Anaesthetic injected directly into the treatment area. | Stronger numbing; targeted effect. | Temporary swelling; brief injection discomfort. | Focal subcision areas; selected deep scars. |
| Nerve Blocks | Anaesthetic placed near specific nerves supplying a region. | Effective regional pain control; longer-lasting numbness. | Not required for all cases; temporary numbness beyond treatment zone. | Extensive subcision in sensitive facial regions. |
| Oral Medication / Sedation | Systemic medication to reduce anxiety or awareness. | Useful for high anxiety or extensive sessions. | Requires monitoring; longer recovery; rarely necessary. | Select cases only, based on clinical assessment. |
What’s Usually Used for Common Acne-Scar Procedures?
- Subcision: Often performed with topical anaesthetic, sometimes combined with local injections or nerve blocks for deeper tethering. Learn more about subcision for acne scars.
- Fractional CO₂ laser: Typically managed with topical numbing; discomfort is often described as heat or stinging. See CO₂ laser for acne scars.
- RF microneedling: Commonly well tolerated with topical anaesthetic alone. Read about RF microneedling for acne scars.
Cold-Air Cooling During Fractional CO₂ Laser
During fractional CO₂ laser, a continuous stream of cold air is often directed at the face throughout the procedure. This helps in two ways:
- Cools the skin surface to reduce heat sensation.
- Provides a distraction effect, making the hot or burning feeling from laser pulses easier to tolerate.
Many patients find cold-air cooling significantly improves comfort during CO₂ treatment.

Frequently Asked Questions
Does subcision hurt?
Most patients describe pressure rather than sharp pain. With topical anaesthetic and, when needed, local injections or nerve blocks, discomfort is usually manageable.
Is sedation needed for CO₂ laser?
In most cases, no. Fractional CO₂ laser is typically performed with topical numbing and cold-air cooling. Sedation is reserved for exceptional situations.
What does the cold air during CO₂ laser do?
The cold air cools the skin surface and distracts from heat sensation during treatment, making the procedure more comfortable.
How long does numbness last after nerve blocks?
Numbness may last a few hours and gradually wears off the same day.
Will pain continue after the procedure?
Post-treatment discomfort is usually mild and short-lived, often described as soreness or tightness rather than pain.
Does pain level predict results?
No. Greater discomfort does not mean better outcomes. Effective treatment focuses on precision and healing, not pain intensity.
Planning a Comfortable Acne-Scar Treatment Experience
Most acne-scar procedures are designed to be well tolerated. Understanding your options — and discussing concerns in advance — helps ensure a smoother, less stressful experience.
